Here is an video from Youtube... a lady picking up trash in the beach... one person doing such a small activity can help the entire world... a tiny difference , and  especially this is a woman. The ones to make important milestones in the world don't just have to be boys! Girls can make milestones and be scientific too! This doesn't have to just be in Key Biscayne... this can also be al around the world. And this is in Mexico... but still! YOU can change the world with a tiny difference!
