>a year and growing blazingly fast.

	This trade looks unsatisfactory in several ways, e.g

1.  What fraction of the money collected is absorbed by the 
bureaucracies involved?

2.  What fraction of the trees planted are properly cared for, so as 
to have a good chance of actually incorporating much carbon by 
growing for some decades?

3.  Is it ethical to fertilise the ocean in attempt to stimulate 
carbon fixation by algae?  What are the actual ecological effects of 
this caper?  How much carbon is emitted by the system to deposit the 
nutrients in the ocean?  Is it actually being done, rather than 
presented as an image to "justify" Silverjet® etc's emissions?
