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. On the way out, I asked them to wait while I ran up to EL Capitan, a 36 rock of 3,300 feet straight up. I touched that giant rock and knew 37 I wanted to climb it. That has been my life’s passion ever since— 38 the rocks and mountains of Yosemite. I’ve long made Yosemite my 39 .
About 15 years ago I started seeing a lot of 40 , like toilet paper, beer cans, and empty boxes, around the area. It’s 41 me why visitors started respecting the place 42 and treated such a beautiful home-like place this way.
I tried 43 trash myself, but the job was too big. I would 44 an hour or two on the job, only to find the area trashed all over again weeks later. Finally, I got so 45 it that I decided something had to change.

Over three days we collected about 6,000 pounds of trash. It was amazing how much we were able to 49 . I couldn’t believe the 50 we made —the park looked clean!
Each year volunteers come for the cleanup from everywhere. In 2007 alone, 2,945 people picked up 42,330 pounds of trash and 51 132 miles of roadway.
I often hear people 52 about their surroundings. If you are one of them, I would say the only way to change things is by 53 rather than complaining. We need to teach by 54 . You can’t blame others 55 you start with yourself.
