As do many people, I frequently use Google  as a research resource.  Sometimes I forget the power of the tools that have become a routine part of life.  I just noticed this after doing a search:

About 33,200,000 results (0.50 seconds) 

Over 32 million results in 1/2 a second.  I used to think that grass or insects were the dominate life form but I am no longer sure.
