Bad blends : biofuel labeling often inaccurate

Thursday, February 28th, 2008

While sampling blended biodiesel fuels purchased from small-scale retailers, researchers at the Woods Hole Oceanographic Institution found that many of the blends do not contain the advertised amount of biofuel.

The Brazilian government was forced to admit that the destruction of the Amazon rainforest has returned to ecocidal levels. An area the size of Belgium, taking thousands of years to evolve, was destroyed in the past year alone. Some 20 per cent of the forest has now been trashed, with a further 40 per cent set to be slashed in my lifetime. This is steadily happening to all the rainforests on earth.
