Exploratory oil drilling off the coast of Brazil's Amazon rainforest are reshaping life in Oiapoque, a small city in the poor state of Amapa that is receiving thousand of migrants looking for work. Newcomers are clearing forest for makeshift housing as they wait and hope for jobs that may result from the drilling being done by Petrobras, Brazil's state oil company. While the prospect of economic opportunities is bringing hope, the impacts of unplanned urban growth in a city with already poor infrastructure are being felt. Environmental groups warn a spill could devastate fisheries and wetlands while Indigenous leaders also fear the project threatens their territory and way of life.
