Journalism Development

The impression created by the media over years has been held with mixed feelings. Whereas some media corporate world are known to have positively helped transform societies politically, economically, culturally and technologically; some other have only torn the world apart through negative reporting that supports aggressive confrontation, glorifying terror activities to make eye-catching headlines with selfishly money motive.

Similarly, the aggressive, corrupt and oppressive groups and individuals (religiously, politically or economically) have been glorified in the way that sustains situation that steadily extinct some societies.

Their content hardly provided or suggested solutions to alarm-triggering headlines. And much of the media activities have lacked an element of social responsibility that is tangible to give a voice to the voiceless and direct transformative opportunities to the poor, disabled and other disadvantaged groups

Journaling is a key communication tool. All organisms by nature communicate either verbally or non-verbally, yet attempting to make sense of whatever cues that are exchanged or evaluated.

True, we tend to be evaluative of one another whilst trying to figure out what intentions the other party could have towards you. The aim can be to help measure up the relationship that possibly could be developed, whether health or not.

Of course, in certain encounters some people could be threatened, suspicious, lack confidence, defensively withdraw or get on well in a healthy and rewarding relationship. This, indeed, is how communities can influence attitudes and behavior towards one another. That way, we could manage, control and direct directs and behavior. What a powerful tool a pen can be!

But success through journaling it self needs a period of training and practical experience, such that we can communicate to effectively make or unmake relationships or evolve life through the aspects of observing, reading and listening to words and actions of others and things.

The primary motivators to writing is the element of having an opinion yet unique. As part of research steps, one would be required to publish a final report or summarized article from the investigations, results and analyses carried out. Other researchers or students would want to review literature about statements pending investigation. From their successes, investigators either get awards or promotion.

Through practical experience, some people make careers out of their abilities and skills to communicate effectively as writers, as advertising agents, as interpreters and, as counselors or therapists.

Secondary employment too could be provided by journalism like driving, distribution, sale or retailing, legal advising et cetera. Eventually, those associated to it could become social icons or global media giants.

On the other hand, journaling could have important health benefits as stress reliever. By writing about one’s traumatic experience, sufferer could drop so much mental toxins off him or her.

And, at the same time it would help improve on analytical and problem-solving skills crucial in successful dealing with the ever emerging challenges encountered in day-to-day life.

From the natural or ecological sense, journaling or communication significantly help to connect different elements of the eco-system -through the principles of interconnectivity and interdependence.

And through media, we can help improve the dangerous global situations as nuclear conflicts, to make the world a better place for everyone to live in. But this would only be so if we formed a common objective in solidarity to it (non-violence) under the principle of conscious non-violence through tolerance and respect for divergent views.

Go Green With Natural Finishes – environmental friendly finishes

Finishes are coatings that are  applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear.  They also improve the appearance of the structure and are used to enhance the design of rooms.

Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource.  There are now paints and finishes on the market that are derived from a renewable resource, which  in a small way, helps to reduce dependence on oil, and  contributes to a more sustainable world.

The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD).  This increases the burden on waste treatment facilities, and can also pollute our natural water sources.  In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.

When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world.  And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.

Low and no VOC paints have less smell and less impact on air quality.  EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.

Switching will not cost you more.  Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused.  The paint is still washable, and is far less harmful to you, your pets, and the environment.

How Can Technology Help the Environment?

How can technology help improve the environment? Are we promoting a more singular existence, where individualism is the force that is driving us along? We are now living in a world that is in an accelerated mode of change and innovation. Is this rate of change detrimental to our existence? Think about this for a moment. On the one hand we have improvements in all areas of our lives some are greater than others. On the other hand we are looking at the effects of the harmful destruction of our planet earth.

The first computers started to emerge around the 1940’s, now we have computer processors in a lot of the electronic equipment we use every day. We even have computers that can fit in your hand that have more power than the first computers.The first Television and television transmission appeared in 1925 and now we are watching gigantic flat screens, some as big as buildings and others screens as small as wrist watches. In the past 80 years the medical field has also grown in leaps and bounds in the areas of IVF, genetic research, cloning, stem cell research, along with the progress in the prevention, cure and management of various diseases. Other fields such as astronomy, environmental science, weapons/warfare and engineering have also had their fair share of extraordinary development achievements.

