Our planet is facing big problems such as pollution, global warming, and a shortage of natural resources. Problems that have occurred because of people's actions. Firstly, I believe that we are fond of major global changes because of our weakness in evaluating our actions. Secondly, people all over the world, for the last decade, destroying the planet by cutting down forests, making big concrete cities, and using unconsciously all natural resources. Not only these but many more bad habits bring us to air and water pollution.
