In the first place, pollution of the environment has become the biggest problem in today's society. People will not find clean water to drink if they do not do some work to keep the water clean. There would be no fresh air if every one in the city drives a car to work. More and more wild animals are facing the danger of extinction because of the shortage of habitats. There would be no more wild animals if people continue to destroy forests. Therefore, there are more basic things that governments should do such as keeping the water clean, keeping the air fresh, and keeping the forests intact.
