Great thread! Maybe this will help more people get ideas on ways to help further.
I have:
-Learned the best ways I can to take care of my pigs as well as my other animals.
-Rescued animals.
-Pursaded others to rescue instead of breeding/buying.
-Stopped supporting petstores.
-Went to petstores to try and convice people to not buy animals from there, and to educate people on the proper care of animals they already have. (Helped a lot of people doing this).
-Become a vegetarian.
-Pursuaded a few people to become vegetarian.
-Helped people online (various boards) take better care of their animals.
-Fostered animals and then rehomed them.
-Donated (and continue to donate) to shelters.
I think that is it for now.

Kudos to everyone!
