Global warming is now going to be a world wide disaster.Here in this post i will highlight the causes and effects of global warming.
Man is both creator and destroyer of environment.Man is the only reason behind the creation and destruction of environment. Destruction like deforestation caused by destructible activities of man in increasing day by day due to increase in human population.
What is Global Warming?
Global warming is one of the hazards caused by human activities like burning of fossil fuels global warming or green house effect that is causing a constant rise in temperature of Earth’s atmosphere or warming of earth’s atmosphere due to absorption of heat radiation.
Global Warming Causes
There are number of gases such as CO2, Methabe, CFC, Ozone etc, known as Green House Gases in atmosphere which absorb heat and infrared rays.Though these gases are also helpful in maintaining earth’s temperature by acting as a blanket around the globe yet an increase in concentration of CO2 and other gases by burning of fuels etc results in depletion of ozone layer which absorbs most of the harmful UV Radiations coming from sun which can cause disease like Skin Cancer.
The most concerning ozone depletions was observed in1987 where 50% of the Ozone was lost.This Ozone layer is very important for the existance of life on earth. We can say, if the ozone layer disappears completely then all the harmful ultraviolet rays coming from the sun would cause skin cancer in men and animals,and can also substantially damage plants.
Global Warming Effects
Change in Climate:
A continuous increase in green house gases leads to rise in global temperature and hence effects the climate like change in rainfall and shortage of water due to evaporation.
Due to change in climate,crop is also affected and reduced in production of rice,wheat and other crops.
Melting Of Glaciers:
High rise in temperature on Earth leads to submergence of islands and coastal areas.
Green house gases like CFCs etc, also cause ozone depletion.
Green house effects can also be seen in the rampant disturbances to the food chain and destroy many cold habitat species.
