The article has merit in that we are the most efficient in finishing cattle.  We can capture the benefit of added value.  Central and South America are more suited to grass fed cattle but even there they are not as efficient as many are led to believe.  I can take two years to make a yearling due to weight gain and seasonal weight loss.

Brad makes an excellent point overlooked by most who criticize trade agreements.  First, history is on the side of the benefits of trade versus the economic cost of protectionism.  He touched on the much larger issue that is the economic and trading blocks that are developing.  Europe, Asia and the America's plus Canada will shape and form new economic powers.  Inter-regional trade is essential in this new economic landscape.  Thanks for the question and have a great day.
