If they ate beef, they wouldn't need so many vultures to eat carcasses in the dump.
OTOH, if they treated the cows' dieseases, instead of pumping them full of pain killers to disguise the symptoms, the cows would live longer AND the vultures wouldn't be getting poisoned.

I doubt the carcasses in the dump are just cattle. A lot of dead animals are present. Where do you think all those street dogs, cats, and other animals end up. All in the dump.
And dead cows are not normally discarded, but used in the leather industry. India has one of the biggest leather industries in the world -- dead cows are put to use. A lot of Muslims and shoe-making castes depend on dead cows' skin.
