Yep, it was a far better environmental solution back in the 70s, when cattlemen built huge feed lots with 10,000 or more head and kept them all cooped up together and fed them processed feed including cotton hulls, molasses, and whatever grain they could get the cheapest.

Mis-managed use of the environment will continue to be a concern as long as we keep allowing people who know nothing about what it takes to conserve the resource to make decisions about how it will be used. Munching tree limbs is bad, but letting the whole forest burn up because they've outlawed logging and even clearing out the debtritous is causing the greatest loss. There's a whole lot of things we could be doing better to conserve habitat and promote the beneficial use of the wilderness. Greed and the ignorant apathy of the electorate condemn us to continue soiling in our own bed.
