Death by CAP
How EU economists are ‘killing Europeans through CHD’ Surprisingly, it’s not the acronyms that are at the root of the World Health Organization’s damning accusation, it’s our old friends, saturated fats. The common agricultural policy (CAP) was put in place by the powers that be in Europe, not just to confuse any non-economist who has…

Algae for biofuels: solving the land-use problem
It’s becoming increasingly obvious that there isn’t enough suitable land space to grow crops for food and feed as well as for biofuel, and to retain the forests and other land uses that sequester carbon in huge quantities. As the Nature blog ‘The Great Beyond’ points out, two articles published in Science in February argue…
Coping with extinction: can plants cope with the loss of their dispersers?

Assigning cause and effect in…
Virgin flight fuels aviation and energy debates
The first flight by a commercial airline to be powered partly by biofuel has taken place. No passengers were on board, and just one of the aircraft’s four engines ran on fuel comprising a 20% biofuel mix together with 80% normal aviation fuel. But with both aviation and biofuels arousing strong emotions among environmentalists, the…
