The Green School Project has become part of the environmental education in our school .However , there are still a lot of problems in the school .

Very often you come across an empty classroom with the lights still on . It’s not difficult to find evidence of wasting water , a very serious problem . Additionally , students do not recycle enough , throwing away the soft drink bottles , used exercise papers and books .Worse still , many students still use the non-environmentally friendly lunch boxes , causing the ‘White Pollution’ .

These things show that many students lack the sense of environmental awareness . It’s important to educate students to be more environmentally friendly . At the same time , students can do small things , such as collecting used items for recycling , turning off the lights , saving water . Always remember that it’s everyone’s responsibility to protect the environment .
