• Climate change, biodiversity loss and pollution add up to three self-inflicted planetary crises that are closely interconnected and put the well-being of current and future generations at unacceptable risk. • Ambitious and coordinated action by governments, businesses and people around the world can prevent and reverse the worst impacts of environmental decline by rapidly transforming key systems including energy, water and food so that our use of the land and oceans becomes sustainable. • Transforming social and economic systems means improving our relationship with nature, understanding its value and putting that value at the heart of our decision-making.
