With the development of science and technology,global warming is becomingthe focus of human beings.Some measures should be taken to protect ourplanet.
To begin with,it's essential to save energy because of limited naturalresources.For instance,turn off water tap after washing hands and turn offlights immediately if there is no person in the room.What's more,we'd better goout on foot or by bike,instead of using vehicles in order to reduce carbonemission,which is also good to our health.Besides,we are supposed to reducewaste,and reuse what we can be recycled.Plus,no littering and planting moretrees are good ways to beautify our environment.
In a ward,the earth is our only home.we should take immediate action toprotect it.Whatever you do,no matter how small itis,counts!
