Today is the day that our petrol has to contain 2.5% biofuels. It is also the day when at least 33 countries are facing the prospect of serious social unrest because of rising food prices. The biofuels - food equation looks like this. One tank’s worth (25 gallons) of ethanol requires land that might otherwise feed a person for a whole year. Wholesale turning over of land to biofuels has already made an impact on the world food situation.

What seemed like a worthy government initiative at first glance now looks horribly naive and points to a central flaw in our thinking. The inconvenient truth is that we will not be able to replace the cheap oil that we have consumed with such profligacy for the last 50 years or more. There is no quick techno fix to the issues of peak oil and climate change and transport may be the key area where these things begin to bite. We are going to need to change our lifestyles.

And that is where Chooseday comes in.
