If you push the argument of OP further you have:
> According to the Carbon Fund you can offset your CO2 emissions for $10 per metric ton. US citizen produce an average of 16 ton per year. So you can solve global warming by just 160$ per year per head, it's really not a big deal.
For me this 10$ per CO2 ton is extremely misleading. It maybe correct for now, but as soon as more people try to offset their CO2, the price will skyrock, because there isn't many 10$ per ton opportunity for CO2 offsetting.
