Discovery of the hole in the ozone layer: environmental awareness and fighting scientific fake news

In the 1970s, the discovery of the problem of the hole in the ozone layer represented a crucial milestone in the history of science and the environment. Scientists such as Mario Molina and F. Sherry Rowland revealed that chlorofluorocarbons (CFCs), previously thought to be harmless, could destroy the ozone layer, leading to global awareness of environmental protection. However, they faced resistance from industry and misinformation. Confirmation of the problem came with Jonathan Shanklin’s work in Antarctica. The effects of ozone depletion, such as increased skin cancer, were documented, and humanity reacted with the Montreal Protocol, phasing out harmful substances. Furthermore, the link between the historical success of science-based environmental actions and the modern challenges posed by misinformation should be emphasized, especially considering the rise of digital platforms as both tools and threats to public understanding. Today, tackling disinformation in global environmental problems represents a substantial challenge, requiring science education, raising awareness on social media, valuing traditional sources, training in source verification, recognizing science as a reliable source, and tackling environmental challenges based on science. This article proposes actionable solutions such as integrating critical media literacy into education, establishing international regulations to curb disinformation, and leveraging collaborative platforms to promote accurate scientific communication. It argues that strengthening international cooperation, modeled on the Montreal Protocol, is crucial to countering misinformation and fostering effective global environmental policies. The history of the Montreal Protocol highlights the importance of science, international cooperation, and determined action in protecting the environment and human health.
