Climate change, you've heard of that. But climate justice? The Global Justice Ecology Project describes it: "Climate justice is the understanding that we will not be able to stop climate change if we don't change the neo-liberal, corporate-based economy which stops us from achieving sustainable societies. The historical responsibility for the vast majority of greenhouse gas emissions lies with the industrialized countries of the Global North. The production and consumption habits of countries like the United States continue to threaten the survival of humanity and biodiversity globally. It is imperative that the North urgently shifts to a low carbon economy."
