8. Discourage friends from purchasing forms of entertainment that harm animals.
2014 has certainly shed considerable light on the myriad of ethical issues surrounding companies that keep animals in captivity or use them for entertainment purposes.

9. Write one letter on behalf of animals.
Make your voice heard! Write a letter to local lawmakers when you have a passionate viewpoint on wildlife-related legislation in your city or state. The ASPCA offers a guide for writing effective advocacy letters, as well as a search tool for finding your legislator's contact information.
