Miranda Lynch believes a vegetable garden can change the world.
It all started in 2008, when she visited the remote village of Inzinga, South Africa, with her dad. Just 12 years old at the time, she developed an unlikely friendship with a group of children at a local crèche, or preschool.
"When I first realized just how poor and malnourished and the situation they were in was in that crèche," Miranda says.
She soon learned that the villagers' struggle with education, poverty and disease was all related to their malnutrition, and she decided to do something about it.
“I told my dad I never want to leave this place without the intention of coming back. I want to keep giving, and I want to be a part of these people’s lives. And I also want to help them become independent and to become healthy,” she says.
So Miranda started the nonprofit Isipho, which means “gift” in Zulu, to provide fencing, seeds, tools and training to families and schools in Inzinga so they can grow their own vegetable gardens, "creating a new cycle of independence and hope and love instead of dependence and malnutrition."
Now a college student, Miranda has gone back to South Africa every year since her first visit, and she is overwhelmed by the change she has seen in Inzinga.
“The village is completely blooming and self-sustainable, and it’s amazing,” Miranda says.
