In Alaska, the US, the grizzly bears are not alone because of Timothy Treadwell. Everyone knows that grizzly bears can be very dangerous to people. However, people can be perilous to grizzly bears, too, because their fur and food are beneficial for some people. In fact, half of the grizzly bears die before they are five years old, even though they can live for about 30 years.

Grizzly bears hibernate every winter. They sleep for several months. During this period, they don’t wake up or eat anything. When they wake up in the spring, the grizzlies are in danger. But Timothy can protect them. He sleeps in a tent near the bears and bathes in a river with them. People do not hurt the bears when Timothy is with them.

Timothy went to Alaska for the first time about 17 years ago. He was attracted by the beauty of the land and the prettiness of the animals. When he learned that people kill many grizzly bears every year, Timothy determined to protect the grizzly bears and to keep the bears safe from danger, so he lives with the bears for four to five months every year. At the beginning, Timothy’s parents didn’t agree, but later, they firmly supported him to do so, because they also wanted to protect bears as him.

Timothy has lived with the grizzlies every spring for about 17 years. Some bears are now his friends. He gave them names. His friend Booble sometimes gives him fish which he likes. His friend Lazy sleeps near his tent every night. Every winter, when the bears hibernate, Timothy returns to his home in California. Then he teaches children and adults about his friends in Alaska.
