It's been a while, so I'll just briefly start with G8

"The G8 countries represent just 15 percent of the world's population but they produce 45 percent of all human emissions of carbon dioxide, the leading greenhouse gas," said Ethan Green of Rising Tide North America, a group supporting the protests in the US.

Protesters who went to St Petersburg for the G8 meeting on energy have been in trouble. They blockaded a main road used by G8 participants in Russia's second city and 37 were subsequently arrested by riot police. Some had to be forcibly removed when they refused to co-operate and remained sitting. Several have complained of abusive treatment and there are reports that they are being denied legal representation. The protests took place in both Russian and English and the protesters were from a variety of countries (I hope they travelled ethically!) and were about G8 states' stance on nuclear energy. The activists maintain that the money to be spent on nuclear energy would be better invested in development of long-term renewable sources. They warn of the dangers of nuclear power and the time required to build new reactors among other things. Similar protests were held throughout the world in many major cities. Here's what seems a resaonable summary of the story. Here's the official G8 website and here are some of the official pictures from the meeting. Here are the results of a survey of a wider sample of the world's population, mainly from G8 countries, indicating serious concerns. Here's the BBC's in-depth coverage and lots of links. Here also is a protest site against the G8 summit, to which various organisations and inidividuals contribute, here's British-run orgniasation Dissent's site and here's Indymedia's coverage of the same, including video clips etc.
