DOK Level 1: Recall

The major desalination plants of the world are generally located near the coast because

• the soil there is better for building desalination plants on.

• that is where there is a sufficient number of workers.

• it is cooler there which is required for desalination.

• desalination requires access to plenty of sea water.

How can desalination impact the environment negatively?

• By producing clean energy

• Through the release of brine into oceans

• By reducing carbon emissions

• Through increasing freshwater biodiversity
