Michael Brune, the Executive Director of the Sierra Club, joins Aaron to talk about how to bring about the clean, healthy world everyone wants to live in. He explains the Sierra Club is working to be more inclusive as it works to alleviate problems due to Climate Change. They discuss how much more our leaders in government and business should be doing to combat Climate Change by supporting organizations directly addressing these challenges, such as the Sierra Club. Brune also explains what he believes are the critically important implications of President Trump’s decision to remove the United States from the Paris Climate Accord and why he believes that decision is an abdication of leadership.
