Tunley Environmental’s Post

Thirty seven years ago, on September 16th 1987, government representatives from all over the world gathered in Montreal Canada to agree on an international treaty designed to restore the ozone layer—This treaty, the Montreal Protocol would go on to be hailed as one of the most successful examples of global environmental conservation efforts. What is the ozone layer? The ozone layer is a thin, yet crucial, layer in Earth’s stratosphere that acts as a protective barrier, absorbing harmful ultraviolet (UV) rays from the sun. This shield works by filtering out 97-99% of the sun’s damaging UV-B and UV-C radiation, allowing only the necessary sunlight to reach Earth, keeping our ecosystems and human health in balance. Without it, life on Earth would be at risk of increased UV exposure, leading to serious health and environmental impacts. Human activities, particularly the use of chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) in refrigeration and aerosols, began depleting the ozone layer in the 20th century. Since the signing of the landmark Montreal treaty, the ozone layer is well on its way to recovery with the UN estimating that it is expected to return to pre-1980 levels by the middle of this century. On World Ozone Day, we celebrate the achievements of international cooperation in saving our planet’s silent shield. It’s a reminder that when we act together, we can heal the planet and safeguard our future. #WorldOzoneDay #SaveTheOzone #EnvironmentalSuccess #SustainableFuture #Sustainability
