Just as fossil fuels from conventional sources are finite and are becoming depleted, those from difficult sources will also run out. If we put all our energy and resources into continued fossil fuel extraction, we will have lost an opportunity to have invested in renewable energy.

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.

The terrible part of this looming catastrophe is that people have been working on solutions for years and have developed concrete steps to massively reduce our energy use, while stimulating whole new industries and technologies that are more efficient and affordable.

I see a world in the future in which we understand that all life is related to us and we treat that life with great humility and respect. I see us as well as social creatures, and when I began to look back and say, ‘what is the fundamental bottom line for us as social creatures?’I couldn’t believe it because it seemed so hippy dippy, but it was Love. Love is the force that makes us fully human.

If we continue to set human borders and the economy as our highest priorities, we will never come to grips with the destructiveness of our activities and institutions.

Wind power, if not properly planned and sited, can harm birds and bats (although Danish studies of 10,000 bird kills revealed that almost all died in collisions with buildings, cars and wires; only 10 were killed by windmills). Alternative energy sources are absolutely necessary. Global warming will kill birds and bats, as well as other species, in much greater numbers than wind power.

Think about a seed. Once it lands, it's stuck. It can't move to find better soil, moisture or sunlight. It's able to create every part of itself to grow and reproduce with the help of air, water and sun.
