I just spent half an hour trying to give $100 to biorisk mitigation specifically, but couldn't find a good place.
- OpenPhil lists a bunch of grantees in this area, but it doesn't look like a private person like me can donate to them: https://www.openphilanthropy.org/grants/?focus-area=biosecurity-pandemic-preparedness
- https://securebio.org/, where I donated last year, appears to not be taking donations anymore.
- On EA Funds etc. there are only general x-risk funds, nothing specific to biorisk. I don't want to put more money in AI safety since I already do that in other ways.
As someone who runs an organization that does a lot of biorisk work, it's incredibly expensive in staff time and logistics to receive small donations - but if you're giving more than, say, $5,000, you could just email the organizations to ask, and I'm sure they could figure it out.
But as I answered, CHS does have a donation page. (And NTI does allow donations, with a box to indicate where you'd like the money to go, but it's unclear to me if that actually lets you direct it only to bio.)
I see. Thanks for explaining!
