From the Article:
If humanity continues sucking up resources at its current rate, we will need a second planet to meet our material needs by 2030 and the equivalent of 2.8 planets by 2050. That's the conclusion of the World Wildlife Fund's biennial "Living Planet Report"...
My Comment:
Wow, and I didn't think Earth 2.0 did all that well when it was on TV. I'm going to pull this link back out in 20 years and laugh. What idiocy.
