I've heard some reports about science intending to capture (that should be some trick!) bovine flatulance to use as fuel. Statements are made about how, collectively, it causes damage to the atmosphere. (If such a scientific advance were possible, too bad somebody hadn't thought of it back when my eighth grade classroom was in full fury.) But I digress.
Can you imagine the titanic amount of gas the dinosaurs produced? Why hasn't that been ever mentioned as a factor in the biological - zoological and botanical - and atmospheric evolutions on Earth? Huh? Huh?

At the very least, wouldn't it have been good for plant growth and development?
