Afraid I have a sightly warped viewpoint on this subject, Animals are living creatures, they feel pain, but we have to eat to live, and we are naturally carnivores.
We eat plants, they are living creatures, but we don't know for sure that they feel pain. Plants do everything we do, just on a different timescale, (bears thinking about).
When you eat your Banana, its still living, Lettuce is still alive when you eat it, as is most fruit and vegatables, you boil some vegatables, when you put them in the pan of boiling water, they are still alive, we just don't know if they are hurting.
Yo live, you have to put aside your concience
