Science has declared war upon a certain species of mosquito ( Aedes aegypti) believed to be responsible for most of the diseases associated with mosquitoes. Scientists have created a mutant strain that breeds with females of the Aedes aegypti strain and impregnates them with offspring that are sterile-thus within one generations that particular breed goes extinct. Testing in Brazil saw a reduction in the mosquito population by 90%!
Hmmm... I can't help but wonder if said technique might have human applications. The world cannot sustain another billion people and is vastly overpopulated.( Well, at least in third world areas- whites all over the world have a declining birthrate.) I leave it to your imagination as to what the world will be like if whites disappear and third world peoples dominate the planet.
