I think she is amazing. She has already achieved in one year more than most of us have in long lifetimes. At sixteen the average kid can probably influence about a dozen others at most. Her words have informed and inspired people on every continent.
I wish people would take time to consider the enormity of what she is warning about, and drop the irrelevant, relentless criticism of her appearance, health, family, choice of transport etc etc. I just can't understand why people are objecting to being told that we are all in peril and need to change our ways in order to survive. Would you really rather bumble along in utter ignorance until it is Just Too Late???
