I doubt that includes insects, bacteria and krill Krill biomass alone is significantly bigger than humanity's. Insect's and bacteria too. This article discusses a study that claims humanity is ~1/10000 of total biomass, including plants. https://www.smithsonianmag.com/smart-news/humans-make-110000th-earths-biomass-180969141/ https://www.smithsonianmag.com/smart-news/humans-make-110000... In general large animals have been already devastated by the last ice age and then changes resulting from that. Even without humans large animals would be significantly less diverse than in many periods before. Of course human's killing spree is not helping either. The xkcd article is probably about large animals, but that's a kind of large animal chauvinism. Why do the small guys not matter? Yes they're in decline too
