Double Standard

After reading "Hooked on a Myth" by Victoria Braithwaite it opened my eyes to  a lot of things wrong with how we treat and think about other living creatures. I feel that there is this double standard held by humans that we are the only ones who feel and understand. This double standard is also held with animals as well for example how we treat dogs vs how we treat fish. Although this may possibly be true in some areas it's wrong to assume things without scientific proof. This double standard is also held with animals as well for example how we treat dogs vs how we treat fish. People seem to think that if we don't see it it isn't happening. Like how Braithewaite talked about the fish having the same pain receptors as humans. But not only with what Braithwaite mentioned, the way we have industrialized the food industry has made the killing of animals for food so unethical. I'm not saying everyone should become a vegan. I'm trying to say that every living thing deserves to live and die in an ethical and dignified way. I understand our demand is so high for these foods, but there needs to be a better way. I plan on starting to eat only free range meat and looking more into this subject.
