Some argue we should get coal, oil and gas out of the ground as quickly as possible, build more pipelines and make as much money as we can selling it here and abroad. Their priorities are the economy and meeting short-term energy needs so we can live the lives to which we've become accustomed.

Beyond reducing individual use, one of our top priorities must be to move from fossil fuels to energy that has fewer detrimental effects on water supplies and fewer environmental impacts overall.

Conventional economics is a form of brain damage. Economics is so fundamentally disconnected from the real world, it is destructive.

With an estimated population of nine billion people by 2050, we cannot continue to consume resources at the same rate and maintain our quality of life.

If America wants to retain its position as a global power, its president must listen to the people and show strong leadership at this turning point in human history.

It is clear that while science provides insights into the complexity of the world around us, those insights...present a fractured mosaic rather than a seamless whole. There are profound limits to science that must be recognized if we are to minimize the destructive consequences of using the powers provided by scientific discovery.

Over and over, we hear politicians say they can't spend our tax dollars on environmental protection when the economy is so fragile.
