You see: this is exactly my problem. We got busy all the time, and instead of stopping for a moment, we kept on piling problems upon problems until they turned to be predicaments. Resource depletion is a case in point: we kept using more and more of them every year, and now that one of them (oil) starts to show signs of peaking and decline we tell ourselves: no problem let's use another one. But hey, we only have this single planet to live on, why don't stop this madness and start living like we want to stay here for long, and not like children who broke into the cookie jar and ate everything.
