I recently watched the documentary Blackfish and I highly recommend it. I love animals. I love animal videos, photos, art and of course, seeing their beauty in person. However, I do not believe we should capture them for that purpose. Dolphins, orcas, and other marine animals do not belong in tanks just as tigers, bears, and elephants do not belong in cages.
The best thing we can do in this world is leave it with more beauty, more love and more compassion. Refusing to support the industries that make animals into entertainment and profit is one small way to ensure that.
