In regards to eating meat

[Monica]

The petroleum issue is a biggie. But, a huge amount goes into the farming of feed for the cows.

...

The animal farming issue would make a huge dent in the petroleum industry. A side effect would be a surplus of land for actual firsthand food rather than secondhand(getting nutrients by eating something that ate those nutrients)

It does not take much land or effort to grow food that goes straight to the mouth. It takes a lot more land and effort to grow enough food for the animals in order to eat them. Why so much effort?

The meat industry is so grossly inefficient and harmful to the environment that it's pointless to talk about sustainability...there's just no comparison.