Looking at the issues of Global warming and human environment interaction we are currently facing within our natural environment. Should we really be in a race to ruin the land where we live? We cannot keep up with the current technology, just look at all the equipment you have taken to the recycle tip in just the last 12-24 months. Consider how many Televisions, Videos, DVD players, Computers, Laptops, Hi-fi’s and Home entertainment systems you have changed or bought recently, the list is endless. When an improvement is made to a product it can sometimes make the original product obsolete. Satellite Navigation equipment a new and easily available product for everyone. Even if you only use it once a year it is believed to be a must have product. Mobile phones is another product every man and his dog has one these days. How often do you change your mobile phone for the latest model? Can you ever imagine being without a mobile phone? How did we ever cope without them? The raw materials used to make a phone cannot be recycled easily. 

I believe as we get to understand one part(s) of our lives we seem to lose sight of others parts that are equally as important. What can be done to slow down the rate of change or how do we as a nation become more aware of the effects of the rate of change has on our environment.

If we could not have a new television or other new product until the old one had been recycled properly we would help the environment tremendously. Today if we implemented this many products or versions of products would be missed because of the speed at which technology changes. Like the latest flat screen with super clear picture quality. It seem that every other week we get the next new and improved product. Just look at washing power or washing up liquid advertisements.

Just some food for thought more to come soon.

The Holy Grail of Reduction

The hard truth is that we all need to reduce. Reduce the amount of money we spend. Reduce the amount of food we eat…and our waistlines. And reduce the amount of stuff we throw away. In fact new we look at the 3 R’s of reduce, reuse, recycle, they are actually in that order for a reason. It is a hierarchy for a reason and reduce is the Holy Grail. Put in its simplest terms reduce means that we use less of the earth’s resources and in any environmental scheme should be our first priority.

That said, it is also the hardest to accomplish. When I thought about all the things we do to be greener, the number of examples of reducing stumped me. I suppose the most obvious example of our efforts to reduce was the decision some months ago, not to purchase an automobile. My husband has the use of a company van, but even that is rarely used. The difficulty comes when we want to go anywhere as a family. The work van has only one bucket seat in the front that fits three people. Obviously this presents difficulties. Even on our Saturday shopping trips with my mother-in-law, I end up sitting in the back of van; a solution that is both dangerous and illegal for the children. About a year ago, when I was working full-time, we were seriously considering buying a vehicle. But in the end, we thought the expense was too much when you consider not just payments, but insurance, road tax, maintenance and gas. Instead, we signed up for StreetCar; a car rental scheme that you pay a monthly fee to join and an hourly or daily rate only when you need to use a car or van. Looking back, that was one of the best decisions we have made both for the environment and family finances.

The other obvious example I found of reduction was our decision a year ago to switch to bags for life. We now have a stack of them beneath our kitchen sink and faithfully use them for our Saturday shops. But I do admit to occasionally forgetting them when just running out to grab something quickly. When this happens though, we make certain to re-use (we’ll talk more about that tomorrow) any plastic bags we get for outings or for small bin liners. Did you know that in the UK alone 100,000 TONNES of plastic bags are thrown away each year; that is the equivalent of 70,000 cars? So if there is one thing, I can encourage you to do, it is purchase bags for life. My store sells the sturdy plastic ones for about forty pence, the jute ones are about a pound, and the pretty cloth ones are about three pounds with a portion of the proceeds going to charity. Or it is very simple to make your own if you sew.

Speaking of which, sewing and mending our clothes is another excellent way of reducing. My boys from my husband to my sons are always wearing holes in their jeans on the inside thighs. Before the economic downturn, I admit we were likely to just toss them out and purchase new ones. But since I have not been working, we have instead taken them to the drycleaners and had them patched. The cost of the repairs is less than the cost of purchasing new (although I am committed to mending them myself from now on…a further savings). And we have reduced in a very small way the demand for jeans.

Of course, as I sit at my desk in my bedroom I am witnessing another reduction…the daylight streaming in through the open curtains. One of the first things I do each morning is open the curtains and the blinds. By using natural light when and where possible, we are reducing the amount of electricity that we consume and that the power grids must generate. We are also of course saving money on our bills. My husband is a genius at this; going around and turning off and unplugging everything he can each night before bed. I admit though that being American this whole switch on the plug thing still gets me and I often forget to do that, but I am improving. Of course, another example was turning down our thermostat during the winter and wearing heavier layers of clothes instead. In fact, I can think of only a couple of days this winter when we turned our heat on before night fall at all.

