Reviews
I found 'The Ozone Layer' course really informative for grasping how crucial this invisible shield is. The explanations of its formation and the threats from human activities, especially CFCs, were clear and helped me connect the science to real-world impacts. While the recovery efforts were covered, I wished there was a bit more detail on the specific ongoing challenges regions still face in monitoring and enforcement.
This course offered a solid overview of the ozone layer's vital role and the success of global recovery efforts. I would have appreciated a bit more on future technological innovations to monitor ozone depletion, but overall it was very well presented.
