It doesn't seem like their point was to trigger? Unless you're triggered by the word flesh?

I'm not a vegan/vegetarian. But I recognize from a purely thermodynamics perspective that meat is less efficient than a plant based diet. They're efficiency losses for feeding plants to another organism instead of just eating those plants directly.

Before agriculture, meat was basically required for humans. Let wild animals consume inedible plants and then hunt using very little of your own resources. Now that equation has been inverted since we control the entire chain of resources.

You can be mindful of environmental issues and efficiency without taking a moral stance on meat eating. There's really no easy answer, it's very complex. Pollution, water use, land use, pesticides, nutrition, etc are all factors.