These are just a few ideas of ways that our family is reducing. There are many other things that we and you can do to cut back on the things we consume and help save our earth’s precious resources. On Friday as I said, we will do a mini-inventory and I will commit to new ideas on how our family can better live the 3 R’s reduce, re-use, recycle. I will be especially focusing on reducing since this is the most important of the R’s.

Green Technology of ISAAC 2008

China also needs to get on board.

Our world is facing a huge crisis today in the form of global warming. Though most recognize that it is a bomb ticking away and awaiting to explode, few of us actually make an effort to change this dangerous trend. Lots of research and methods are being discovered and discussed but very few concrete steps have been taken yet. The major culprit is the industries that contribute maximum carbon dioxide and other dangerous gases to the environment. Although it is imperative that each of us do something to reduce our carbon footprint on earth, the industries and huge factories in the developing worlds should be forced to take up real concrete methods of curtailing pollution.

With rising population, the world has to increase production of materials and goods for all. This obviously calls for more and more industries in the world, which will only add more emitting pollutants to the atmosphere. The world needs to come together to work out solutions that can both save the environment and maintain economic development.

The problem of global warming represents a serious threat to the entire world. We are running out of time as warned by many scientists around the globe. People have created this problem by greatly increasing the greenhouse gases in the atmosphere; and people working together will be the only way to stop it.

As President Obama makes an effort to introduce and promote green enterprises and industries, he will face a startling fact. Most pollution is created by China and the developing world. So no matter how much the developed world reduces their carbon emission, countries like China will compensate it with more pollutants. The per capita emission has increased six times today thanks to industrial projects which do not follow minimum environmental laws and directives.

It is imperative that Chinese President Hu Jintao and the other world leaders start to outline a plan now that will be followed by most countries, particularly China, in going green in their business practices.

However, the problem facing the world is that if we tackle this problem from a micro level, we come face to face with industrialists who are trying very hard to make their business a success and increase profit. There is nothing wrong in that because more profit would mean greater investment and a stronger economy. But most of these factory/industrial owners do not take into account the bad effects of pollution due to the emissions and discharges from their units.

Scientists across the globe are insisting that the environmental costs should also be included in the production costs. But, unfortunately, the busy industrialists do not have time to take into account the social and environmental responsibilities of the company; and, hence, little to no effort is made by them to alter the situation. Forcing the overworked staff to look into ways to follow the green norms is not cost effective in the long run.

A better way to tackle the problem is to hire a Green Consultant. The Green Consultant would look into individual business practices and suggest concrete methods to reduce pollution and reduce wastage and improper use of resources. For a nominal fee the consultant would work throughout the year to move the business toward a successful GCI Green Building certification. However, because businesses differ in nature, region, demands, budget, etc., it would make sense that one approach for all may not work well.

Consult the Green Business League website to learn more about the consultant and their expertise.

CO2 Footprint of a Product

We’ve certainly seen quite a few companies come out and say that their manufacturing facilities have a zero impact on the environment, meaning zero footprint, but indeed, there is much controversy on how to determine what a zero foot print is. It’s almost impossible to get to zero, even if a company goes and plants 10,000 trees over the course of 5-years.

The other day at a Think Tank meeting, we were talking about how to establish a complete CO2 discharge chain of a product, including all its components in the process of making it. From the wrappers, card board box, printing, assembly, energy to do all that, the distance the people traveled to work in what type of cars, etc. I mean really narrowing down the actual discharges.

Not because we are Global Warming alarmists, but because we feel it is not exactly correct for a company to claim Zero Emissions. And that we must have a more realistic view of the total process, Supply chain and all.

Many companies like Dell in Texas have stated that they have finally achieved zero emissions, but they were attacked for stating that, why? Because, everyone has a different concept of what nothing is. In other words we are all out there fighting over nothing and that makes no sense to anyone, no matter how you figure it.

Indeed, we should be applauding Dell for their solar panels, LEEDs certified warehouses and assembly plant and all their hard work and meaningful dedication to do the right thing. And yet, we are not doing that are we? Instead we find people attacking businesses, even those that go out of their way, spending millions of dollars to do the right thing. I ask are we doing the right thing by allowing persnickety environmental complainers to attack America’s greatest companies?

