Chronic exposure to air pollution from greenhouse-gas-emitting activities is killing an estimated 7,142 Canadians a year, and 2.1 million people worldwide.

More frequent heat waves contribute to heat stroke and more intense pollen seasons, which can aggravate allergies and asthma, as can forest fires.
