I think that’s reasonable that biodiversity loss is unlikely to be an existential risk. However, existential risks could significantly impact biodiversity. Abrupt sunlight reduction scenarios such as nuclear winter could cause extinction of species in the wild, which could potentially be mitigated by keeping the species alive in zoos if there were sufficient food. These catastrophes plus other catastrophes such as those that disrupt infrastructure like extreme pandemic causing people to be too fearful to show up to work in critical industries, could cause desperate people hunting species to extinction. But I think the biggest threat is AGI, which could wipe out all biodiversity. Then again, if AGI goes well, it may be able to resurrect extinct species. So it could be that the most cost-effective way of preserving biodiversity is working on AGI safety.
