No more than: " Hey all you adults out there. You need to save my planet for me. "
That's a pretty reasonable request for a child to make. It's like a kid in a car asking the adult driver to not drive so recklessly.
Someday, her generation will be in the driver's seat. But for now, our generations are driving the world, not her generation. So asking us to not recklessly cause so much damage is pretty reasonable.
