Yeah, it didn't blow my mind but I'm glad that people do the science so we can actually quantify these things. They had big improvements up to 4 species and then the gains were less as they increased it.
Of course this doesn't mean you can drop monoculture in agriculture. You still need your grains to mature at the same time so you can harvest mechanically. Buyers don't want mixes of stuff either. All that jazz. But lawns would probably be much better off with mixed plants.
I didn't say a word about boomers, I was replying to a post about the industrial revolution and 200 years ago.
But to get back to my point, in 1993 the cumulative emissions were 861 billion tons and in 2023 it was 1770 billion tons. So almost perfectly doubled in 30 years.
