Today I saw 3 air pollution presentations. Most of them were pretty good yet they all looked alike as we all talked about the same problems. Nevertheless, all were convincing and so was mine. Mine, which is the fourth presentation, was similar to the others. To tell you the truth, I got kinda sad to know that mine was like all others and not that original yet the pictures in all the presentations were original and funny. If I could do my presentation again, the only thing that I would add to it is more information so it would stand out a bit more. Nevertheless, they were all good presentations.
