Water is needed big time and, as you know, water is a big problem for many people, so why not use water desalination and the planet’s abundant sea water? I am sure you have been told not to waste water by your parents and teachers. Women and children in many places have to spend a lot of their day going for water. We can’t imagine their life here. Agriculture is suffers because of a lack of water. Also with climate change water patterns are altering and people have to move away from their home land because of drought.
This student is asking a question to Bill Nye in the video below about desalination. Bill Nye is a great scientist and is insisting that people in all walks of life should try to become better skeptics, ask questions, wonder about how things work, why things happen. Desalination is the taking out of the salt in sea water. Sea water is in great quantity but fresh water (without salt) is way less abundant.

MIT students explain in this video the new technology using graphene Bill Nye talks about:
And here, Veritaserum Physics teacher explains how to make graphene. Very easy to understand and it makes water desalination closer to our reality.
Currently, here is what California is doing and it will give you an idea of what is happening here in a Western Country.
And here is a complementary explanation of the Californian Effort.
