GM crops do not increase yield
A lecture given by Ann Clark which shows that there are NO yield increases associated with the GM traits introduced into GM crops -- yield increases, where they occur, are down to conventionally bred characteristics which are deliberately incorporated into the same "GM packages." The non-GM isolines (which would boost yield anyway) are then deliberately not released onto the market -- which is something Monsanto and the other GM corporations can decide on quite cynically because they control the seed trade.
This point is deliberately ignored and misrepresented by the biotech industry. The spokesmen still pretend that they insert "yield enhancing" genes, which they patently do not.
