For more than twenty years, Bill Nye "the Science Guy" has inspired legions of fans with an empowering message: The combination of scientific curiosity and human ingenuity can transform obstacles into opportunities and unlock a future of endless possibilities. Now, Bill applies his message of technological optimism to one of the most serious challenges facing our species: climate change. With a scientist's rigorous understanding of how things are and an engineer's vision of how things could be, he completely reframes the issue of today's environmental crisis, and views it not as the end of progress but as an opportunity for a tremendous new beginning--a moment for our society to rethink the way we live and to create a cleaner, healthier, smarter world. We need not remain shackled to the inefficient technologies of the Industrial Revolution; we need not accept pollution and environmental ruin as the inevitable costs of a vibrant economy; above all, we need not leave our children a planet that is depleted and overheated. The urgent task here is not saving the Earth--it's saving the Earth for us, for humanity. We can do that, but the moment to begin is now.-- Adapted from book jacket.
