Greenpeace activists form a banner in the landscape to highlight the link between Sydney's water shortages and climate change. The dam's water level has dropped from 86% to 39% capacity in the last 3 years. Warragamba dam supplies 80% of Sydney's 4 million people's drinking water.This protest was coordinated the day before the implementation of the Kyoto protocol agreement which will legally bind governments around the world to reduce or limit their greenhouse gas emissions.
