What are the environmental problems of our planet?

Every year our planet is more and more exposed to pollution from human life. Plants are massively built that pollute the air, many cars produce carbon monoxide, tons of garbage fall into water bodies and kill the entire underwater world. The ecological state of the planet is not satisfactory. People pollute the land, water, cut down forests and destroy endangered species of animals. all these activities have a very detrimental effect on the ecological state of our home planet.
