Please explain how it is efficient to feed anywhere from 5-12 units of calories to an animal, to get out 1 unit of calories. Running plant food through an animal does nothing to increase it's value, and all you're adding to it is a) saturated animal fat, which raises your cholesterol, c) trans fats, and b) cholesterol itself, which yes, does affect your serum cholesterol levels, albeit less so if you already have a high intake of animal products.

And to address your initial comment, human-created wildfires have been on the rise to make room for grazing cattle and soy growth - to feed back to the cattle. A 3 second search will show you that. How else do you think animals are being fed?

Be honest - you want to eat meat because you like it. I understand, meat tastes good, but it doesn't justify this. A whole foods plant based diet is the only diet proven to reverse heart disease and chronic illness, period. Furthermore, it's bad for the planet and is the direct cause of these pandemics that have plaguing humans for ages, but particularly in the past 20 years.
