Lets save environment from hazards and destructions caused by Global Warming...many things can be done individually as well as collectively to reduce the global warming impact by reducing carbon dioxide emission as it gets trapped in the earth's atmosphere and thereby trapping ultra violet rays of sun warming the earth's average temperature. by stop cutting the trees i.e. Deforestation, by using solar energy resources and its equipments, by plantings some more trees i.e. Afforestation as the trees absorbs carbon dioxide and gives out fresh oxygen to us, due to global warming many species like polar bear have come on the verge of extinction. Glaciers too have started melting which in turn rises sea level, when carbon dioxide is emitted directly in the water banks it destroys the ecosystem.........so many hazards are there but its our responsibility to make persistent efforts to save the Earth and Nature both have blessed us with gifts to survive this life...
