Next week on the Exchange, we bring you some of our very favorite past programs. We’ll begin with a new definition of poverty, and why it’s creating some political waves. Then we look at the controversial but growing practice of fracking as a source for natural gas. We talk to Harvard Professor, Lawrence Lessig who asks why 'fundamentally good people, with good intentions, allowed our democracy to be co-opted by outside interests?" Later, Dartmouth doctor Ira Byock talks about end-of-life care, and his book “the best care possible”. And we end the week with an environmental author…on how much of what you thought you knew about protecting the planet is wrong. Join us all next week for the Exchange every morning at 9, and again at 8 pm here on NHPR.
