The town has been off-limits to cars since 2002, as there is no space for cars on the island where the town is located. It has been called the Venice of the Amazon, because many of the homes are on stilts and the town is only accessible by boat, though there is an airstrip in town which is often underwater. The town's mayor has described it as a model for net-zero emissions.[2]
