WHAT SHOULD WE BE WORRIED ABOUT?
I've really come to look forward to these annual collections from contributors to Edge.org, the multi-disciplinary science website. Every year editor John Brockman throws out a question to scientists of any discipline to address. The responses are short essays you can snack on like brain-stretching popcorn.
This year the responses are ones that may keep you up at night, so be warned. All of the contributors address the question of what the real threats to our planet and way of life are, as opposed to the false fears that distract us too easily. The topics range all over the scientific map; the likelihood of war, advances in medicine and health care, population growth and distribution, the advance of the virtual, global economics...you get the idea.
