if you are thinking of animals, JBS Haldane had it right: god has an inordinate fondness for beetles.

But in the scheme of things, animals aren’t really that big a deal:

> Of the 550 gigatons of biomass carbon on Earth, animals make up about 2 gigatons, with insects comprising half of that and fish taking up another 0.7 gigatons. Everything else, including mammals, birds, nematodes and mollusks are roughly 0.3 gigatons, with humans weighing in at 0.06 gigatons.
