Climate change is the greatest threat facing the planet today. We all need to make changes to our lifestyle so that we live more sustainably. But individual action alone will not make the deep cuts in greenhouse gas emissions in the critical ten years we have left to avoid catastrophic climate change. We need Governments to facilitate the nation-wide changes that are required and policies that will protect the ecosystems on which we all depend. To deliver greener homes, gardens and cities; more sustainable food production and transport systems, we need a new politics, politicians prepared to act and voters prepared to reconsider the priorities which underpin their vote.
