In a village on the slopes of Mount Kenya in East Africa, a little girl worked in the fields with her mother. Her name was Wangari.

Wangari loved being outside. In her family’s food garden she broke up the soil with her machete. She pressed tiny seeds into the warm earth.

Her favourite time of day was just after sunset. When it got too dark to see the plants, Wangari knew it was time to go home.

She would follow the narrow paths through the fields, crossing rivers as she went.
