Google Misses Environmental Friendliness By THAT Much...

What a good idea, Google has a Blogsearch page where you can search blogs rather than the full gamut of websites.  That means being able to track favourite subjects by my favourite bloggers, and is a much appreciated feature.   I can also search broadly by categories.  Looking at the list I see


Top Stories

US
World
Business

Video Games

Oh okay, cool, cool...  But now I am wondering.  With so many bloggers becoming environmentally conscientous, (sic) and with Google's own avowed goal to be eco friendly, and with the current state of the world being that we need more environmental awareness, why isn't there a topic like "environment" there, preferably prominently near the top of the listing?

Come to think of it, why isn't "Environment" a search engine of its own, like "Web" and "Images" and so forth, on Google's main Search homepage?  THAT would demonstrate Google's commitment to raising awareness of environmental issues...
