It has taken him 40 years, but Omar Tello has turned a patch of exhausted farmland in Ecuador back into rainforest. One of his biggest challenges was repairing the soil. His land was so degraded he had to make enough new soil - from unwanted wood shavings and chicken manure - to cover the entire plot. That alone took about 15 years.

He also travelled deep into the Amazon for days at a time, looking for seeds and plants he could rescue. Now his forest is flourishing and the wildlife has returned - it is home to snakes, toucans, monkeys and many other animals. And he is sharing what he has learned to encourage others to protect the rainforests instead of cutting them down.
