Trans-Brazil trail raises hopes for Atlantic Forest

RIO DE JANEIRO - Luiz Pedreira walks with other hikers beneath the Atlantic Forest's thick canopy in Brazil, where an 8,000-kilometer trail stretching the full length of the country is being opened up.

He says he hopes that the creation of the trail, one of the world's longest, will raise awareness about the fragility of the forest - long devastated by loggers and farmers.

"If you don't know something, you don't value it," says Pedreira.
