The impacts of biodiversity loss is not a well-researched topic in EA. A small group of us have begun doing some research into the impacts of biodiversity loss (including mass extinction and its connection to ecosystem collapse) as a potential cause area that deserves more attention and resources.
After preliminary research we found very little active research within the EA community about this topic and only minor explorations from core EA organizations. If you know of substantial, recent research on this topic we would love to read it.
As a quick way to help our community by contributing to an under-explored topic, we invite you to fill out this 3 minute survey or respond in the comments to the question:
What is the strongest argument you know of for & against biodiversity loss as a cause area?
We also want to acknowledge that we have seen substantial research into climate change. We believe biodiversity loss warrants its own targeted research as a separate but related trigger for compounding devastating risk for life on Earth.
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)
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 tha... (read more)
