Earlier, climate change was caused by natural events such as solar changes, volcanic eruptions, tsunamis and Earth’s orbital changes, etc. But ever since human civilization started developing, a lot has changed on earth. Big industries started being built. The humans of the 21st century have been bitten by the bug of greed. It is because of this greed that we humans started deforestation and excessive use of fossil fuels. It is because of us that pollution of earth and water has expanded. The first reason for climate change is the ruthless cutting of trees. People are cutting trees indiscriminately. He gets good profit by selling the wood. He is also using wood in the furniture of his house. By cutting trees, he gets good and sufficient space there to build a house and do farming. Today, a lot of problems are happening in the world due to climate change. People are facing floods. Today we are not even getting food grains properly. Both nature and humans are responsible for climate change. We have to make people aware about this.
