I see biodiversity / ecosystem loss as the original environmental concern. Climate change has surpassed this area in importance, and there are legitimate grounds for this. Climate change has the potential to be a major cause of ecosystems/ biodiversity loss. One issue with this perspective is that the less biodiversity we have, the harder it will be for ecosystems to adapt to climate change. (BAppSc: Enviro Management)
I definitely agree that climate change has surpassed biodiversity loss.
I have doubts that biodiversity loss is dangerous or liable to cascade, but I very much want to know the likelihood and size of expected harm. I want to know how plausible and how large negative regime shifts can be. I am also concerned about the longtermist aspect of losing irreplaceable species.
*I should note that these are my personal views, and don’t represent the other people also interested in biodiversity as a cause area.
It really depends on the level of danger/cascade we mean here, because several ecosystems already have shifted into states that no longer provide resources which people depended on for their livelihoods.
Here are my reasons for x-risk skepticism: Life rapidly takes advantage of open opportunities and is built to do that. Evolution takes place on long timescales and (I think) has some selected-for resilience for 99.9th worst case scenarios. The earth has had 96% of life wiped out and still had large animals make it out. I can’t think of an ecosystem that took down adjacent ecosystems with it. I also can’t think of cases where an area was transformed into a totally lifeless ecosystem (except chemical spills). To the contrary, I see decimation and “recovery” into ecosystems adapted to decimation. My current model is that ecosystems degrade gradually and its a very very low point when individual species are necessary for survival and sudden collapse is a potential threat. I think we are far from that being the norm.
This is all concerning worst-case bottoming out or cascadelike patterns. I think there is a lot of space in-between here and oblivion worth addressing. And on the positive end, biodiversity and ecosystems seem to give high return value and stability vital for civilization and flourishing. Hence I still think biodiversity has lots of value, both now and in the future without it being a source of dire xrisk.

Why not? Out of interest?
