Air Pollution PSA

I did a PSA on air pollution. This is affecting everyone in the world including Philadelphia. I chose air pollution to do a PSA on because I figured that would be a good topic to give information on because unlike some of the topics, everyone needs the air and oxygen. I didn’t focus directly on Philadelphia because anything I said can also be said for other parts of the world. I learned how many people are actually affected by air pollution when I thought of just major cities that were affected.
