ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil

Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water poll
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may rise a predicted from 2 to 6 degrees Celsius. This may not seem as much but with the Earth's delicate balance we will have lost several

Environmental Issues and Sustainable Development in Estonia We are all a part of the environment that surrounds us. Unfortunately, people do not always know how to take care of the things that are vital to our survivor but what we take for granted such as water, air and forests products. However, things have improved in recent years. What has been done to improve the environment in Estonia? People today are too lazy to think or to do something to protect the environment. They dump their waste into forests and even rivers which causes air and water pollution. Fortunately, people have come up with different organisations and events to help clean our envrionment. An annual event such as ,,Teeme ära!" motivates people to go out, spend time with friends and family and have fun while cleaning up the trash. This event first took place in 2008 and is now one of the biggest worldwide environmental events. Estonian Commission on Sustainable Development is one of the organisations that is
Environmental issues in Estonia The Earth is considered to be the most beatiful planets in the Universe. But our planet is threaten by environmental problems. Even a small country like Estonia can make difference. Our capital city is fighting against air pollution. But people produce much refuse and ways of recycling are getting old. Water pollution is also a problem in Estonia. We have factories that let their waste run into rivers. One of the biggest problems in Estonia is air pollution. Our air is polluted by exhaust fumes, because today we have a lot of cars, buses and other machines. In 2009 we had 407 cars to thousand inhabitants, which is lower than European Union average, but this number is still high. Because cars produce gases that contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the greenhouse effect. Tallinn wants to fight against it by offering public transportation for free, to Tallinn citizen. So that people wo
