Gdetrailer,
Too much atmospheric carbon may result in run away global climate change. I believe things are far worse than the least optimistic models.
This is similar to the radiation exposure limits in the 1960ties. The most conservative estimates for safe exposure, ended up being more than 1000 times too high.
How much land does it take to support and feed one person? The best guess is between 5 and 10 acres. But say "goodbye" to meat.
We are losing arable land at the rate of over 100,000 km² (38,610 square miles) per year.
We need to do better.
