Can these seedballs solve Kenya's deforestation crisis?
"Manati!" A hundred pairs of eyes widen as Teddy Kinyanjui pulls out a makeshift catapult (or 'manati' in Swahili) to show children at Kwamwatu Primary School today's nature lesson.
Teddy explains the importance of trees as food, shelter and fuel but also how they protect crops and plants from the wind and soil erosion that is turning Machakos county and much of Kenya into a dustbowl.
Teddy is co-founder of Seedballs Kenya.
He holds up a small, black marble-sized pellet: a single tree seed coated in a charcoal shell to stop it from being eaten by insects and animals.
