As is known to us all,our environme

As is known to us all,our environment is getting worse and worse.There has been an increase in the amount of CO2 in the atmosphere,which,in turn,causes global warming and greenhouse effects.And the CO2 are let out by power generation using coal or oil,numbers of gasoline engines-cars,trucks,etc and the growth of industrial production.In order to protect our environment,we should live a low-carbon life.

First of all,when we go out,we should take a bus or ride a bike instead of driving a car.Cars not only let out carbon dioxide but also waste energy. Second,we had best not use plastic bags which can bring about the white pollution.We should use the environmentally friendly bags.Third,it's of great use to plant trees.Trees can absorb carbon dioxide and release oxygen.Finally,we should start with small things,Therefore, as students, we ought to turn out the lights the moment we leave,turn off the tap in time,and reuse our textbooks and so on.
