Monobiodiversity

In the near future, scientists have discovered a way to genetically modify people at the push of the button. UNA stands for Uberribonucleic Acid. It gives normal humans superhuman abilities. Even a millionth of your DNA being converted into UNA can result in multiple levels of power that no natural thing can bring.

But when some drunk scientists forgot to seal a test tube, UNA leaked out into the Amazon Rainforest, making all of South America uninhabitable within two days.

Twenty years later, the only safe place are the isolated islands of Micronesia. Multiple people have attempted to explore the world, only one coming back. That person reported giant spiders and snakes with ten times more potent venom crawling around Australia. If all the world's a stage, then we are merely the sacrificial actors.
