Hell of the Living Dead 1980
It is also known as Virus, Night of the Zombie, and Zombie: Creeping Flesh
After a chemical leak at the Hope Centre in Papua New Guinea (an organization devoted to feeding underdeveloped countries) turns its staff into flesh-eating zombies, a four-man commando squad led by Mike London are sent to investigate. They run into a TV news crew led by celebrity reporter Lia, who are after the same story, but when they discover that the entire country has been overrun by zombies, what are the chances of them getting the message across? Unlike most zombie films, this actually tries to make a serious point - that if we don't feed the Third World, they'll come and feed on us!

Don't leave comments saying that I uploaded the wrong movie, because I didn't.
