Technological innovations, such as hybrid cars and low-emission engines, are making a difference. The West Coast Maritime industry is working to address diesel pollution, with the Port of Seattle converting vehicles to biodiesel, using low-sulfur fuels, and providing onshore electrical grids for cruise ships. However, the video concludes by emphasizing that technology alone is not enough; personal commitment is essential to clean up the environment.
The video introduces Jordan Petty, a 12-year-old with asthma, whose struggles to breathe are exacerbated by airborne irritants. It reveals that outdoor air pollution contributes to hundreds of deaths and hospitalizations annually in BC and Washington State, emphasizing that air pollution is not just an irritant, but a killer.
Residents of the Georgia Basin-Puget Sound region share a common air shed, meaning pollutants travel across borders. Vehicle idling is highlighted as a significant contributor to greenhouse gases and toxic chemicals. Turning off an engine when idle for more than 10 seconds can improve air quality and save gas. While visible pollution is concerning, unseen pollutants cause the most harm. Transportation is the primary source of air pollution in cities, and the increasing number of cars negates the benefits of low-emission engines.
Beyond cars, small engines, especially two-stroke gasoline engines in older lawnmowers and leaf blowers, are significant polluters. An older lawnmower running for an hour can emit as much pollution as a new car traveling 550 km. Diesel trucks, buses, construction equipment, and ships running on heavy bunker fuel are also major sources of pollution, with their long operational lives meaning these fleets will take time to replace with cleaner alternatives.
In rural areas, smoke from wood stoves, backyard burning, and land clearing is a major concern. David and Rosemary's story illustrates this; Rosemary, who has severe breathing problems due to asthma, moved to the Sunshine Coast for cleaner air but found her health impacted by neighbors' wood stoves and traffic fumes. This led them to form the Sunshine Coast Clean Air Society to educate their community.
Rosemary's condition is aggravated by particulate matter, fine solids that remain in the air and carry toxins like Benzene. Particulates less than 10 microns (PM10), like pollen and dust, and especially those less than 2.5 microns (PM2.5), are dangerous because they can be easily inhaled and penetrate deep into the lungs. Larger particles are filtered by the nose, but smaller ones reach deeper into the respiratory system.
