Suddenly Jimmy has an idea...
|
|
|
|
 | |  |
| Maybe we could think of ways to prevent the pollution. | |
 | |  |
|
 |
| | |
| Yes, that's a very good idea! | |
| | |
|
|
|
|
|
|
|
| | |
| For example we could use glass bottles instead of plastic bottles... | |
| | |
|
|
| | |
| Yeah, glass bottles are more enviromental-friendly. | |
| | |
|
|
|
|
|
|
|
| | |
| Imagine the people would use their bikes instead of their cars... | |
| | |
|
|
| | |
| Yes, I know what you mean. | |
