Quoting Chuck Hards <chuck.hards@gmail.com>:
A fire may actually reduce the dust. If there is nothing for cattle to graze, they won't be out there disturbing the crust after admittedly infrequent rains.
Another reason to eat meat! If you think about it, it could help the Earth to cool. With less cows, there will be less methane emissions and with no cows to graze, plants will thrive. An increase in plant growth will result in less CO2 and more 02 which is beneficial to life. With more 02 for people to breath, folks will feel better and more refreshed and will likely be more productive, and we all know what being more productive will do to a society. Yes, lets lay down the bean sprouts and get back to eating beef. Beef, it's what's for dinner... Great idea Chuck! ;)
