India’s air pollution killing over a million a year

India’s toxic air is now contributing to nearly 1.1 million deaths a year, and the country is on its way toward standing alone as the site of the deadliest air pollution problem on the planet.

A new study on global air quality released a joint effort between the Health Effects Institute in Boston and the Seattle-based Institute of Health Metrics and Evaluation, states that from 2010 to 2015 the number of premature deaths caused by air pollution each year has gone from 957,000 to about 1.1 million in India.

Several factors—including rapid industrialization, a heavy reliance on coal for energy, population growth, and an aging populace make India the air pollution capital of the planet.
