# Today is World Environmental Health Day, observed under the theme, Clean Air, Healthy People. This day encourages collaboration between public and private institutions to implement sustainable practices, reduce pollution, and adapt to climate change to protect public health. Globally, approximately 99-percent of people breathe air that exceeds World Health Organisation safety guidelines, exposing them to dangerous pollutant levels. International Federation of Environmental Health says sustainable practices and policies can mitigate the effects of air pollution and improve people’s health and well-being.
