The sun shines brightly through a halo of clouds over Knoxville, Tennessee, in the United States of America. Saturday's #OzoneDay celebrates the landmark 1987 #UnitedNations agreement, called the 'Montreal Protocol', which helped phase out the production and use of ozone-depleting substances to protect the ozone layer. The ongoing healing of the ozone layer is an inspirational example of how the international community can come together to address global challenges. It demonstrates that through joint #ClimateAction, we can win the race against the climate crisis. From driving less 🚲 and buying local products 🍎 to avoiding harmful cleaning products 🧼, each of us can help protect the ozone layer. ⬇️ Tell us in the comments below how you are taking action to protect our planet and shared future! 📷: UN Photo / R Kollar #GlobalGoals #ActNow
