A classification essay on page 144 (first draft)
Environmental pollution, which is caused by human activities which do production, transportation, daily life and so on, is a phenomenon that harms the natural or living environment. The pollution has been deteriorated rapidly after the Industrial Revolution and is top priority that should be resolved right now. It is often said that Earth's environment is composed of the atmosphere(air), lithosphere(soil or rock) and hydrosphere(water). According to these three components of the planet, the major types of environmental pollution can be sorted into air pollution, water pollution and soil contamination.
First of all, air pollution happens when overly many pollutants, which can harm humans or other living organisms, are released into the atmosphere. Common air pollutants are usually harmful gases, which are produced by industry and motor vehicles. For example, there are carbon monoxide, sulfur dioxide, chlorofluorocarbons(CFCs) and nitrogen oxides and so on. Serious problems caused by air pollution, are acid rain, stratospheric ozone depletion, smog, global worming etc. Actually, the atmosphere is essential to support life on the planet so, what harms it can threaten human health or life as well as the Earth's ecosystem.
The next crucial is water pollution because most of all, Earth is covered with water, amounting to 70 percent of its surface. Water pollution is caused especially when pollutants, intentionally or through spills, are discharged into water bodies like lakes, rivers, oceans and groundwater etc. Commonly discharged pollutants are wastewater from commercial and industrial waste; untreated domestic sewage; chemical contaminants like chlorine etc. In addition, water pollution is closely related to terrible sanitation problems; so, it has been suggested that it is the leading worldwide cause of deaths and diseases.
Another major type is soil contamination. It happens when chemicals are released intentionally, or by spill or underground leakage, into the natural soil environment. Common soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons etc. Soil contamination is serious in that it is the source of food or nutrition for almost all living beings on earth. Furthermore, it can destroy the entire ecosystem when pollutants mixed in the soil enter the food chain and spread around the planet. Soil pollution can also threaten the health of human or other living organism so, it should be always checked.
Environmental pollution is divided into air, water and soil pollution according to the sphere which pollutants is introduced to. Any type of environmental pollution can harm the overall ecosystem because almost all parts composing Earth's environment is closely connected. However, recovering the destroyed environment is extremely difficult because it is time consuming and expensive, requiring extensive knowledge and skills. Thus, we should make arduous efforts to protect our environment.
1. your main point seemed to be three major types of envrionmental pollution.
ReplyDelete2. I would like to know more about what kind of problems each pollution makes. I mean, something more specific is needed.
3. I particularly liked how you organized your essay. Each body paragraph has cause and effect of each pollution.
4. The name of many harmful substances is hard to know, so I think it is OK to leave out. Instead, please add some explanations about how this bad substances affect our lives.

Environmental pollution, which is caused by human industrial activities or daily life, is a phenomenon that harms the natural or living environment. The pollution has been deteriorated rapidly after the Industrial Revolution and is top priority that should be resolved right now. It is often said that Earth’s environment is composed of the atmosphere (air), lithosphere (soil or rock) and hydrosphere (water). According to these three components of the planet, environmental pollution can be largely sorted into air pollution, water pollution and soil contamination.
First of all, air pollution happens when overly many pollutants, which can harm humans or other living organisms, are released into the atmosphere.
