Don't Eat With Your Hands

4 segments
On today's show: why cashing in on global warming may become the great game of the 21st century. We'll also find out about a remote Israeli village where all residents - both hearing and hearing-impaired - communicate by a unique form of sign language, and what that reveals about the connection between language and the brain. Plus: one man's cross-country journey to find the best food America has to offer, from fast food to organic produce. Also, a cookbook that helps vegetarians and meat-lovers eat together.
