On Friday, a Greenpeace team broadcast a live webcast from the heart of the Amazon rainforest, in an area which was still-smouldering after a recent forest fire. Even rainforests have dry seasons and during the current one, fires both natural and man-made are devastating huge areas.
It was an amazing technical achievement but that wasn't the reason they did it - they were there to show how the forest is being cleared for a variety of reasons (in this case, to open up areas for cattle).
