At present,what the biggest environmental problem human beings are facing is the global warming.What causes it is that the greenhouse gas emission is increasing rapidly.As a result,the sea level is rising,which may be harm to some offshore countries,and the natural disasters frequently happened.
SO,why don't we take some action to improve it?Firstly,use clean energy as much as you can.Secondly,to walk to school instead of taking which is powered of petrol.Then,make full use of everything that seem to be litter like the used clothes,water,etc.Last but not least,urge the people around you to do the same thing as you.Unity is power,isn't it?
Let's heal the world and make it a better place.
do it yourself.
