Earth vs. humans

When the earth began it was filled with gases and molecules. Then there was water, plants and animals and years ago man came. Through the years humans have evolved beyond our expectations, while this is exciting we have caused damage and deterioration to our environment. From the air we breathe to the water we drink and the animals we consume, the environment is constantly being affected. First the very stuff we breathe is being contaminated; the burning of fossil fuel, trash, gases, wood and chemicals is polluting our planet. These same pollutants are eating away at the one thing that protects us from harmful ultraviolet rays. The ozone is a layer in our atmosphere that is 50 kilometers thick. Due to CFC’s it has decreased to 3 percent. This then causes global warming which affects our climate. By burning fossil fuel we have increased the greenhouse effect, damage plant and soil life. Some pollutants absorb and fall to the earth as acid or weak rain. They are both harmful to the living. Glacier and snow caps melt, forcing the seas to rise. From there it just gets worse, longer winters, hurricanes that cause natural disasters and massive tornados on water. The climate changes and weather breakdown also effect animals. 550 million years ago the earliest plants were brown alga, kelp, and Precambrian they existed 350 billion years ago. Today there is thousands even millions of plant life, the temperature increase is cause the plants to relocate or even parish. When the migration of birds happens late, the ecosystem balance is un-natural....
