Serious stuff, here. Doom-n-gloom prophecies are often exaggerated, but there’s a lot of careful research behind this. We really need to face the fact that our way of life is not sustainable.
I do disagree with one statement made here: that the world eats more food than we produce each year. Nope – we throw away enough food to feed all the hungry people. And most of what we grow goes to feed an overabundance of animals that we then slaughter for food. This is highly inefficient and is wasteful use of water in its own right.
Seriously folks. What are we going to do about this?
