If we have any hope of finding ways for seven billion people to live well on planet with finite resources, we have to learn to use our resources efficiently. Plastic bags are neither efficient nor environmentally friendly.

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.
