A Swiss foundation went out and did a fairly in-depth survey of climate change and C02....then came to a non-shocking conclusion. Reforestation across the globe, would fix and resolve all these C02 and climate change issues.
Yes, something that people have been suggesting for two decades....was basically laid out in a science fashion and easily established.
Massive effort? Well....yeah. But here's the thing about this reforestation idea.....no one is against the concept, and the cost factor isn't as bad as one might think. Across the US....you'd probably find at least a million people who are willing to put in six hours per month in some seedling effort.
