I am thinking more along the lines of doing away with ignorance and stupidity. When every male is born, instead of circumcision (which is a brutal, archaic process) how about we install a valve in the seminal tubes. It would shut off the flow of semen needed for reproduction. When you want to have kids, you have to appeal to a team of psychiatrists, psychologists, and various other doctors to determine that you will raise a healthy, intelligent, open minded, logical, critical thinking individual. Then, they simply go in and open the valve. If you fail the tests, no kids for you. It would also reduce the overcrowding of the planet. Or, make a pill that makes seminal fluid taste like chocolate. Birth control solved.
