Chop chop sticking

So in the past few years i had started bringing my own chopsticks whenever i go out for sushi. some friends shake their heads like i'm some nerd. but really, and seriously...
In China alone, 45 BILLION chopsticks are thrown out a year! 25 million trees are destroyed!! Would you not find it strange if you went out to a nice restaurant and for cutlery, you would get disposable plastic fork and knife? So why is it ok with chopsticks?
Seriously.
