There are so many causes for global warming and climate change such as deforestation, lack of fertilization. As a consequences, sea level is getting higher, ice-mountains are melting. I don’t think burning fuels are the main source of problem for climate change.The world population is significantly growing and need to make proper amount of products for them. To run industries smoothly, fuels need to be accessed easily, alternative energy like solar power takes lots of space and there is not guarantee that we will get sufficient energy in time. In rainy reason, it’s obviously clear that we won’t get enough energy for solar power.
