True, cows fart every 30 seconds, times millions of cattle. Termites are still number one though, right up there with swamps. Maybe we should eat termites.

"220 times as much CO2 in the Earth's atmosphere as methane", but how did it get there, how fast is it increasing and why?

The increase in CO2 got there from fossil fuel use and changes in land use.

How fast is it changing? See graph below. The Earth was going through cycles of ice ages until the beginning of the industrial age, and then the CO2 levels just took off.

Didn't we go around on that before?
As I recall, cement production is as much a problem as anything.

Back to innovations.Terra preta is the dark rich soil that farmers used to make in the Amazon region before the advent of slash and burn agriculture. Apparently, using charcoal instead of ash builds the soil increasing fertility and sequestering carbon. This addresses the ecological disaster of burning vast areas of rainforest and feeds people. win win
