I guess they forgot about Fracking and Shale Oil.
The reason for sterilizing the human race is because supposedly we're running out of food and oil.
But with the Fracking and Shale Oil revolution, we don't have to worry about that anymore.
And I'm sure someone will solve the food problem as well. Heck, one documentary mentioned just using bugs to feed the world. They are high in protein, and you can just grind them into a powder then make a gel out of them.
Reminds me of the "Peak Oil" people claiming we've used half the oil on Earth, and it was all downhill from here. Then Fracking and Shale Oil came along to put that to rest. Technology always seems to save the day.
