As far as I'm concerned, any lessening of the consumption of animals is great, and I guess Haas has to be commended for -- at the very least -- being honest that she's merely jumping on last month's celebrity bandwagon for the sake of appearances, but it seems to defeat the whole purpose of Freston's book, which makes it seem a little pointless and pathetic.
The UK's Times Online had a decent (albeit short) interview yesterday with one of my favourite vegan environmentalist celebrities, Woody Harrelson. He and his wife founded a group called VoiceYourself and have a great website well worth checking out. They promote veganism, organic living, peak oil awareness and community. They also emphasize the power (and accountability) each and every one of us has as a consumer -- something so many seem to either shrug off or forget when feeling overwhelmed by this global mess we've let snowball.
