[Terrapreta] More misguided nonsense:

[Larry Williams]

Max-------Just to be blatant in answering your question. Big money  
doesn't make money from bottom up solutions nor does it wish to  
accept a financial emergency. To fuel the fire of impending crisis,  
see: "RBS issues... crash alert". The comments to the article reflect  
a wide variety of opinions for your consideration. We do need to sell  
the concept of Terra Preta (Terra Preta nova) with our current  
understanding of the process, in my opinion, asap. The internet is  
likely the best avenue for us. I doubt that we have have time for  
extended research and that one should do their own home charcoal tests.

During this period I see the need for me to get a good night's slept  
and to meditate over the personal options open to me. Your thoughts  
and the thoughts of the members of this list are very important. Of  
course, there will be some verbiage that will stick to the statue quo  
as important. I am not in that camp. I hope that I am wrong on the  
urgency needed to spread the word. Take care-------Larry
