What are some good visual aids for a presentation on pollution?

To reduce pollution, we need to use renewable resources such as: Hydroelectric Power, Solar Power, Wind Power, and Geothermal Power. Most people use non-renewable sources. The most common non-renewable resource is coal. When cars drive, they let out non-renewable steam from gas. That is another non-renewable resource. If we change our world to renewable resources, than all of us will be safe from cancer. Less pollution, the longer we live.