Gasification Sees a New Dawn

If you search for gasification and terms like “wood stove” on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.

So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?

What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.

This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.

Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.

Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.

These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.

Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.

Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.

Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.

Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.

Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.

Common Policies For Common Good

Concerns about dangerous climate change and large biodiversity loss are visible throughout the world: unprecedented rates of temperature increases and species extinctions are a reality. In 1999 Dr. Peter Raven, president of the International Botanical Congress, published a paper in which he states that “current extinction rate is now approaching 1,000 times the background rate and may climb to 10,000 times the background rate during the next century, if present trends continue. At this rate, one-third to two-thirds of all species of plants, animals, and other organisms would be lost during the second half of the 21st century, a loss that would easily equal those of past extinctions”. He then outlined seven “Points to Slow the Extinction of Plants”, including financial and capacity building instruments to help developing countries protect 80% of the world’s biodiversity they host. As far as climate change is concerned, the responsibility of developed countries is high in providing the most threatened regions in the world with good instruments to cope with this challenge (or at least examples of them to implement autonomously).

Climate change plays a significant role in this human-induced mass extinction because it is increasing the already large biodiversity losses caused by habitat destruction and fragmentation, water and air pollution, introduction of invasive species. Marine ecosystems will be affected by an increase in sea temperature, but also by ocean acidification, because of the higher concentration of dissolved carbon dioxide (carbonic acid): in fact this reduces the shell formation ability in many organisms. Polar (and mountain) ecosystems are particularly vulnerable to climate change, with effects such as thawing permafrost, decreased snow cover, losses from ice sheets and changes in ocean temperatures. Large impacts on Arctic biodiversity are already evident, pictures of polar bears wandering lost on small icebergs being a scary and sad symbol of the era we live in (even former U.S. President Bush, at the end of his mandate, recalled this image to show his fellow citizens he cared about climate change …)

In this rapidly changing environment it is therefore extremely important that conservation plans include adaption measures for ecosystems accordingly to the predicted regional climate patterns (but models need still to be improved a lot at this scale): dynamic approaches are needed to set good options for future ecosystems and landscapes. It will be necessary to facilitate the movement of species to new geographical locations, as they follow the shifting habitats.

The public concern is growing: in Africa last 28 February young people organized a march from impoverished urban areas to the summit of Mount Kilimanjaro to raise awareness on climate change, together with the Kilimanjaro Initiative and the UN’s global UNite to Combat Climate Change campaign. It seems though that the global attention on climate change doesn’t fully consider implications for biodiversity yet: while the negotiations and speeches on climate issues are very popular (and the Nobel Prize was awarded to the entire IPCC together with Al Gore in 2007) the meetings and decisions of the Convention on Biological Diversity (http://www.cbd.int/) don’t raise comparable interest. Is it because the anthropocentrism is (still) the prevailing philosophy and animals and plants are mainly seen by people as beautiful “supporting actors” on the planet we live on? Right when we are losing control of the global situation it is probably time to reflect on our role of dominant species and acknowledge the fundamental contribution of other organisms to our livelihoods, despite many of us live in the so called Technosphere.

Policies to protect the climate avoiding irreversible effects on the ecosystems need to be strongly interconnected with conservation strategies: preserving natural areas while helping them adapt to the changing climate means hopefully to leave better, or not as compromised, ecosystems to future generations. Climate and biodiversity, though ever changing and evolving, are common goods and they need common policies: if we reduce the human Ecological Footprint both the atmosphere and the biosphere will be better off (and our children and grandchildren living in them).

The Ecological Footprint is a measure of human demand on the Earth’s ecosystems. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. Using this assessment, it is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle. For 2005, humanity’s total ecological footprint was estimated at 1.3 planet Earths – in other words, humanity uses ecological services 1.3 times faster than Earths can renew them.

In Houston, LEED Schools Get More Than an E For Effort

We send our children to school every day and ask them to learn. They are, after all, the future of our world; and so we ask them to learn about right and wrong, learn about the world, and learn how to take care of each other. But do we want them to learn how to take care of the world, too?

That is what LEED Green Building schools in Houston and around the nation are doing. They are teaching the children, through example, what it means truly to earn an A for awareness of the environment’s needs. They stand for the future of America as a benchmark of creation care.

