Dear friends，
As we can see，the environment around us is getting worse and worse．

Our life and health have been affected greatly．The earth is our home and we have the duty to take care of it，not only for ourselves but also for our future generations．（高分句型一）Fortunately，more and more people have become aware of this problem．Many effective measures have been taken to deal with it by the government．（提出倡議）
