Society is being civilized every time; technology is also being invented every day. Thus, human life’s quality has been developing. However, the increasing of environmental issues isn’t still solved, and one of the most important problems is the pollution. It’s defined, “Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms” (en.wikipedia.org). Many countries have a meeting annually to discuss how to decline and settle this problem. Many investigate of a lot scientists about the causes of the pollution are listed in statistics; the approaches are stated, but there is no specific solution to be united. There are three main causes of environmental pollution which are much mentioned; they are air pollution, soil contamination, and water pollution. Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible—that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution. Carbon dioxide, a greenhouse gas, is the crucial pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas. Carbon dioxide also damages the ozone layer. Soil contamination frequently occurs in field, or the zone near nuclear plants. Soil contamination results when hazardous substances are spilled or buried directly in the soil. Chemical pesticides, which are always used in farming, cause serious consequence. Additionally, the radioactive leakage from the...
