Something of a debate has developed on the venerable Today programme about light bulbs. It kicked off when Tesco boss Sir Terry Leahy appeared yesterday plugging a £25 million investment in a sustainable consumption institute.

So far in our light bulb campaign, we've bashed companies like Woolworths for not being proactive enough in sweeping inefficient incandescent bulbs from their shelves, but we're also working on more positive angles to demonstrate the plus-points of energy saving light bulbs or compact fluorescent lamps (CFLs). One of the frequent excuses used for not switching to CFLs is that they're unattractive/ungainly/ugly/inconvenient (delete as applicable), but that's not so. They now come in an exhaustive variety of shapes, sizes and colours and can be just as aesthetically pleasing as old-fashioned bulbs.

Jason Bruges certainly thinks so. One of the UK's top interactive installation designers, he’s currently working with us on a new work to demonstrate the versatility of CFLs. He's no stranger to low-carbon design projects - his recent installation at the South Bank in London, Wind to Light, featured mini-wind turbines powering hundreds of LEDs, and his studio's latest work will be the front of house feature at this year's 100% Design at Earls Court Exhibition Centre later this month.

As the narrator of this startling video states, "working in the Amazon forest is not for the faint of heart." In the past, people from campaigning organisations have been bullied by land owners and workers, facing intimidation, violence, death threats and even murder.

There have been further developments in the Amazon. As we reported last week, Greenpeace Brazil published its investigation into deals between a Brazilian government agency and logging companies over areas of rainforest under the guise of a land settlement programme.
