The human world sits on the brink of potentially catastrophic environmental change. If we do not drastically reduce greenhouse gas emissions, and start that process now, it is projected that in the second half of the 20th century the cost of climate damage could amount to a fifth of global GDP. The latest science confirms that there is now only a decade left for action. How Many Lightbulbs Does it Take to Change a Planet is a clarion call for urgent action in the face of environmental change that threatens to devastate human societies. In it Tony Juniper, director of Friends of the Earth for England and Wales, presents his programme for staving off environmental, economic and social disaster. His '95 articles for comfort, security and survival' embrace actions needed to reduce carbon emissions and protect the Earth's natural ecosystems, measures required to establish sustainable farming methods and conserve agricultural biodiversity, and wider economic reforms needed to create a proper economic context for environmental sustainability and to make quality of life - rather than growth in GDP - the target outcome of economic activity. Passionately written and cogently argued, How Many Lightbulbs Does it Take to Change a Planet is essential reading for anyone who cares about the world our children will inherit.
