A safe, healthy environment is a human right. Yet, 99% of us breathe polluted air, impacting every aspect of our lives, from our health and economy to the environment and social equity. “Pollution is a silent killer that can be stopped,” said #UnitedNations Secretary-General antonioguterres on Saturday’s #WorldCleanAirDay. The good news is that air pollution is a ⁣preventable problem and each of us can do our part with simple #ClimateAction steps, such as planting trees or commuting without polluting. 📸: Svjetlana Tadić, wmo_omm 2022 Calendar Competition #CleanAirNow #ActNow #GlobalGoals
