Humans are part of nature too, and we have our animal instincts same as any other animal. Only thing that differs is our capacity to self-reflect and exercise agency over our place in the ecosystem. What matters is that we have respect for life and don't take it for granted. I agree that factory farms, hunting for sport or luxury goods like furs, etc. is wrong, but I don't see a problem with a small farm raising some animals as long as they're treated with respect and given a comfortable life. All animals - including us - are dependent on others for survival.
