Слайд 3 Air Pollution
Humans are the main cause of air

pollution. Industry, including factories and power plants, burn large

quantities of fuel. Burning coal and petroleum releases sulfur oxides and nitrogen oxide into the air. Airplanes, boats, and cars burn petroleum, releasing carbon monoxide and carbon dioxide.

Слайд 4 Air Pollution
The waste in landfills releases methane. Sulfur

Air PollutionThe waste in landfills releases methane. Sulfur oxides, carbon monoxide

oxides, carbon monoxide and carbon dioxide, and methane all

have a very negative effect on air quality. These pollutants can also contribute to the greenhouse effect.

Слайд 5 Some air pollution is not directly caused by

Some air pollution is not directly caused by humans: for example,

humans: for example, animals emit carbon dioxide when they

breathe, and volcanoes release sulfur oxide. However, most air pollution is linked directly or indirectly to human activity. This means that air pollution can be best controlled by modifying human activity to burn a smaller quantity of fossil fuels.

4. What is

at least one negative

pollution?
A study has listed air pollution as the
cause of four percent of the deaths in the

6. What is something you could do to
reduce air pollution?
Answers should vary, but may include:
using less power (thus putting less
demand on power plants); using cars
less frequently; diminishing the amount
of garbage so there will be less waste in
the landfill.
