Water Scarcity Solutions

This week in science we have been learning about water scarcity. We got into groups and tried to come up with reasonable solutions. My group said that we should use salt water in toilets instead of clean water, because the clean water is going to waste and we have plenty of salt water. We are running out of clean, fresh water. Here are some solutions that scientists have come up with. Our idea is original so no one has come up with that solution but here are a few solutions that scientists have come up with
One of them is play pump. So what happens with Play Pump is that there is a merry-go-round and when kids play on it it will pump water out of a tap. It sounds very cool and a very easy to do.
