I know the answer to this problem probably lies with pollution - such as chemicals, pesticides and plastics in the food supply --- however to keep the conversation lively I submit the following idea.
In the following NDE (Near Death Experience) this lawyer from Canada reported being shown Blue Beings here on Earth who are actively working here on Earth. They are hidden in the worlds universities using advanced technologies to makes themselves look human. They are very interested in reducing the " Aggression" rate of humans here on Earth. But one of the good ways to reduce Male Aggression is to lower "Testosterone" . Testosterone is a male hormone (actually it is even found in women) that when reduced drastically affects sperm- fertility rates, depression and so on.
You can see this following this link to the first posting
example of what you can see and read
*** ***QUESTION----What are aliens studying about Humans -- Likely the answer is found in the planet visited where a plant was found that lowers male human aggression and boys are chemically castrated (as a warning to us now). -- Testosterone levels have dropped 50% in males apparently since the 1950s here on Earth .
The female Alien revealed "working at Oxford" was wearing a silver jump suit and had a projector device implanted in her chest.
*****--Opinion-- Alien is a bio-mechanical being- the suit is part of a projector screen -the device in the chest is the computer and power source. The only way she could ever be detected would be if someone laid his hand on her and they would see their own hand disappear a little under the projected image of a human.
******OPINION-----Likely---The Alien is manipulating other humans to push them into scientific areas ie study of lowering testosterone or other scientific areas - following the role of soon to arrive Hybrids which will take over the control of humans. (VERY GOOD IDEA TO REMOTE VIEW) Except we may be remote viewing our demise here on Earth-- This race is probably one of the Hybrid creators soon to arrive- which we will not detect and probably they are all here now in positions here on earth. (hence that is why we are being told of this blue being-- THE CARD GAME IS OVER WE ARE BEING TOLD-- GIVE UP-- OR ELSE !! )
+++++Blue being admits she is here studying how to "suppress" negative human emotions. Later Lawyer is taken to a planet where Negative emotions in Humans in another world is shown to be very effective through chemical castration. Question do we here on Earth Chemically castrate other humans ?? Yes we do. Violent rapists' have been chemically castrated ordered to take substances to reduce their sex drive.
++++Blue alien says their are many others like her working right here on earth within medical fields to find a way to suppress these human emotions
