Humans: Find new species in the ocean

Also humans: Fishes the species into extinction.

Classy.

Creating it from electricity is highly inefficient, so that’s why it’s made from other fossil fuels (that in theory would have been wasted). If hydrogen was easily compacted and stored long term it would work, but those are the biggest problems it faces, along with having a much lower energy density that fossil fuels. Hard to beat those carbon bonds without going nuclear.

More a potentially infinite (within human lifetimes) heat source from a still-warm Earth interior. Limited in that you can’t harness it from anywhere other than local.

I hadn’t heard of that, but it makes sense that there would be some minimal number, which would certainly be fuzzy and vary depending on environment and species groups. A basic but good example of how more numbers creates stability is the old rabbit and fox simulator. You could get variables that had regular cycles, but it was very easy to spiral out of control. Having more things and interdependence would dampen these changes.

For one, an invasive species could force a lot of other competitors into extinction, dropping the diversity. Then the now dominant invasive species suffers its own decline, leaving much less left.

Since it’s just one screw, I’d find a matching sized bit for the other screws and carefully drill it out. Then replace it with another screw a bit larger. Or just leave it open, cases tend to snap together and the screws are just to make sure it doesn’t pop open.

Then there’s the feeling when you finally let something go that you’ve had for ages just gathering dust, and suddenly a need pops up for it.
