Effects of environmental destruction include global warming, climate change, ozone layer depletion, land degradation and human disease. Environmental destruction occurs when events deplete the earth's natural resources. Its main causes are technological, institutional and socio-economic activities.
Emission of greenhouse gases to the atmosphere causes global warming. These gases, which include nitrous oxide, methane, chlorofluorocarbons and carbon dioxide, block heat radiated from the Earth. Global warming leads to flooding, soil erosion, drought and rise in sea water levels.
The ozone layer sits at about 20 to 30 kilometers above sea level. It provides a protective layer, which prevents the sun's harmful ultraviolet rays from reaching the Earth. Environmental destruction activities, such as chemicals, human activities, and the release of chloroflourocarbons to the atmosphere, trigger the depletion of the ozone layer. Ultraviolet rays lead to skin diseases, lower agriculture production and death of aquatic life.
Human activities that increase the levels of carbon dioxide and other heat trapping gases in the atmosphere trigger climate change. A rise in air temperature increases evaporation from bodies of water and affects marine life. It also degrades water sources.
Constant use of pesticides and insecticides results in land degradation. It makes the soil infertile and affects plant growth. Industrial chemical waste disposal also affects the quality of soil.
Environmental destruction causes various diseases that affect human health. For instance, air pollution causes respiratory problems, such as lung cancer and asthma. Air pollution also either directly or indirectly causes various cardiovascular diseases.