LEED Green Building schools are K-12 schools that are tailor-made to produce an environment safe and healthy for children, comfortable for teachers, cost-effective for the taxpayers, and easy on the environment. By addressing the uniqueness of school spaces and children’s health issues, LEED for Schools provides a unique, comprehensive tool for schools that wish to build green with measurable results. The rating system addresses issues such as classroom acoustics, daylight and views, mold prevention, and environmental site assessment.

In addition, Green schools cost less to operate, freeing up resources to truly improve students’ education. Their carefully planned acoustics and abundant daylight make it easier and more comfortable for students to learn. Their clean indoor air cuts down sick days and gives our children a head start for a healthy, prosperous future. And their innovative design provides a wealth of hands-on learning opportunities.

No longer must they learn through books about environmental safety and/or green projects around the world. Instead, they can learn hands-on at school – through observation and through practice.

Houston has taken the lead around the nation in building green schools. The Houston chapter is dedicated to showing school district leaders how the LEED FOR SCHOOLS process can benefit them. Other leading organizations in the area are also committed. Earlier this year, the Houston-Galveston Area Council joined with the Houston chapter to produce a year-long symposia to educate the public and educators about the facts and costs for LEED FOR SCHOOLS.

They ideally will have all their schools “Go Green” over the course of the next 10 years.

Other cities are following their lead. Salt Lake City, Grand Rapids and Seattle are all among the top cities with at least three green schools. And more are being built monthly. Both students and parents, teachers and administrators see the need and the benefits for green schools, and are lobbying for all school to change their ways.

For students and teachers, green schools mean reduced incidence of asthma, decreased absenteeism, improved academic performance and increased teacher satisfaction. For parents, green schools offer the confidence that comes with knowing their children spend their days in an environment that is both healthy and conducive to learning.

Green Schools get more than an E for effort. They are the bright and healthy future for our children.

How to Address Contaminated Land Issues

Under the relevant European Directives, an Environmental Statement is the formal product of an Environmental Impact Assessment. Environmental Statements are often organised in a way that describes the environmental baseline, mitigation and effects for each type of environmental receptors: ecology, water resources, archaeological resources, human beings etcetera. Contaminated land is often managed in the same ways as the various environmental receptor groups, although it is principally a cause of impacts rather than a receptor. It also often refers to a pre-existing condition and its damaging effect is on a variety of different receptors such as human health, structures and buildings, surface water features, groundwater features and ecology. This often means that land contamination specialists struggle with integrating the issue in a logical manner in an Environmental Statement. Sticking to the structured approach of an environmental statement is essential to ensure a clear description of the existing environmental condition, the potential impacts and the actions taken to avoid, minimise, offset or manage the impacts. This article is based on UK practice and legislation, although fundamentally the issues should be similar within other contexts.

Contaminated land is in many countries considered on a source-pathway-receptor basis. This is important to understand the impact land development can have on the issue of contaminated land. Development can interfere with any of these three elements. It can introduce sensitive receptors by changing the use of land, for instance by building new residential units on a site that was previously used for heavy industry. New pathways linking pre-existing contamination with an existing receptor can be formed, for instance when piling through a non-permeable layer connecting a layer of contaminated soils with a deep aquifer. Finally by introducing pollutants on the site a development project can introduce a potential source of contamination.

The second element to consider is the structured approach of an environmental statement. Apart from the introductory and procedural elements described in the environmental statement, a good environmental statement comprised the following sections:

• environmental baseline conditions
• potential environmental impacts
• mitigating measures
• residual environmental impacts

There should be a logical relation between the different sections. Any receptor that is affected and described in the section about the potential impacts and effects should have been introduced in the section describing the baseline. Any material impact should be assigned a mitigation or management action etc. Implementing this structure allows a clear description and understanding of the environmental impacts and the way it will be managed.

Applying these principles to contaminated land will result in a baseline condition section that describes the current sensitive receptors that are present within the potential sphere of influence of the development, the sensitivity and importance of these receptors, the presence of any pre-existing contamination and the presence of actual and potential pathways. The next section, potential environmental impacts or effects, first considers the impacts that the development will have in terms of the introduction (or removal) of sensitive receptors and the creation of new pathways between existing and potential pollution sources and receptors. In addition this section will describe the potential environmental impacts that are associated with the introduction of new sources of contamination. In the third section, mitigating measures, a description of the actions to mitigate each of the impacts that may occur should be provided. Finally a statement of the residual impact of the development is provided in the last section: residual environmental impacts.
