One day, Mr. Rubbish, an English teacher, asked all his students a question, “What should we do for our Mother Earth at once, or our future will end.

The student thought for several days. They replied to Mr Rubbish, “We should recycle paper cans and glass. We should get off the grass. We should not waste water but save the power. We should get out the shower within 15 minutes.
