why vegetarians eating our rainforests?

You have any basis for this question?
Hamburger-producing cattle are destroying our "lungs," the rainforests. So, every time you eat a burger, you are destroying more of our planet.
If we all became vegetarians overnight, there would be such an abundance of food, that there would be no hungry people anywhere. Our planet, our bodies would be cleaner, and live longer.
We wouldn't have the waste and pollution you have from a meat-centered culture.
We could feed ourselves and a big part of the rest of the world. It would even help the obesity problem, worldwide.

Win, win, win.

The meat that comes from cattle ranching in what was once rainforest doesn't go anywhere near the US or Europe, because of it's inferior quality. Unlike some people have wrongly suggested, it never makes its way to our plates, but stayed in south America. Therefore, us meat eaters in Europe and the USA aren't contributing to the rainforest destruction, even by association.

On the other hand, the soy grown in the rainforest is eaten by veggies in Europe and the US, so they are contributing, albeit only by association (but they like to call us guilty by association when we eat meat, so screw them).

Technically, many chickens are fed upon soy, but that's not as big a problem as the veggies.
