Marcelo Moreira, Amapá's environmental prosecutor, says that port issues have become common in nearby Amapá.

Amapá is a port of entry for ships that generally transport grain and ore.

They stop at the local port, and we already know there are impacts there.

But he says for Santana, this is a new and rapidly increasing problem.

On Santana Island, I don't think they even realize the magnitude of the impact.

Santana Island has been inhabited since the 18th century.

It was a longstanding settlement, but it's an impoverished one.
