Submission + - The Future of Sustainable Farming Might Be Bugs (

gthuang88 writes: The idea of insects as a protein source to feed the world isn’t new. But the U.S. agtech industry may be warming up to it. Now a Seattle startup called Beta Hatch is growing and harvesting mealworms and their waste, about 600 pounds a week, and packaging them as chicken feed and fertilizer. The goal is to be healthier and more eco-friendly than traditional feed, which uses soy. Together with companies like Tiny Farms, Exo, and Six Foods, this represents a new wave of efforts to commercialize insects for sustainable food and farming.

Not sure where you got this 100 year figure, but I'd think critically about that if I were you. CO2 is a very stable molecule. Plants are not good at sequestering CO2 since they die, rot, and emit CO2 and other greenhouse gasses (unless biochar or another carbonization method is employed). The biosphere exchanges carbon with the atmosphere, but the amount in circulation doesn't change quickly. Formation of CaCO3, Oil, coal, and some other carbon-containing inorganic materials subtracts from the carbon being exchanged between atmosphere and biomass , but these are accumulated in the crust by geological process involving plate tectonics, so they are extremely slow. I think conservatively (and a quick google search confirms) that it will take 1000's of years (perhaps 10's or 100's of thousands) of years for CO2 to return to a level closer to where we started before the industrial revolution unless we intervene somehow. Assuming we eventually quit *adding* to the CO2 in the atmosphere.

Effectively, assuming new creation, effect is 100 years, NO2 is 10-20, methane circa 10.
