Nowadays mankind faces a lot of ecological problems. One of them is anthropogenic  influence of man on our planet. Urgent measures should be taken in order to stop people’s destroying activities. For example, people shouldn’t pollute the places where they have their picnics: they shouldn’t drop litter in the places where they have their rest. They should collect it and bring to litter containers. People shouldn’t waste electricity and water because their resources aren’t unlimited. Besides, the seas are now also in danger. Scientists claim they are slowly dying. People should pay more attention to recycling problems. They shouldn't throw chemical wastes into rivers and seas. Unfortunately, it is impossible to recycle everything we would like to, because of lack of recycling centres, but still there can certainly be done much more than it is being done today. If we convert old and unnecessary things into new ones we will save some resources.Thus we will reduce polluting air and water. We all can do something to keep our planet clean. We should only buy things we really need.We should avoid buying packaged goods. We should also recycle paper and metal. We should bring cans, glass bottles and other things into the recycling centres. People should stop cutting down forests everywhere in large numbers. On the contrary, they should plant more new trees every year. They should stop hunting endangered species.                                                                                                                             I think we could walk more or use more often bikes instead of cars, especially to reach our school, university or work in order to avoid numerous traffic jams, which are harmful for air.  It goes without saying that one of the worst habits is smoking. It also does much harm to the environment. The more people give up this harmful habbit, the better.  As I have already mentioned above, people can do much to reduce pollution of air, water and land. Let's begin with ourselves then the environment and the world itself will become better!
