with the fast pace of economic development , the environment problems are more serious . for example : some rivers were polluted , some animals and plants were extinct and global warming and so on ........ i think it is every citizen's duty to work hard to build a " harmonious society ."
as members of society , what should we do ?
first of all , we should be friendly with the nature . then we can encourage people to plant more trees and drive less cars in daily life . we are responsible to protect the animals and plants and save energy . as a high school student , at prsent , the most important thing for me is to make a contribution to our society by studying hard and learning to be a good citizen .
let's take action at once !
