In his latest documentary, “Population Boom,” filmmaker Werner Boote examines the topic of the overpopulation of the planet in an attempt to discover if in fact the exponential growth of the total number of human beings on Earth over the last several hundred years is something to be concerned about, or if it is just a cover for a different, more pressing problem.  Throughout the film, Boote travels to diverse locations all over the world, from Africa to Asia to North America, interviewing many local citizens about their opinions on the world population.
