| So I hear you're doing a project on Air Pollution? | |
 | |  |
|
 |
| | |
| Yes. BoBo, that I am. Would you like to hear about it? | |
| | |
|
|
|
|
|
|
|
| | |
| Sure.. er.. What causes air pollution? | |
| | |
|
|
| | |
| Contamination of the atmosphere by wastes. Radical eh? | |
| | |
|
|
|
|
|
|
|
| | |
| Well.. I did not know that Sebastian, is there more? | |
| | |
|
|
| | |
| Well of course BoBo! There are two types, primary and secondary. Primary is caused by human activity and secondary is caused by CFC's and gasoline. | |
