Life consumes other life to live. Humans have evolved to eat meat, we are living beings, a part of this planet just like a lion or hawk.
The lives we must take to live, whether they are plant, animal, or both, were not decided by us but by nature. Killing and eating to live is the only moral reason one has to harm another living being. This is not nice, it’s just nature. Does the wild boar chased to it’s death by a tiger not suffer a cruel death? Does that make the tiger evil?
Animal Agriculture and Massive Human Populations
Our modern animal agriculture industry is what’s wrong, it is disgusting and evil and treats conscious beings as objects indifferent to their suffering. But feeding 8 billion people can only be accomplished using an industrial food industry.
The answer is not trying to turn 8 billion people into vegans, that is simply not going to happen. Rather, we should be striving to reduce our numbers and change culture to respect animals and their sacrifice for our food.
One of the more effective ways to do that are to eat like a “flexitarian” and reduce the amount of dependence on the animal agriculture industry. The other key way to reduce animal suffering is not something an individual has control over – to have a human population that is not grotesquely oversized for the environment.
Our species has no entitlement to grow to maximum size and kill other beings to support this unnecessary growth. The Haber-Bosch process effectively caused human eutrophication, an imbalance, and like the overgrown algae causing fish kills in lakes, our numbers are causing the unnecessary death of a great many species in our environment and will lead to ecological failure if not taken care of. The solution to eutrophication in a lake is stop the overflow of nutrients.
While it’s possible in modern times for a person to live on a vegan diet, it’s not a normal, not healthy without significant effort and education, or more moral.
There will never be a time when no humans eat meat. Therefore, we should strive to reduce the suffering required to sustain our own life. Eating flexitarian is a highly practical way to do this. If an individual is willing to sacrifice their health and/or work to gain the knowledge required to be healthy without consuming animals at all (i.e. be vegan) then good for them, but this cannot be expected to occur globally.
