Humans participate in the destruction of species habitats in numerous ways. The habitats are normally destroyed to benefit humans in one way or another. For instance, we drain swamps or fill them so we can build houses or parking lots or anything we want to benefit us. We cut down trees for limber to build houses, and other buildings, also to benefit us. Sometimes we are even destroying species habitats without even realizing it. Every time we drive a motor vehicle sulfur and nitrogen oxide is released into the air creating acid rain, which destroys forests and contaminates lakes and streams making them uninhabitable because of its highly acidic precipitation.
Global warming is also contributing to the factor of the extinction of species. Carbon dioxide and other gases are released into the atmosphere by the burning of fossil fuel such as oil, coal and natural gas. The atmosphere is trapping heat there creating the green house effect. The greenhouse effect is the term for the role played by the atmosphere in maintaining higher temperatures near the earth's surface than could exist if the atmosphere were not present. Global warming could increase an average temperature by three to eight degrees Fahrenheit by the year 2050. The higher temperatures will disrupt the biosphere to a great extent. It will raise sea levels, making species more vulnerable to diseases and altering habitats. This will threaten numerous species therefore causing them to migrate in order to survive.
Humans also pollute the earth in many ways. Humans liter all the time. When driving down the road, instead of putting trash aside we just throw it out in the window. Whether it's just a gum wrapper or a cigarette or it is a drink cup. Animals will then go and eat it and it can get stuck in their throats and it kills them. Big oil companies will just dump oil into pond or rivers there by polluting the water and killing thousands of species that live in the water.
