Bolivia's World People's Summit on Climate Change and the Rights of Mother Earth was radical, inspiring, uncompromising and exactly what was needed. Up to 30,000 people from six continents took part in the summit, which was held in the Bolivian city of Cochabamba from April 19 to 22. The huge oil spill from a BP rig in the Gulf of Mexico underscores the summit’s significance. About 800,000 litres of oil are spewing out a day. The company admits it may not be able to stop the leak for weeks — or even months.
