The Earth is becoming warmer and warmer as a result of the toxic gases generated from the vehicles, forest fires, factories and deforestation. Planting trees can slow down the global warming process and climate change. It should be noted that the most affected gender by climate change is female. We go around communities in Uganda teaching them about climate change, global warming and donating a tree for planting to the girls ( aged 10-17) from that community that have enrolled with us. The enrollment ensures monitoring and evaluation. The concept of One Girl One tree, will see to it that communities can become greener, the temperature in the cities will decrease, and the trees will attract rain replenishing the decreasing water table. This is one campaign that will truly make the Earth a greener place to live in and make the world safer for girls and women.
