We will desalinate. We will tap deeper into the Earth. However, the better we use what's already naturally available, the better by far.
Less than 3% of all water on Earth is fresh, and even that is mostly trapped in glaciers and ice caps. The stuff that's left in liquid form - in rivers, lakes and underground aquifers - only amounts to about 0.5% of the total water on Earth. And that tiny amount has to be shared by a steadily growing global population. The UN estimates that by 2050, half of the world's population may not have safe access to fresh water. So we should start saving right now, and it's not just about short showers and low-flow toilets. Watch the video to learn what you can do to help solve the global fresh water crisis.
