Answers to numbers (Somebody else do another half)
1. If I could do something I've never done before, it'd be sky diving. I would want to go sky diving for the thrill of falling and descending back to Earth from a great height. Also, trying new activities is awesome, so why not do as much as you can while you're still here?
2. Pollution is bad because it kills the environment and people around us. Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Humans are also regularly harmed by pollution. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases.
3. If I could go back to any place in time, I would stay right where I am. The world is already bad enough with political issues, protests, fires etc. Going back in time would do nothing but change the flow and disrupt how the world is working.
