However, since the Great Barrier Beef (thanks to the bovine being elevated to holy status by the Hindu religion) stock is nowhere near depletion (it's actually burgeoning), it's a shame that cows are now a critical environmental hazard. No one is interested in checking their growth and few are willing to eat them. To make matters worse, the GoI not-very-recently danced to the populist tune to appease the masses and banned slaughter houses for cows in India. So even when they are of absolutely no use to people (like in old age), we can't terminate them. The useless methane production continues unabated.
I'm not advocating non-vegetarianism over vegetarianism in any way. I'm only saying that there could be a positive side-effect to consuming meat, lame though the excuse may be. BTW, while discussing the issue with my friend, I misquoting the proportion of cattle in India. It was way off the mark, though I now stand corrected.
Coming back to my workstation for some intellectual fodder (Yahoo! News), I came across this article that was very relevant to the issue.
