This is a prequel to Soylent Green
It was not made as such, but it is a perfect prequel. The way the coup planners talk about the country and the resources there, they set the country up as one of the few untapped resources. Like the rest of the world has been stripped bear of raw materials. Zangaro and a few other places are the only places left to go.
One would suppose, about forty years after that, the world would be totally out of resources, and it would be the world of Soylent green.
