I agree. It's a very intuitive way to introduce people to EA with something they probably already agree with.
Thank you very much. Unfortunately the source I'm using (Our World in Data) doesn't report YLLs. Sources that report YLLs are so sparse that I couldn't have used them for an overview. I'm also not sure whether the results I'm drawing here are in any way conclusive or whether DALYs are such a bad metric of suffering that I'm just reading tea leaves.
I understood the numbers to only contain farm fish and no wild fish. Thanks for the fact about elephants, I didn't know that. A better metric might then be the number of neurons in the cortex. But it would still contain a lot of uncertainty about which regions of the brain are actually causally responsible for suffering and so on.
