Kenya, a country in East Africa, is known for its amazing wildlife, especially lions. However, over the last decade (十年) the number of lions has decreased from 10,000 to over 2,000. Most of them were killed by the local people because they had to do so to protect their cows.

As well as the cows, wild animals should be protected. Now because of a creative idea thought of by a young boy, this problem can be solved peacefully.

At the age of 11, Richard Turere was put in charge of the family’s cows. The local people think this job is an honor since cows are considered the family fortune.

The only problem was that their land was next to Nairobi National Park, home to the largest number of lions in the world. As a result, the cows were often eaten by the hungry lions.

Richard noticed that when he walked around the cows with a flashlight, the lions kept away because they were afraid of humans and the flashlight. So he decided to create an automated (自动的) flashlight. Richard tied some bulbs (灯泡) from broken flashlights around the cow stockade (栅栏). Under an automated lighting system, the bulbs flashed one by one, just like someone walking around with a flashlight that could keep lions away. 

Since Richard’s invention was put to use, none of Richard’s cows has lost. As it only costs $10 to make this simple device, it can be widely used in Kenya in the future.
