Describe the effects of human activities in influencing natural ecosystem cycles with special reference to carbon cycle. |
|
Answer» Human activities have significantly influenced the carbon cycle. Rapid deforestation and massive burning of fossil fuels for energy and transport have significantly increased the rate of release of carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas which allows the solar radiations to enter but prevent the escape of heat radiations of longer wavelength. The absorbed radiations again come to earth’s surface and heat it up. Thereby increasing the average temperature of surface of the earth, i.e., global warming. |
