Here's how Brazil is saving the rainforest by making 9 million condoms for the Olympics

Brazil is going to hand out 9 million free condoms around Rio de Janeiro during the Olympics, but not just to save people from unwanted pregnancies and STDs. They're doing it to save the rainforest too.

As Reuters reports, the condoms are being produced at Natex, a factory in the deep in the rainforest of the western Amazonian state of Acre, close to the Bolivian border. The rubbers are, quite literally, rubber, as the sustainably-produced condoms are made from wild Amazon rubber trees.

Here's how they're made, and how the factory is helping to protect the rainforest from deforestation.
