Concepts Used:
Environmental Pollution
When there is an unpleasant change in the surrounding that has harmful effects on plants and animals, it leads to environmental pollution. Pollution is the root cause of a substance - “pollutant”. We can have pollutants in solid, liquid, or gaseous forms. A substance becomes a pollutant when its concentration is greater than the natural abundance and this increase in concentration is either because of human activities or natural phenomena.
Effects of Environmental Pollution:
Some pollutants are scraped into the soil by human beings. This leads to air, water, and soil pollution. If the soil is polluted, the helpful or functional microorganisms in it will die and the fertility of the soil will vanish. The production of crops will diminish. If the soil is not fertile; it will have a harmful consequence on human society.
