For a long time now, humans have been using up natural resources much faster than they can be replenished. The reason we can still breath and have food available to us is because the Earth started with a vast reserve of natural resources before humans began taking more than can be replaced by natural processes. We are reducing that reserve at a faster and faster pace and one day it will not be there anymore. Frankly this will be cataclysmic for our species.
The Global Footprint Network does a detailed and laudable job of quantifying and measuring it.
