Plant agriculture is especially rice paddies, I guess.
- graeme 6y agoIf methane is only 3x larger than before, that suggests animal husbandry is only a small part of the increase. The first two categories are almost entirely new. Especially given human population is way bigger than it was in past ages, so past landfills likely weren’t so large. This is surprising to me as I has figured ruminants caused more of an increase. If we could cut their emissions by 80% with seaweed this analysis suggests their overall contribution would be lower than it historically was.
