This is a very vital issue. It is unthinkable that in 50 years the world may hold about 1000 crores to 1200 crores people. The leaders of the world have the capacity and the means to reduce the world population by 500 crores in few weeks. Though it may sound cruel and inhuman to think about eliminating a large percentage of the population at a stroke.The truth is that the earth cannot sustain such a large population. A Large population will cause anarchy all over the world due to the shortage of food and other essentials. Society will be unstable. Elimination of 2/3 of the population may become the resort to continue the human race on the face of this butiful planet.
