Green - An environmentalist community

I don't totally disagree with you. Many animals from bugs to mice and birds are killed in the process of farming and the delivery of those goods to market.

If I hunt a deer, I can tell you exactly what my environmental cost was, exactly one deer. It's not something I'm proud of, it's just getting food for my home. I'm very grateful to it, and appropriate the sacrifice I asked of it.

You don't have to agree with me on that. If you don't use any animal products, I appreciate your decision. But no supply chain is free of environmental cost, and I think it's fair to ask you to keep that in mind too.

Because humans are powerful enough that we are a bit like gods, and we have to make these choices between which lives we keep and which lives we kill.

Is it ethical to allow the hunting of African game if that money funds the conservation of many more animals? We have to make that trade off. Ethics are subjective, and I'm firmly on the side of allowing hunting as are many other people.

In New Zealand, as with other isolated islands, there's a unique population of indigenous birds that are now being massacred by introduced mammals. Is it ethical to hunt and trap and poison the introduced pests to save the indigenous birds. We have to make that choice.

A runaway trolley is going to kill 5 humans unless you switch it to another track where it will only kill 1 human. Is that ethical?

A politician could choose to lower the speed limit of a road to 10 km/h, saving lives but costing the economy, quality of life, and future election wins. Is that ethical?

Ethics are subjective, but we have to choose.

I see only humans as sentient so no question of ethics there. Though sentience by itself isn't sufficient unless you have a very shallow sense of ethics. For example self-defense can involve taking a being's life against it's will. But that in no way suggests the action was unethical.
