Here is my PSA:

Have you ever heard of PSA’s? Well if you haven’t, a PSA stands for Public Service Announcments. It’s basically a ad for something that is endangered like ecosystems or maybe like wasting water or like don’t smoke. In our class, we had to make our own PSA and we had to choose one of the ecosystems that is endangered. Our time limits were 30 seconds or 1 minute.
