The protection of environment ( a graph composition) At the first glance at the picture,，so a large number of ships to catch fishes that until recently less and less fishes live in the sea. .However, less as the fishes are people disregard the phenomenon for they are in the pursuit of interest. we can't deny the fact that the biological cycle between nature and human has narrowed.And this proved painful.Not only people pursuit profit from the sea ,but also from the forest , land ,sky .Quantities of animals are going to be extinct.Trees on the mountain are hacked down . With the development of cities,many industries emit gas to the atmosp-here which has become polluted one.Thus ,nature gets revenge on human in turn.It rains acid rain and the sea level has been rised that threatened the coastal cities and people who live in there. All of these caused a crisis of pursuiting profit.We should begin to believe that the imporatance of the nature we live in ,and that protection meaures must be taken immedi-ately. Firstly,government should take the lead to encourage people to protect environmen--t and publish relevant policies about it. Secondly ,social supervison is great importance ,th--ose who are against the law should be responsible for their behavior. Thirdly, to enhace in-dividual qualities and to learn informative knowlege for protecting environment . Human liv--e in harmony with nature is not a golden memory.
