"The group's biannual Living Planet Report said the natural world was being degraded "at a rate unprecedented in human history".   It warned that if demand continued at the current rate, two planets would be needed to meet global demand by 2050."

"They added that if the world's population shared the UK's lifestyle, three planets would be needed to support their needs."

 

From ABC, Humans living far beyond planet's means: WWF

"If everyone around the world lived as those in America, we would need five planets to support us."

"People are turning resources into waste faster than nature can turn waste back into resources."

 

That last quote is the big one.  Like everything else, the Earth has to be able to replenish itself.  We are not allowing it time to do so.  We, especially Americans, want everything now, now, now!  It's all about "me, me, me!"  But we cannot sustain this kind of living.  Everything in America is defined by materialism: success, happiness, and even life itself.  We have to adopt a new outlook on life in general.  We need to conserve and care about the environment....you know, the thing that allows you to exist.  I know that some people won't care about this revelation or even think that there is a problem.  But that is because they are STUPID.  We have all got to understand that we are part of the Earth's ecosystem, and that the ecosystem has a balance that has to be maintained for our own survival.  We are not respecting that balance.
