Others don't eat meat because of the environmental ramifications. By 2025, the world population is expected to surpass 8 billion. It is common knowledge now to know that livestock agriculture is the single greatest cause of world-wide deforestation. The United States is losing its topsoil and overgrazing is the largest cause of human-made deserts. The bulk of corn and wheat grown is for livestock, while more than 500 million peopl e are starving.
Food going to livestock can go directly to the mouths of the hungry.
There are many arguments for eating meat, most of them old and tired ones. The Bible claims dominion over all other living creatures. Well, I don't believe pummeling a baby seal with a baseball bat or gutting a cat in a voodoo rite is exactly what God ha d in mind. Killing to survive or that it's human nature to be carnivorous is a weak argument because very few people are running around in the jungle or woods on a quest for fire. And vegetarians have proven over very long periods of time they don't need to kill animals to survive.
