Green Gamma is a search engine and directory for green services, products and information. You can add your green site to the directory (click on "Add a Listing") and if approved it will automatically be listed in the greengamma search engine as well. We would appreciate it if you would post our reciprocal link on your web site. Gamma waves are involved in higher mental activity. Green thinking is perceptive and involves a higher mental activity. There you have the genesis of Green Gamma. So if you are in Gamma mode, then you are not thinking of self, but rather are conscious of the world around you. That's a good thing! Whether your site concerns solar power, eco-living or is an environmental blog, or promotes green living in any way this directory is for you! We want to be the hub for people that care about the environment. If you have any suggestions on improving this site or would like to suggest a new category please send us an email at info@greengamma.com
