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.
