At the core of the encyclical is both a concern for the health of the planet and for the earth’s poor, reflected in a commitment to social values and integrity, environmental resilience, and economic inclusion.
The stock-taking begins, aptly, with pollution: “Some forms of pollution are part of people’s daily experience. Exposure to atmospheric pollutants produces a broad spectrum of health hazards, especially for the poor, and causes millions of premature deaths.” The World Bank’s latest edition of the Little Green Data Book finds indeed that in low and middle-income countries, 86% of the residents are exposed to air pollution levels (measured in exposure particulate matter less than 2.5 microns in diameter) that exceed World Health Organization (WHO) guidelines. The WHO last year made headlines when it calculated that 7 million people had died prematurely from indoor and outdoor air pollution in 2012. From safer cookstoves in rural areas, to better air quality management in fast growing cities, this is an area where solutions are known and must be urgently applied.
