By the end of this century, if emissions keep rising, the average temperature on Earth could go up another four to eight degrees, what I'm saying is the planet's on f *** ing fire. There are a lot of things we could do to put it out -- are any of them free ? No, of course not. Nothing's free, you idiots. Grow the f ** k up. You're not children anymore. I didn't mind explaining photosynthesis to you when you were 12. But you're adults now, and this is an actually crisis, got it ? Safety glasses off, motherf *** ers.
