Difference Maker Álvaro Cogollo uses popular music to entice Colombians to love nature

Biologist Álvaro Cogollo draws on Colombia's native vallenato music to inspire a love for his country's biodiversity.

As a boy growing up on a farm near the Caribbean coast of Colombia, Álvaro Cogollo loved the forest. His grandfather taught him the common names of the plants, trees, and animals, and Mr. Cogollo would disappear for hours with a notebook, recording the explosion of life he found there.
