Pollution is unwanted for or undesired change in the chemical or biological properties of air, water and soil which is very harmful to human life, ecology and natural resources. Air pollution, soil pollution, water pollution, etc. are different kind of pollution that badly affects life on earth.

Addition of harmful substances in the environment is called pollution. Pollutants cause pollution. Pollutants are substances that spoil our environment. Air pollution, noise pollution are examples of pollution.

Pollution refers to the adding up of contaminants into the environment, by waste, chemicals, and other harmful substances. It has an adverse effect on living beings and on environment. It brings undesirable changes by making land, air, and water dirty and unfit for use. Human activities add pollutants to the environment. There are four main forms of pollution: air, water, land and noise.

Release of harmful substances into the air, water and soil, that has harmful effects on the living things is called pollution. These harmful substances are called pollutants. The main kinds of environmental pollution are air pollution, water pollution, soil pollution and noise pollution.

Match the following. 1 Sulphur dioxide Water pollution 2 CFCs Acid rain 3 Plastic bags Global warming 4 Agricultural runoff Ozone hole 5 Carbon dioxide Soil pollution

Sulphur dioxide is one of the main components of acid rain. CFC is responsible for ozone layer depletion. Plastic bags cause soil pollution as they fail to decompose. Agricultural runoff leads to water pollution. Carbon dioxide gas adds to global warming. 1 Sulphur dioxide Acid rain 2 CFCs Ozone hole 3 Plastic bags Soil pollution 4 Agricultural runoff Water pollution 5 Carbon dioxide Global warming
