You’re one year older and you wake up to a big surprise– your friends are blindfolding you and taking you out to a birthday treat! You drive for a while, walk a couple of blocks, take off your blindfold and find yourself in a grassy park with a cake in front of you. Lucky you! However, you’ve never been here before, so how do you know if you’re actually at a new place or just in front of a huge, detailed picture?

Well, it’s not that likely that you’d be brought to a place where there is such a large image, but being able to tell the difference between a complicated 2-dimensional picture and a 3-dimensional place with objects is something we often take for granted. Thanks to what are called depth cues, we can use these hints to tell that a tree is farther back behind another tree, and not equally far from you as they would be in a flat photograph.

Deep in the Amazon rainforest in Brazil, there are no cities or roads. The only way to get in is by boat or with a special kind of airplane that can land on the water. The foliage is so thick that you can barely see the sky when you’re underneath the trees. And the few people that live there live very different lives from people in the United States, or even people in the rest of Brazil. They can go for months or even years without ever seeing people from outside the jungle. Because they live so far from civilization, they don’t need to have jobs or money. They get what they need to eat by picking it off trees, catching it in the water, or hunting it with bows and arrows. When they need to sleep, they go to huts made of palm leaves with dirt floors and use thin tree branches as a bed.
