In New Brunswick, we are lucky to have fairly clean and healthy air compared with some places in the world. But we do create some air pollution and it can also travel to our province from other areas by wind and weather.
Air pollution comes in many forms - You may be surprised to know that air pollution can come from nature, but it's true. The smoke and ash from forest fires, pollen from plants, salt spray from the ocean and even a far-off volcano can change our air.
However, most air pollution is caused by the things that humans do. When we operate industries with smoke stacks, burn wood, or when we drive cars and other vehicles, pollution is released into the air. This smoke, fumes, and other material are called "emissions", because they are emitted or sent into the air.
Did you know that transportation causes about one-third of Canada's air pollution? Every year over 15 million cars, trucks and other vehicles travel on the roads across our country, including here in New Brunswick, and they produce "carbon dioxide" emissions. That's the gas that comes out of the exhaust pipe when a vehicle burns the fuel it needs to make it go. Carbon dioxide has no colour or smell but it can cause problems for our environment.
