I'm not entirely sure I can repeat this again. We look at estimates from air pollution from industry, transportation, and other human activities, resulting in 14,400 premature deaths, but it's also the economic costs: $110 billion per year in socio-economic terms. When we look at the number of people, when we look at the coal phase-out in Ontario, we had 53 less smog days—53 to zero.
