Have you ever tried to come up with ways to solve a problem in your community? Wangari Maathai worked to solve an environmental crisis and help people at the same time.

When Maathai was young, it was unusual for girls in Kenya to go to school, but she was determined to learn more about science and nature. As an adult, she noticed that people were cutting down too many trees. Maathai knew that forest loss was bad for the health of the environment and people. She started the Green Belt Movement, which educated women in rural villages and paid them for every tree they planted. The program helped plant millions of trees and brought money to the villages. For her environmental and human rights work, Maathai became the first African woman to receive the Nobel Peace Prize.
