TRANSCRIPT: 

When was the first time we thought about the importance of water? During the ongoing Californian and Middle Eastern droughts? The famous Australian drought? 1850s? Before Christ? When?

Indeed, we were very smart. We got it from the very beginning as we developed our major civilizations around big rivers. Rivers like the Tigris and the Euphrates, the Nile, the Indus, and the Yellow.

Water is the most essential element of life. We need it for drinking and sanitation. We need it to produce food. We need it to produce power and cool our power plants. And we need it for maintaining our ecosystems services.

So what’s going to happen with the growing population? We already have problems with water. Not everyone has enough access to water. 15% of the world’s population lacks access to clean water. That number is 50% in Sub-Saharan Africa.

The modern people, the developed ones, are also changing their diet. Ironically, they prefer meat to vegetables, the unhealthy diet. That means 15,000 liters of water instead of 2,000 liters of water per kilogram of food. So to feed the 2 billion extra people joining us on this planet, we need to raise 60% more water. We’re already bankrupt. We don’t have that much water. We have to increase the water withdrawal by 50% in the developing world, and 18% in the rest of the world.
