In just over seven months, humanity has used up a full year's allotment of natural resources such as water, food and clean air – the quickest rate yet. The point of "overshoot"

Aren't water, food and clean air all renewable resources?

Don't know how water works, but there must be some way it gets renewed, I dunno maybe when urine evaporates it takes all the pissy bits out and turns it back into water to rain down again or something? Food is easy. More animals are born and more plants grow. Clean air is even easier, just needs more plants to consume the carbon dioxide in the air and release oxygen, the opposite to what we do, and since more plants is part of the food one anyway...

They are. The problem is, though, that we are using renewable resources quicker than the Earth can replenish them. The overshoot day is when we've used more resources than the Earth will have replenished by the end of the year.
