Each time I run the 30 Day Sustainability Challenge it is different. Now that I run them on YouTube, they are there for anyone to participate and start the challenge at any time. Here are Days 6-10 from the August/September 2021 cycle that you can watch when you are ready to join. Also, feel free to join an upcoming cycle--each time they are different and tend to focus on somewhat different topics. I'll run another one starting in October or November. Here's a link to Days 1-5.
