I've always been interested in the social, environmental, and economic consequences of the decisions we make.
Where we live, what we eat, where we shop, what we buy, how we travel ... the list is endless. I stumbled upon a blog which explores those sorts of decisions in a great deal of detail. It's called Walletmouth, and the slogan at the head of the blog states: "Your wallet is a mouth. When you spend money you tell the world how you want it to be".
I've only begun exploring the blog, but it has an amazing array of resources on corporate behavior, which seems to be the blog's main focus.
The blog also covers more mundane consumer environmental issues. The most recent post (as of this writing) is an article on diapers, with a description of a sort of hybrid between disposable and cloth (reusable cloth outer layer with a biodegradable disposable liner. Not as much discarded as a disposable, not as much transportation energy consumption as a diaper service).
Overall Walletmouth is interesting, entertaining and informative. The blog's name and slogan is great, too.
