Question
Read the following passage, and answer the question.
Pollution is the introduction of one or more contaminants into the environment. These contaminants cause instability, disorder, and harm to the ecosystem (physical systems or living organisms). The major types of pollution are air, water, and land pollution.
Air Pollution
The pollution of air by pollutants such as dust, smoke, and harmful gases that cause adverse effects on human beings, plants, animals, and environment, is known as air pollution. Pollutants that pollute the air can be in the form of solids, liquids, or gases.
Human activities such as the development of industries, factories, automobiles, agriculture, power plants, and urban centers release hundreds of thousands of tons of pollutants into the air from various sources. The major man-made sources of air pollution are automobiles, industries, brick kilns, and the burning of garbage.
Water Pollution
Water pollution is the releasing of harmful substances and toxic materials into water bodies, causing an undesirable change in the condition of the water.
When untreated industrial waste, domestic waste, municipal waste, and agricultural waste are discharged, the inevitable result will be the pollution of the nearby water bodies.
Land (Soil) Pollution
Soil is a thin layer of organic and inorganic materials formed from weathering of rocks and minerals that cover the earth's surface. The formation of soil happens over a very long period, and it is an important part of the natural environment.
Human activities (anthropogenic activities) affect the soil quality directly or indirectly, leading to soil pollution. Thus, soil pollution is the destruction of soil quality due to the presence of different pollutants in the soil. The direct contact of contaminated soil may cause various health risks.
What is the main idea of the passage?
Pollution is harmful to living things.
Air pollution causes problems to lungs.
Water pollution causes problems to water bodies.
Soil pollution is the weathering of rocks.
