The whole world came to terms with the revelation of the conspiracy theory where aliens made a deal with the world governments. The aliens needed a consistent supply of food after a long voyage, with their scouts being deployed all over the world to make an agreement with the human authorities. According to the deal, when armada came to the earth the human governments would surrender all their livestock and billions of humans for their food supply and in exchange, the aliens would commit to leave the earth alone for another 5000 years as they go their way harvesting food from other planets. According to the governments that made this deal, it was a way of getting rid of low IQ people who were less productive and it was a way of protecting themselves and their families. As a result, most advanced nations installed systems to enable the aliens to recognize the proper human weight and size.
