Bat mitzvah project? Community service?

[?Brunette~Ballerina?]

I want to do something hands-on! & something nobody else has done! something that i really care about, not just recycling! Here are things i care about...

-Saving our environment
-Protesting war
-Animal Cruelty
-Helping self-destructive teens (TWLOHA, search it, that's what i mean)

I'd really like to do something like making T-shirts protesting things like global warming & war & stuff & sell them & then donate them 2 a Charity like TWLOLA, PETA, Invisable Children, & WWF! Is that a good idea for my project? Like, is that acceptable?

So i want to know....
Is my idea is good?
What did other ppl do?
If my idea isn't good, do u have any suggestions?
