“A senior American diplomat has cautioned that Indian cities, including Kolkata and Delhi, may have difficulty in retaining and attracting talent if they do not clean up the air. Speaking to TOI, US embassy deputy minister counselor for economic, environment, science and technology Samuel Kotis said high levels of air pollution was a growing concern among expatriates. “Air pollution affects everyone because we all breathe the same air. Its adverse impact on health is definitely cause for concern. As a father, I am worried about my son who is 16. On days when the pollution level is very high in Delhi, I ask him to stay indoors. I am sure parents in Kolkata would be concerned as well because there are days when the air here is more polluted than Delhi,” Kotis said.” The Times of India (Kolkata edition).
