JPE250 – CHAPTER 1 NOTES
In Canada, provincial law provides the basis for environmental regulation and protection
Canada’s population in 2014 – 35.5 million but second largest by landmass and largest by
coastline
Canada is huge – but sparsely and unevenly populated
Touches 3 oceans: Arctic, Atlantic, Pacific
Largest intact forest in the world: boreal forest – includes a subarctic boreal region called a taiga
(begins where the tundra ends) and has mostly spruce and fir trees that can withstand cold
climates
Environmental quality varies from region to region and is affected by several factors (population
density, climate change, political activity)
ENVIRONMENTAL QUALITY AND INDICATORS
2008 – federal government passed the FEDERAL SUSTAINABLE DEVELOPMENT ACT – mapped
out sustainable growth across Canada’s economy
Tracks 9 environmental indicators and issues annual reports (GHG emissions,
weather warning index, various air quality indicators, measurements of
freshwater quality in rivers, water quantity in rivers, environmental quality of
Great Lakes, protected areas, ecological integrity of national parks and of major
fish stocks)
AIR QUALITY
Measured by testing levels of major pollutants in air: nitrogen dioxide, sulphur dioxide, carbon
monoxide, ozone, and particulate major
Come mainly from vehicle emissions and industrial sources
WHO ranked Canada 3 rd
in an air quality index
Whitehorse = best, Sarnia = worst, thus varies by region
Indoor air pollution a major concern as people spend 90% of time indoors
2 categories: biological (mould, bacteria, dust mites) and chemical (gases,
particles)
Natural sources of air pollution (radon) not regulated by government
In Canada, CO2 levels are getting worse, but ozone is getting better
