The worlds biggest problem is population growth. All that goes in bad way crime, corruption, assassination, robbery, murders everything is at increasing rate in world. And basic reason for all this is population growth. Everyone trying to follow simple rule of life
Survival of the Fittest
Result is: Population increase-> everyone trying to be fittest-> doing crimes to prove/survive that. So my question is is there any way to stop birth rate completely. (I am looking for a solution/possibilities in future to find a solution for this... like lets say we have a gas/chemical which if came in air will spread everywhere and all humans will become weaken that they can not commit any crime and also it will make them sterile so no further generation possible).
