Our environmental organizations win many battles, but we are losing the planet. Forty-six years after the first Earth Day, we find ourselves on the path to a ruined planet, not one sustained and whole. The hard data on climate, biodiversity, water and more are truly frightening. Clearly, more of the same environmentalism is not going to do the job. We have had huge growth in the size, sophistication and resources of our leading environmental groups. So, clearly, something new is needed – a new environmentalism that offers hope of finally turning the corner before it is too late. To discover this new approach, we have got to ask again: what is an environmental issue? The answer puts us on the search for a new more joyful economy.
