we should do everything to save water because it's vital to our lives. there're several ways for us to save water. first, we could always reuse water. for example. we could use the water after we wash the vegetables to water hte flowers. second, we could save some water in the tiolet by flushing it after 2 people had gone to it. third, we should promote the idea of saving water to everyone who could listen. then, please don't do something that'll make us regret later. don't let the last drop of water on earth become our tears.
