[p2p-research] Scientific American on the coming Malthusian Crisis

[Michel Bauwens]

yes, more oil-based poisons in the soil will do the trick <g>

more markets ...

as if it was not the marketization of food which led to the crisis in the
first place, along with the speculation of food prices and the planned
destruction of any reserves of regulation ...

will they never learn ...

reminds me of the plans to destroy free range chickens in thailand because
'of course' they are dangerous for the bird flu ..
