you’re currently killing 0.6 animals per year. If you donate six cents per year to animal-related charities, you’re animal-neutral.

Uh, that's not how ethics works. Unless you're a strict Utilitarian. Which I'm not, and find absurd.

Save the Children claims to save a child's life for $1/day. By his logic, if we assume the average child is 10, a serial killer should be pardoned so long as he donates $3650/human killed.
