The are many problems which are threaten our natural environment Acid rain , global warming and air and water pollution are among the most serious ones. There are several ways to help improve the situation. Firstly , we should encourage recycling , because it is the production of new materials which causes the most damage. We must learn to reuse things like plastic bags and glass jars. Secondly , driving an environmentally friendly car is also helpful. Furthermore , joining an organisation which plants trees or clear up beaches would be proof that you are really concerned about the environment. Lastly , supporting groups such ad Greenpeace , which try to prevent many environmental disasters , would help to ensure that our planet will be clean and safe for future generations
