Biofuels, or at least most forms of them, put wealthy drivers in competition with poor peoples' food. This can't be the answer.

Aside from that, these numbers for displacement, coming as they do from the IPCC, are probably conservative. We are already past peak oil, the fuel that transports our food thousands of miles, past peak grain worldwide, and past worldwide peak fisheries output, despite improved fishing technology.

Our current population is not sustainable. We are treating our renewable resources as non-renewables, essentially mining them. This means that to support our current population, we are stealing from future generations. We're mining our top soil, our fresh water both above and below ground, our forests, etc.

I think it may well turn out that Malthus overestimated the population this planet can support when he said one billion. I'm not sure the planet can sustain more than one percent or so of its current population, if sustainability is defined in thousands of years.

If we don't reduce our population voluntarily, it will be reduced for us.

Dear Canadian Prime Minister Harper,

Please keep Canada's Kyoto Protocol commitments to reduce greenhouse gas emissions.

I hope you now recognize that global warming threatens to be a global crisis - from melting Arctic sea ice, to burning and insect damaged forests, to droughts and floods displacing and killing millions of people around the world. Canada must do its fair share to prevent catastrophic climate change.

Respect Canada’s Kyoto commitments and pass Bill C-30 now!

Sincerely,

Paul Malouf
