Earlier quoted context omitted.
For some definition of ethical, maybe. I guess fundamentally my question to you is, why do you think that human life is worth more than animal life, because that is the foundation of our differences.
tjic didn't say that human life is worth more than animal life. Are you projecting? All life is precious, but we are all still animals. We need food to survive. Almost all life consumes other life for survival. There is nothing more natural than eating.
The idea that eating meat is natural is one of the four main reasons people give (the 4n's: natural, nice, normal, necessary).
A few counters: It is also natural for animals to kill their own. We as humans have decided to rise above this "natural" existence. It is natural for animals to eat other animals. A balanced predator prey system is a healthy ecosystem. This is not what we humans are doing. We are raising a handful of species simply because meat tastes good. Sure there are some cases where humans must still hunt for survival and I take no issue there. But most of us have the resources to eat a plant based diet. Which is healthier for us and the environment.
