Dear friend, Hi, how are you? I am fine. I received your letter by getting a solution to decrease the world temperature. In my opinion, the decrease occur in world temperature if we reduce the emission of carbondioxide gas that is releases due to burning of fossil fuel in industries and vehicles. We have to use electric vehicles in order to reduce carbondioxide gas emission as well as planting more trees because trees absorb carbondioxide gas and helps in cleaning the environment. I hope this answer will help you to understand the solution. We will meet soon.
