I fell in love with Yosemite National Park the first time I saw it, when I was 13. My parents took us there for camping.

That has been my life’s passion (钟爱) ever since--- ___18___ the rocks and mountains of Yosemite. I’ve long made Yosemite my ___19___.
About 15 years ago I started seeing a lot of ___20___, like toilet paper, beer cans, and empty boxes, around the area. It’s ___21___ me why visitors started respecting the place ___22___ and treated such a beautiful home-like place this way.
I tried ___23___ trash(垃圾)myself, but the job was too big. I would ___24___an hour or two on the job, only to find the area trashed all over again weeks later. Finally, I got so ___25__ it that I decided something had to change.
