I do have an addition to offer to your first sentence. The thing is, people don't care about almost anything that affects others (or even themselves). Most people act or react based on their habits and what's convenient for them. If most people were rational, then things would be a lot better for humans and non-humans.
Since you yourself referred to it as "a holocaust", and seem to know more, you could still make changes, however small they may seem to anyone else (or even to you).
