When I say "GMO", I mean laboratory manipulation of genetics, not selective breeding. The tech was first done experimentally in the 1970s, and didn't become commercially viable at all until the 1990s, and it wasn't until quite recently that it became easy and inexpensive. Most of the 20th century population explosion happened before that, and the expected rate of population growth over the next century is an order of magnitude lower than the previous century.
