  • Great Show

    Love this show! The conversations are thoughtful, insightful and despite a background in environmental science and sustainability I learn so much every episode. My only issue is that Josh’s audio needs to be tweaked. Guests voices are always loud and clear but Josh’s voice is hard to hear - like you’re using your laptop mic and 4 ft from it. Fix that please, but otherwise keep these coming!

  • Forest products

    I enjoy the thoughtful podcast on the Sterling company and the mention of regenerative forestry. There is a professional certificate in sustainable forestry , and industry standard that makes sure forests will be there for generations to come. The professionals and the forest companies that qualify for this are doing reliable work for the economy and for the environment. Look for “sustainable forestry “ products.
