1 min speech on environment for asl 9th cbse

Answer 1

Our environment is getting polluted day by day and human being are the main culprits of such degradation.We destroy forest in such fast rate that the forest which are considered as the lungs of the earth are disappearing.
This disappearance of forest leads global warming.Global warming is a state when the temperature of our earth's atmosphere increases gradually.This happens when carbon dioxide traps the heat energy it receives from the sun during daytime and don't release it and this then leads to melting of polar caps.The melting of polar caps lead to disasters like tsunami,flood,etc.It is believed by the scientists that the eggs of dinosaur which are believed to still exist in our will get incubated and hence hatch and the the Jurassic period will dwell again on earth's surface.
To eliminate such disaster a technology known as the green technology has come in life recently.The study involves techniques to get rid of degradation of environment.Besides green technology we can also contribute to make our earth best place to live by using vehicles which releases little amount of carbon-dioxide and limit the use of plastics.Plastics can't be eliminated completely so we should limit the use of it.Like these small contributions we cansave our environment from degradation.
