New Scientist environment correspondent, Fred Pearce, is currently touring the world and investigating his own footprint, but from a global perspective. He is taking every day items (such as his cheap supermarket jeans, his wedding ring, his morning fairtrade coffee, etc) and travelling to the countries in which they were produced to understand the impact these items are having there. Pretty scary stuff.
During his to Tanzania to visit the fairtrade coffee farmers - “So you buy our coffee for $1.46, and sell it for $12. Is that fair trade?” Hmmm.
