Meet the Journalist: Brian Castner

The Mackenzie River in far northern Canada is the second longest in North America, a massive watershed sometimes called the "Cold Amazon." Author and journalist Brian Castner paddled the length of the river in the summer of 2016, to report on climate change by speaking with the indigenous First Nations most affected by a rapidly warming Arctic. He found a people open to new technology and ideas, but dedicated to their traditional values, seeking a balance between conservation and exploitation.
