    I'm a student from Chongqing, China. I am write to keep you informing of something about the severe situation that finless porpoises, a kind of rare and lovely animal, are facing with presently.

    It's because of human activities that finless porpoises are endangered. It's terrible that there are merely less than 1,000 finless porpoises live in China. However, it's high time that immediate measures must be taken. Don't you think so? If possible, how I hope you can help us by funding your project aiming at protecting finless porpoises! Under your financial aid, I am convinced fewer finless porpoises will survive. I would appreciate greatly if you could consider my application.

    Looking forward to your early reply.
