In 2034, the earth heralded the eventual depletion of fossil fuels. Such a premature depletion was a profound shock to the human race. The human race and ecosystem had to face the challenge in the rapidly changing world by exploiting science, technology and alternative energy the human race had developed.
In 2046, the thus far accumulated global warming and, to make matters far worse, the abnormal activities of sunspots, dealt a deathblow to the human race’s alternative energy and food as well as the earth’s ecosystem.
Making full use of this tragedy, the Green Party further extended its sphere of influence and began to weigh on businesses and governments, putting under its control international environmental organizations including the United Nations Environment Program.
