Spanning nearly 7 million square kilometers, it is difficult to conceptualize just how vast the Amazon rainforest is. Here, the Tiputini River winds its way through a tiny corner of the Amazon Basin in eastern Ecuador, eventually emptying its waters into Peru, Brazil, and then the Atlantic Ocean nearly 3 thousand kilometers away. Having lost nearly 20% of its forest cover in recent decades, the Basin is still under siege today from threats such as mining, oil drilling, and clearing for farming. Despite these losses, much still remains intact and just as imperative as ever to continue protective efforts for these invaluable forests. Yasuní National Park, Ecuador.
