Seconded! I've tried goat's milk before, and it just tasted... weird. Probably because I grew up with cow's milk, but, still.
Have you heard of goat milk? lol xD
This is not entirely correct.
Actually the way to get cows to decrease C02 emissions is to feed them what they naturally eat, in an environmentally sound manner. Rotating herds of ruminants (grazers) through fields actually sequesters more C02 than the cows produce, which means that cows raised this way are carbon negative.
