Itamar – Air Pollution

This is my presentation about air pollution.

As you can see in areas of South America and Australia  there is less pollution because there is a lot of jungles in those areas.

In north America  and Scandinavia there is a lot of places that no one live there so no  much air pollution.

But in China Europe and Asia there is a lot of factories and no so much empty place to live.

It happened when the air contains gases and dust in harmful amounts.
