When mankind started inputting the events into Earth's biosphere it was unable to handle, the biosphere crashed. Genetically modified organisms led to the death of all life forms except androids produced for the last war. They collected resources, built robots, sent them out to fight, and so on. The Earth made a replacement for the biosphere based on radiation energy rather than solar energy. The androids have discovered that the radiation storms leave a trail of nuclear material and have started collecting it for use as an energy source. And they've started to evolve. Collecting the metal debris, they've analyzed and redesigned the robots, advancing their evolution. Because of this situation, planetary review panel has asked the design council to stop the demolition of planet surface and reallocation to design pool. And design council has accepted the recommendation with one condition. A clearly dominant android form must emerge before the next review, or the planet will be reassigned to design pool.
