Science Fiction is awash in stories whereby time travelers from the future travel to the past to prevent some catastrophe that has impacted negatively upon their future. The reality is that if we do not change the timeline we are on at the present the entire white race goes extinct sometime in the mid or late 22nd century via negative birthrates and assimilation. What will means is that China (AKA East Asians) will become the dominant race on the planet and we can expect an invasion of the former majority white regions of the world and quite possibly the ethnic cleansing of the racially mixed and non-Chinese people that now reside in these areas. If that be the case then the great experiment in multiracial diversity the West has undertaken ends in genocide by the Greater Chinese Co-Prosperity Sphere! In which case the entire planet becomes the exclusive domain of the new Chinese master race. This is not so far fetched when we consider most Political Scientists and Historians predict China will surpass the United States in the decades to come in terms of economy and eventually become a super-power that will displace the United States. Even now China has enacted a colonial policy in Africa building their infrastructure and technology in exchange for them signing their mineral rights away. I need not remind you that China has also scrapped its one child policy. All that excess population will have to go somewhere!
