Why is plastic pollution a big problem?
Marine species ingest or are entangled by plastic debris, which causes severe injuries and death. Plastic pollution threatens food safety and quality, human health, coastal tourism, and contributes to climate change.
How dangerous is air pollution in Canada?
Nitrogen dioxide and PM2.5 can inflame air passages and trigger asthma attacks, heart attacks and strokes. Health Canada estimated last year that more than 14,000 Canadians die each year because of exposure to air pollution.
Why do some cities have worse air pollution than others?
“Cities known for heavy traffic or manufacturing ultimately will have worse air quality than others, but environmental factors like proximity to mountains or an ocean breeze can trap and also sweep away air pollution,” said Dr. Ted Myatt, ScD, a senior scientist at the leading environmental consulting company Environmental Health & Engineering.
How is air quality ranked in Canada?
Once each city was scored, an overall ranking of air quality was determined. For the air quality rankings, a ranking of 1 corresponds to the city with the best air quality while a ranking of 50 corresponds to the city with the worst air quality relative to other cities in Canada, which is typically cleaner than many cities world-wide.
Is air quality an acceptable level of pollution?
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Members of sensitive groups may experience health effects.
