Earth - the only planet where life is possible - will it be possible in future too? We say we enjoy nature. So why don't we try and protect it from demolishing?? We all know that the smoke emitted from vehicles, refrigirators, air conditioners are creating hole in the ozone allowing the sun's harmful radiations to fall on earth. Greenhouse gases like carbon-di-oxide, methane etc. rise upwards and create a blanket around earth. Short-wave radiations from the sun can pass through this blanket, but long-wave radiations from earth cannot go through it. This results in the earth becoming warmer and warmer day by day. This heating is concentrated much near the poles, hence the glaciers at low altitudes may melt and cause rise in sea level due to thermal expansion of water. This entire process is called global warming.
What can we do to prevent global warming? We can't totally stop using vehicles or refrigirators. We can't live without them. But we can try to use public transport maximum. If our destination is not very far we can even walk. The heat produced from electrical appliances also cause global warming. We can try to switch off lights or fans when we are not using them. When we are downloading something in our computer which takes hours to complete, we can off the monitor alone. We can reduce using mobile phones much because in addition to global warming, it also affects our health. The harmful radiations from it can cause brain cancer or tumors. We must avoid talking in mobile when there is low charge in it, because it is then that the radiations are emitted more. It has the capacity to cause ear problems. Also the diwali crackers. Did any God tell us to celebrate a festival by demolishing Nature? No. We just fancy so. If anyone sees the smoke emitted from just one cracker, say flowerpot, he or she will become aware of the danger it is causing. If just a flowerpot emits so much smoke then they'll think how much a 100 wala or 1000 wala will emit.

Let us do our best to save earth and protect nature. Let us celebrate festivals by praying and performing poojas but not by annihilating Nature. We can recycle paper, and help to avoid cutting down of trees. Pollution should be avoided to the maximum. This is our earth. We ought to save it.
