This week on Sea Change Radio, we revisit a couple of discussions from last year. First, host Alex Wise speaks to Gareth McKinley, an MIT professor whose students have come up with a potential solution for the rainless days that await many regions as climate change takes hold – a technology that effectively converts fog into potable water. Then, we hear from Marion Nestle, a noted nutritionist and author whose latest book digs into the power of cartoons to drive home complex arguments for fighting food insecurity issues in this country.
