To give just one example, I think Effective Altruists focus far too little on meta-science. Much of what they want to do depends on meta-science, and in science it's quite difficult to fund that sort of work, so it seems odd to me that it's not considered a top priority on 80,000 Hours.
I'm sure there are other areas, but I haven't put an effort into listing them. Global priorities work is pretty hard.
- Buying rainforest land and paying locals to guard it.
- Greening energy production in developing countries. Their electrical grids are already unstable, so even improving energy just when the sun is shining could help.
- Research into oceanic biologic collapse.
- Finding and destroying illegal fishing operations. (Heck, make an AI boat do it, and you'll drum up even more support for AI alignment).
