Kind of weird giving request here:
I'm looking to internalize my most impactful negative externalities (primarily by giving to effective charities). The clearest negative externality I have is my carbon footprint, so I'm offsetting my carbon by donating (~$15/year to CfRN).
What are the other high impact negative externalities I have, and how can I donate to offset them?
(For context, the macro idea here is to experiment with how individuals can have, at the worst, a "net neutral" impact on the world.)
