People are once again impressed by a recent science fiction movie. In the movie, people on a desert planet wear special suits that turn sweat (汗水) into clean drinking water. Sounds like magic? In fact, in some water-short places on Earth, people recycle waste water in similar ways. Even astronauts in space recycle their water!

You might think, “We have plenty of water on Earth.” But actually, clean water is limited. Some countries are developing better ways to save water. In Germany, there’s an amazing waste water reuse system. This new system separates waste water into different types.

— Rainwater is collected to water the gardens

— “Gray water” from kitchen and bathroom sinks is used to flush toilets.

— “Black water” from toilets is sent to a local factory to be turned into biogas (沼气).

The purpose of the system is not only to reduce water use but also to provide power for local people

Perhaps more countries can follow this example. The challenge lies with old houses. Using these new systems in old buildings costs a lot. However, people once thought LED lights were expensive too. Now they’re everywhere. This time, we can make similar changes to save water.

Remember, every drop counts! By using water wisely today. We can make sure there’s enough clean water for everyone tomorrow.
