The average temperature of the earth is about 15-22C. But in recent times, the average temperature is increasing due to various reasons which may include- Greenhouse effects, extensive deforestation, burning of fossil fuels, changes in climatic pattern, atmospheric changes etc. The activities that are responsible for global warming include burning of fossil fuels which contain different gases that are acting in Greenhouse effects, cutting or clearing of forest areas that have significant role in the regulation of global temperature. The effects of global warming will be very dangerous to all living organisms. The effects are- melting of ice and glaciers, sea level rise, ecological balance disruption, affecting world food and agricultural production, decrease in biological productivity, increase in breeding of pests and diseases, severe and intensive tropical storms etc. Scientists believe that if we cannot stop global warming, we will have to face many problems which may lead to the extinction of different flora and fauna. Human beings will also suffer badly. So, we must stop global warming by all means for the survival of human being as well as other living beings in the planet earth. The steps and programmes that must be taken immediately are- Conservation of forests, extensive afforestation, encouraging community forestry, reduction in burning of fossil fuels, development of environmentally compatible technologies, effective check on the growth of population and imparting formal and non-formal environmental education. Thus we can ensure a better planet and environment for the present generation as well as for the posterity.
