Literse

First, thanks for making science class so great in middle school. I still have that theme song stuck in my head.

What is our worst case scenario assuming nothing gets done to save the world and what does the timeline look like? How much is my life going to be affected? My kids? I know we need to do something, but what if it doesn't work out?

I tan very easily and always wear high SPFs. Every once in a blue moon I get a bad burn where I forgot to apply sunscreen, or didn't apply enough.

Two questions. First, everyone always recommends Aloe. Is there any medical benifit to this besides reducing pain? Second, how much tolerance does our skin have before it becomes damaged and starts to look bad and or become dangerous? A couple bad suntans? Many?
