Earth Day

On April 22th ,it's an important day for us ,it's ''Earth Day'' .Now , our earth is getting worse every day . Air pollution as well as water pollution is everywhere , and the glacier is melting . The poor polar bears have no home to stay ! Also , the ozone layer is broken .The global warming is serious day by day .It's very scary! What can we do? We can't just watch indifferently . We must do something .Although we are just students , we can pick up garbage,recycle,reduce waste , reuse old things , save electricity .Maybe it's  just a simple action , but it can help the earth a lot.Don't think that a good deed is so small that it is not worth.Many a little makes a mickle. Let's do it to help the earth!!
