That's not what the dharmic religions say. They don't explicitly say "don't eat meat" because that position is only held to the people on top castes. What they do say is that one needs to lower their foot print as a means to lowering the suffering in the world. A Buddhist monk could eat meat but then he'd be contributing to suffering but it doesn't explicitly forbid it. The Buddha died from eating pork and he's the person one should strive into becoming. Also it does explicitly forbid the eating of pork in the Catholic Bible. Shit they forbid you eating pork on Fridays because of some bullshit made up thing that isn't on the Bible.
