The most important result is that plants are the overwhelming winner in the “who weighs the most” contest, coming in at 450 gigatons. Microbes (which include bacteria, archaea, and most protists) come in next at around 81 gigatons. Animals (which includes insects, by the way), barely matter, weighing in at a mere 2 gigatons. It’s also worth noting that these plants are mostly on land. That means that the continents beat the oceans in terms of biospheric mass.
Ah, yeah, I've heard similar numbers before, so while it's still always a bit of a surprise when I see another such number, I kind of expect to be surprised. 🙃
Another set of numbers from a presentation I watched earlier is that in 2023, Germany (with our ~80 million citizens) slaughtered:
47.9 million pigs, cows, sheep, goats and horses.
702.2 million chicken, turkeys and ducks.
I don't know, how much of that is being exported, but it still feels like we're eating our own weight in meat every year, which probably fits in with that biomass number.
