You probably make charitable contributions every now and then. If you don’t, well, it’s something to think about. And especially now that GlobalGiving, the well-respected online donor site, has set up GlobalGiving Green, a collection of 25 charitable causes that are addressing climate change and sustainability. You can read more about the new initiative here in the New York Times, or cut to the chase, head straight for GlobalGiving Green and do some giving of your own. Gotta love their tagline: A New Shade of Generosity.
