July 4th

July 4th has just passed, and it's amazing to see all the colorful fireworks, but it's pollution to the air.  I'm not saying that fireworks should be banned all together, but public fireworks shows should be allowed, not private fireworks shows.  Have you ever looked up in the sky on July 4th and seen all that smoke?  Yeah, that's pollution.  All that smoke evaporates, but it still makes the air smell, and it sometimes makes the air hard to breathe.  If you do want to celebrate Fourth of July, just use sparklers, they're less noisy, and unlike fireworks, you can create any shape you want.  Either way, celebrate Fourth of July every year, and I hope you guys had a fun Fourth of July yesterday.
