I'm always amazed when this argument is raised. I can't fathom anyone actually believes more life, for the sake of life, is "better". It strikes me as a bad faith argument. There is a colossal difference between ending a life and preventing one from happening.

About 21.8% of the world's population is vegetarian [1]. Let me flip your question: Do you think if those billions of people began consuming meat, the world would be the same? Of course not. Assuming meat production could rise to fit this 21.8% increase in demand (it likely couldn't), the planet would be much worse off. So, yes. Although an individual's choice to not eat meat doesn't do much, in aggregate, it's massively important. "The inactive must justify their sloth by picking nits with those making an attempt"
