A colossal, lush rainforest that spans the width of South America, stretching from the shores of Brazil to the craggy mountains of Peru.The Amazon is bursting with life – nearly one in ten of the world’s species lives in this rainforest, with potentially thousands of plants and animals that have yet to be discovered. Before 2005, the rainforest was under significant threat from cattle ranchers and farmers, who clear vast tracts of land to farm profitably. But preservation efforts have reduced the damage that the forest sustains, and since 2006 serious gains have been made in safekeeping the Amazon. It’s worth a visit to behold the green twilight underneath the vast trees, take a zip line through the luscious canopy, and see all the exotic plants and animals.
