Zika seems like a trial run for what I believe the Globalists will attempt.
They want a severe population decrease, especially now that Robotics and AI are almost within grasp.
They have seen that reducing population by killing the living works out poorly — for them.
I believe they will engineer a conception problem. People will have a great deal of trouble creating children.
Remember, too, many of the GMO tests are showing rats to be infertile and long term sterility.
