Answer
The trapping of the earth's radiated energy by carbon dioxide present in the air so as to keep the earth warm is called the greenhouse effect.
Benefits of greenhouse effect are:
- In colder regions, this principle is applied to grow plants.
- It makes the surface of earth warm which provides a suitable environment for survival of living organisms.
Due to deforestation and air pollution, the total amount of carbon dioxide in air has increased. Carbon dioxide gas along with other greenhouse gases have created a thermal blanket around the earth, trapping more heat and increasing the greenhouse effect. This further warming of earth is known as global warming which is harmful. Global warming has serious consequences like:
- It will cause melting of glaciers and ice in polar regions causing floods.
- Ecological balance will get disturbed, rainfall patterns will be changed.
- Pattern of crop cultivation will be changed.
- Many species of plants and animals will get extinct.
