Today, many buildings collect rainwater and then use it in various ways, such as giving water to plants. Do you think such buildings will become more common in the future?
I think many buildings will collect rainwater in the future.I have two reasons why I think so.
To begin with, collecting rainwater makes buildings little cost to use water.Buildings can spend more money instead of water cost.
In addition, collected rainwater may help us when a disaster happen. For example, collected rainwater can boil food and be used for taking a bath.
For these reasons, I think It will become more common that buildings collect rainwater in the future.
