Your animals are pets, not a food production system. Those animal farming practices will not scale to feed 8 billion people. Most ~humans are not receiving the standard of care you claim to be providing your animals with.
The idea that continuing to live is a personal decision is tempting as a part of a moral code (Ayn Rand takes this idea to absurd conclusions, for example.), but depression/suffering must be ~extremely severe for people to get over their self-preservation instinct. You are ~not, in any meaningful way, making a conscious decision to continue living for the rest of your natural life. You never gave consent to be in the situation you're in as a human being, and the animals you're raising ~certainly didn't.
