    Zeb Hogan is always traveling around the world to save endangered fish.

This famous ecologist(生态学家) grew up in a city in Arizona, America, but he had a big backyard with lots of trees. He spent his free time climbing trees and catching animals with his brother. They each had their favorite places in the biggest tree and they worked out ways to climb from tree to tree without ever touching the ground. Their family went camping in the summer and they would usually visit zoos and aquariums(水族馆) on their family vacations. His clearest memories as a child all had to do with animals and the outdoors. As he was older, he became interested in animal shows on TV and he would wake up early to watch Wild, Wild World of Animals before the other family woke up.

    One day when we talked about fish, he said, “As an ecologist, Mr. White, you should know that fish in most parts of the world have a hard life, such as the Mekong giant catfish, the Chinese paddlefish, taimen, and the Murray cod. They are all in danger and have to do with all kinds of challenges all by themselves. Water pollution is one of them. So these fish really need our help."
