In order to protect the beach, my company hold the activity to clean up the beach every year. We can collect around 50kg garbage from the beach. Besides, to protect coral reef and other marine animals, I don’t wear sunscreen when I go to the beach. On the other hand, due to global warming, I don’t turn on air conditioner all the time when I am at home. Even though I turn up air conditioner, I don’t make it too cool to try my best to reduce discharge of heat to the environment.
