You're right of course and its something we've all known for a long time now. Its just that people really don't care. Post a thread about doing to a dog what we do to billions of animals every year and posters will call for the head of the abuser. Then they'll sit down to a meat-centered meal and pretend they're not responsible.
They also don't care about the incredible waste of natural resources that comes with the meat industry. Take a 90 minute shower. That's the water it takes to produce one hamburger patty.
We're seeing water shortages across the country now and its going to get a lot worse.
If you care about your own body, cruelty to animals and leaving the planet to the next generation, don't eat meat.
If you're interested in educating yourself, read John Robbins (son and nephew of Baskin-Robbins), Kathy Freston.
Read The China Study. About the horrors of dairy products, read Whitewash.
If you don't want to cut out all meat, cut back. Treat it as a condiment. Its better for you, better for the planet and a lot better for the animals.
