To suggest that overpopulation is controversial is itself absurd, as it is fundamental to the science of biology[1]. That a species can reach numbers where their environment and habitat is depleted or otherwise unlivable is fact, not controversy.
"Population Control" is certainly controversial, though, as it should be. And, though controversial, it should be considered seriously. Many environmentalists lose their credibility by speaking of "sustainability" on the one hand, but then disputing overpopulation on the other. We need to impact the earth much less, and keeping our numbers down is a very effective way of doing so. That, plus using energy and resources more cleanly and efficiently.
