Eating meat and gas-guzzling

What's worse: gas-guzzling or eating meat?

Recently Heather Mills showed up for a photo shoot to make the connection between global warming and eating meat in a gas-guzzling SUV. While Ms. Mills is right about the meat eating and global warming connection, there is also a big connection between gas-guzzling and global warming.

So does Mrs. Mills have a leg to stand on? Sadly, she does not - no pun intended.

Nonetheless, the point Mills is trying to make is a strong one. Al Gore, for example, talks about how dangerous global warming is, how the world is on the verge of collapse, but he could probably have a bigger effect on global warming by going vegetarian, yet this isn't part of Gore's inconvenient truth. Why?

Maybe the goal to being a good environmentalist is to do less lecturing and more living by example?
