My name is drax blofeld, and I am one of the most intelligent and wisest human beings born on this earth. In my infinite wisdom, I have determined that humanity has become too decadent and corrupt, and must be exterminated. I will repopulate the earth with people who I determine to be worthy, and all others do not deserve to live.
Using my cast resources, I have built a giant space station in space and have recruited the best and brightest to become citizens in this new world. We then developed a poison that is able to kill large numbers of people, but leave the beauty of the world intact. The poison takes the form of 70 canisters that were released into the atmosphere, each capable of killing 100 million people. With 7 billion people dead, the world is ready to be re-populated by my citizens. My heroic sacrifice has saved our species, but there is one thing we neglected to take into account:
What to do with all the corpses?
Billions of people decomposing all at once will certainly have harmful effects on the environment, as well as the health of my people. What is the best way to get rid of these bodies without harming my citizens? What other environmental problems would i need to take into consideration?
