[All] Part II GRCA watershed forum

Mon Sep 21 11:27:30 EDT 2009

Good points Susan & Jeff,

But here is a new (unknown) source of methane from cities as written  
up in a New Scientist article: Mystery methane belched out by megacities
http://www.newscientist.com/article/dn17479-mystery-methane-belched-out-by-megacities.html 
. Could the world economic recession be forcing more people to eat  
beans?
Is there an opportunity here for the invention of methane capturing  
devices for both cows
(double capture version) and humans? (Personally, I don't eat beans,  
but I do have a
f*rting frequency which will probably increase as I eat a higher  
proportion of vegetables --
and there is no way I will accept being vaccinated.)

With a slight element of seriousness,

Robert
