The night sky live All rights reserved The night sky in the World Satellite monitoring of the artificial night sky brightness and the stellar visibility The interest for the protection of the night sky from light pollution is growing every day. A global scale periodic monitoring of the situation is necessary. Nighttime images of the Earth at night have been obtained from the Defense Metereological Satellite Program (DMSP) of the US Air Force since early '70. The first global image was obtained by Woodruff Sullivan in late '80. These images only showed the geographic distribution of the sources on the Earth surface because the satellite detectors were saturated by the strong flux emitted by them and no quantitative measurements were possible. Since 1998 unsaturated data become available, allowing quantitative measurements of the upward light flux emitted by sources.

24. Guidelines For The Reduction Of Light Pollution Explains how light pollution can and is been controlled in Malta. Lots of links. LPAG is a part of The Astronomical Society Of Malta. http://www.maltastro.org/lpag/

Guidelines for the reduction of light pollution Introduction General guidelines Chapter 1 Chapter 2 Chapter 3 Security lighting ... Exemptions, Glossary and references The Maltese Islands possess a rich architectural heritage and a uniquely beautiful scenic environment. At night, outdoor artificial lighting has become an integral component of this built and natural environment. Thus it is important that such illumination is intelligently planned to complement this environment, is subtle and avoids overlighting, and provides a cohesive appearance for our cities and their neighbourhoods. Safety and security for persons and property are also of paramount concern, and it is necessary to recognise the importance of quality of light versus quantity. And in order to preserve and enhance the unique qualities of the Maltese Islands’ rural and urban neighbourhoods and their visual environment, it is essential to encourage the highest quality of outdoor night-time lighting through the adoption of lighting standards. This is further corroborated through the widely used British Standard BS 5489, which states that " Light above the horizontal should be minimised in all installations, as it is wasteful, can be intrusive, and increases sky glow

Our Vanishing Night Earth at Night - NASA image (click on image to enlarge) Erosion of the Night Sky from Light Pollution "I remember camping as a kid when we could see so many stars you couldn't tell one constellation from the next, and the Milky Way was a river of light". "It was so dark you could hardly see your hand in front of your face, and I saw my shadow on the ground from Venus!" The lucky ones among us have probably made these claims, but sights such as this are becoming increasingly rare. Only a generation ago, many could still see the Milky Way from their backyards. Unfortunately, the overuse and poor quality of modern outdoor lighting is fast destroying a valuable natural resource - a dark nighttime sky. The light pollution that results from this misuse is, however, the easiest of pollution sources to fix.

WATER POLLUTION AND SOCIETY By David Krantz and Brad Kifferstein INTRODUCTION Comprising over 70% of the Earth’s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would be non-existent: it is essential for everything on our planet to grow and prosper. Although we as humans recognize this fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate. In addition to innocent organisms dying off, our drinking water has become greatly affected as is our ability to use water for recreational purposes. In order to combat water pollution, we must understand the problems and become part of the solution. POINT AND NONPOINT SOURCES According to the American College Dictionary, pollution is defined as: “to make foul or unclean; dirty.” Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. When it is unfit for its intended use, water is considered polluted. Two types of water pollutants exist; point source and nonpoint source. Point sources of pollution occur when harmful substances are emitted directly into a body of water. The Exxon Valdez oil spill best illustrates a point source water pollution. A nonpoint source delivers pollutants indirectly through environmental changes. An example of this type of water pollution is when fertilizer from a field is carried into a stream by rain, in the form of run-off

I'm already a High School student! It's hard to have time to fix my site. Yes! It's almost done! Oh yeah. By the way. I don't know why the site loads so slow... dunno why. This is a project done by some 7th graders in Hong Kong, attending Hong Kong International School. This is a project we are giving to the world, because it is a subject that concerns all of us around the world. This is not only for our water pollution project, but for the world to know about. We have put this project together, to help animals, and the next generation, to have a better world. It is up to us students of this generation to look toward. This is a matter that has been going on for years. Why do people say, "A better environment starts at home, but no one is cooperating to help this matter." So as you go through our project we hope you will reflect and do things to help this world, to become a better environment.

Air Pollution When people think about air pollution, they usually think about smog, acid rain, CFC's, and other forms of outdoor air pollution. But did you know that air pollution also can exist inside homes and other buildings? It can, and every year, the health of many people is affected by chemical substances present in the air within buildings. A great deal of research on pollution is being conducted at laboratories and universities. The goals of the research are to find solutions and to educate the public about the problem. Two places where this type of work is being done are LBNL and the University of California, Berkeley Let's take a closer look at the various types of air pollution , the effects that they have on people, and what is being (or not being) done to correct the problem.

35. Pollution pollution and Society by Marisa Buchanan and Carl Horwitz. pollution in our world effects two essential aspects of our planet air and water. http://www.umich.edu/~gs265/society/pollution.htm

Pollution and Society by Marisa Buchanan and Carl Horwitz Pollution in our world effects two essential aspects of our planet: air and water. Although their pollutants are emitted in completely different ways, they both harm living organisms. Air pollution is predominately emitted though the exhaust of motor vehicles and the combustion of fossil fuels, whereas water pollution is the result of industrial waste and environmental accidents. Our society knows that pollution is harmful and a serious problem for Earth but generally people don’t care. Nevertheless everybody needs to contribute to prevention and pay attention to government control in the amount of material large industries can emit into the air and/or water. Industry gives off a good share of the waste that is polluting our planet, but it’s every person is contributes as well. Government involvement is key to regulating toxins, building waste systems and protecting air and waters. Air Pollutants The earth’s atmosphere is composed primarily of nitrogen, oxygen, argon and carbon dioxide (the major components) as well as neon, krypton, helium and methane (the most predominate of the minor components) it is these gases which make up the 5.6*10 ton "shell" that surrounds our planet. However, humans, animals and vegetation in the Unites States alone emit 264 million tons of substances into the atmosphere each year. On a worldwide scale that turns out to be approximately 6.6 billion tons. These substances, which aren’t naturally part of the atmosphere, are called pollutants. Over ninety percent of all air pollutants can be divided up into five categories: carbon monoxide, nitrogen oxides, hydrocarbons, sulfur oxides and suspended particulate matter. Mass is only one way of categorizing pollutants. Substances can also be looked at from an effect stand point. For example, carbon monoxide (CO) comprises 56% of all air pollutants when looked at in terms of total mass. However, when looked at in terms of effect, CO makes up only 2.5% of the pollutants. In contrast, hydrocarbons make up 13% of all pollutants when look at in terms of mass but that number jumps to 71.5% when looked at from an effect point of view.
