I have a hard time understanding why people give this any credence. First off, there have been ruminants on Earth since the beginning of recorded history. Secondly, cattle are one of the best ways to actually put carbon back in the soil. Yes, they can actually sequester carbon. They can do this while making nutritious food from otherwise mainly useless land and maintaining the habitat for wildlife.

If they want to attack someone in agriculture, they should go after the old farts plowing five times a year to grow ethanol and the people in Brazil burning forrests and degrading the soil. Those activities actually release CO2.
