One great resource for doing that is the Swedish-based Agricultural Biodiversity Weblog, which I recently added to my blog diet. Many of the stories you’ll find there have been written up elsewhere (often on Worldchanging), but I don’t know of any other news-aggregator-style blog that covers the subject so well. If you’re into this subject, you should be reading it.
Thanks to Alex Steffen at WorldChanging, to which I have long subscribed. Seriously, it’s always nice to be appreciated.
p.s. Alex, You can’t believe everything you read in a domain name.
