why cant a teenager chose to care about environment??

why isnt she like other kids eat MC, play games and get fat
or backpacking through europe
or getting drunk partying, getting pregnant

because she chose a different path...

calling her creepy just shows ignorance.... she has Aspergers,
"People with Asperger's syndrome normally speak uninhibitedly, but may express themselves in a formal and stilted way, sometimes making unusual use of language. Normally they are averagely or even highly gifted, but they are often very unevenly gifted. Asperger's syndrome shares many of the traits characteristic of autism."
