Water scarcity - defined as the annual availability of less than 1,000 cubic meters of water per person - already afffects 40 % of the world's population. By 2025, this figure could rise to 66 % as a result of population growth, climate change and water pollution. What if we could turn seawater into drinkable water? We can. Desalination technologies have existed for hundreds of years, although the cost of it remains high. |
