About 50 to 55 years ago our nation was a clean and green nation with a number of plants, trees, forests etc. because of the demand of the wood many trees had been exploited after this period. trees were also harmed because of soil pollution, water pollution and air pollution...we can now also make our country look clean and green with a little efforts, by planting trees.
