19．When I was little，I'd see tons of bats flying around streetlights at night in my neighborhood in upstate New York．
By the time I turned 7，I noticed something strange：All the bats in my neighborhood had vanished，and I wondered why．Later I learned what had happened to my town's bats．A disease called"white nose syndrome（白鼻綜合征）"had killed 93percent of New York State's bats （and about 6million bats across the country）!I was shocked．I asked the bat biologist what I could do to help，and she said，"Tell others what's been happening．Help people understand that bats are important to our environment and need to be protected．"
I thought I must teach people about bats．My first stop？The library，where I eventually checked out every book on bats they had．Next，I started a Facebook page called Buddies for Bats and posted any photos，facts，and videos that I could find．Then I wrote a letter to the host of an environmental program on my local radio station，asking if they'd do a show on bats．（They did!）
But I still wanted to find a way to educate people face to face．I managed to make a presentation to a school．I also used tools to describe how bats help farmers （and protect our food supply） by eating crop-damaging insects．
I practiced my presentation until it shone like a polished stone．It went over so well that other teachers started requesting me．Over the past three years，I've talked in front of everyone from 5-year-olds to senior citizens!The more I present，the more I notice that I am changing minds．I have watched people go from dismissing bats as"disgusting（令人厭惡的）"to truly understanding them and advocating their protection．
Right now，I'm thinking of becoming a marine biologist （海洋生物學(xué)家） someday．As long as I'm helping animals，I'11be happy．
