You should not forget Ben Goldacre's chapter about Matthias Rath's campaign to cure AIDS in South Africa using vitamins.

After the ice is gone, would Earth proceed to the Venus syndrome, a runaway greenhouse effect that would destroy all life on the planet, perhaps permanently? While it is difficult to say based on present information, I've come to conclude that if we burn all reserves of gas, coal and oil, there is a substantial chance that we will initiate the runaway greenhouse. If we burn the tar sands and tar shale I believe the Venus syndrome is a dead certainty.
The surface temperature on Venus reaches 460 deg C. Seems extreme but I have no doubt that James Lovelock would agree James Hansen.

The chemistry of the ocean is changing at an unprecedented rate and magnitude due to anthropogenic carbon dioxide emissions; the rate of change exceeds any known to have occurred for at least the past hundreds of thousands of years. Unless anthropogenic CO2 emissions are substantially curbed, or atmospheric CO2 is controlled by some other means, the average pH of the ocean will continue to fall. Ocean acidification has demonstrated impacts on many marine organisms. While the ultimate consequences are still unknown, there is a risk of ecosystem changes that threaten coral reefs, fisheries, protected species, and other natural resources of value to society.

In Session 5 Prof Caroline Saunders from Lincoln explains why she thinks NZ should not try to "feed the world." You can download it and see what she had to say if you are interested.
Chris Laidlaw interviewed Associate Prof Hugh Campbell from Otago Uni prior to the conference and Campbell said that "NZ cannot sustain a first world lifestyle by selling agricultural exports to people in Haiti". His view was that local farmers in third world countries needed to be supplied with the technology to improve their farming productivity. He went on to say that NZ agricultural exports to the third world tended to be aimed at the growing middle classes and gave the example of a joint venture between Nestle and Fonterra to market ice cream in Mexico.
