A variety of environmental problems now affect our entire world. Some of the largest problems now affecting the world are Acid Rain, Air Pollution, Global Warming, Hazardous Waste, Ozone Depletion, Smog, Water Pollution, Overpopulation, and Rain Forest Destruction. Every environmental problem has causes, numerous effects, and most importantly, a solution. There are separate pages discussing each of these topics for every major environmental problem covered in this section.
Air is the ocean we breathe. Air supplies us with oxygen which is essential for our bodies to live. Air is 99.9% nitrogen, oxygen, water vapor and inert gases. Human activities can release substances into the air, some of which can cause problems for humans, plants, and animals.
The rainforests are dying,.rare plant and animal species are disappearing, crops are failing to grow, people are dying of hunger and the air is being polluted. It's time we woke up to these problems and started repairing the damage.
Another big problem is water pollution. Water pollution can be defined in many ways. Usually, it means one or more substances have built up in water to such an extent that they cause problems for animals or people. Oceans, lakes, rivers, and other inland waters can naturally clean up a certain amount of pollution by dispersing it harmlessly. If you poured a cup of black ink into a river, the ink would quickly disappear into the river's much larger volume of clean water. The ink would still be there in the river, but in such a low concentration that you would not be able to see it. At such low levels, the chemicals in the ink probably would not present any real problem.
Fortunately, it is not too late to solve these problems. So you will have the time, you protect the environmental. We can plant trees and adopt animals. Together save our planet.
