Prolong Human Being's Existence with Gao's Equation E = 7B2^44

The arable land of the Earth is about 4.4682 x 10^13 square meters. Based on Gao's equation E = 7B2^44, 982.28 square meters of arable land/person are the minimum for sustaining a comfortable life. From A. D. 2012 until around A. D. 2107 ~ 2147, there will appear the world first immigrant climax, people from countries such that India, China, African and the Middle East regions, where the population density is relatively high and/or economy is poor, will seek immigration to those countries, such as the United States, Germany, Canada, Australia and other European nations, where living standard is more affluent. The recent refugee tide is its prelude. There will appear other two immigration tides towards deserts/mountains and oceans before the doomsday to come around A. D. 3552 or much earlier. However, most of presidents, kings/queens, who are currently ruling many nations, are near-sighted and staying at patriotism or nationalism level only. They are not qualified to lead the future world. They need to be re-educated. To establish the "World Leaders Education Institut" is an urgent project to postpone doomsday.
