From there she has travelled various African countries to observe how people are dealing with deforestation. As a story teller she feels that there is a great community of people out there committed to change their behaviors to protect forests and thereby creating new livelihoods that can lift them out of poverty. Telling their stories will help outsiders, the public, to connect with what’s happening in the world and boost their motivation to join in to protect their environment.

For every photo posted during the challenge, we will plant a tree and do our part to support the restoration of one of the most deforested countries in the world.
