Don't let your tears be the last drop of water.
There is also a pot of green plants. Put a plastic bag on the mask and take it down. There is water in the bag. I'm telling you, this will lead to water, but it won't work.
Questioning the last resort of finding water, but this cartoon is to be made and presented to the city for exhibition.

If plants are used to produce water, at least plants must have water to survive.
