      Some questions I am interested in 🦁🐼🐝 Why do you care about biodiversity? What does it mean to you? Why do you think it is important?

      It's not mainly biodiversity per se I care about. I wouldn't get excited about a proposal to do something that would cause a lot of new species to evolve. It's the loss of existing species I care about.

      Why do you care about losing existing species? Functional value? Beauty? Something else?

      Partly that the current ecosystem took so long to evolve that there are lots of interdependencies (more than we realize) and thus dangers of cascading effects. Partly that it took so long for most species to arise that it seems a waste to lose them.

          There are often species-unique genes that can help with the design of our own species. Biodiversity means a wider range of these pre-built mechanisms we can study and appropriate. (e.g. why are some jellyfish able to live forever? how does hibernation affect metabolic rate?)

          Should we preserve species if there are very few individuals left? Maybe by introducing more organisms, we could disturb the new equilibrium.
