The hotel wishes to save the world's natural resources(资源). Every day, tons of detergent(洗涤剂) and millions of tons of water are used to wash towels(毛巾) which have been used only once.
Here's how you can help:
A towel on the rack(架子)means: "I'll use it again."
A towel on the floor means: "Please change."
