give them a dollar every time a teen recycled or tell them that girls dig guys that recycle
Let them litter so much that school will get very dirty and ask "is it funny to study here now?"
Bribe them
I have to write a geography report on how to make our school more energy efficient but I can't come up with a solution to the problem teenagers don't bother with recycling. I have no idea what I should write. So how do you make teenagers recycle?
