Brazilian meat is grass fed. Which countries more export grass fed meat?

I don't know about countries exporting grass fed meat, but in the US there is a growing movement for raising grass-fed cattle and pastured chickens (for meat and eggs) usually within 100 miles of major cities, as opposed to grain-fed livestock raised in large factory farms.

The Omega 3 to 6 ratios of the resulting meat (and eggs) is better than the grain-fed ones. It seems that a lot of these inflammation problems are not only caused by the diet of the average person but also caused by the diet of the average livestock that we're consuming.

They cut down the rainforest to create those pastures which the cows graze on.

New Zealand exclusively produces grass-fed beef.
