Earth

The Earth is the homeworld of humanity and the center of human civilization. Disastrous climate change has rendered the Earth's shores fundamentally altered, with seas more than 200 feet above their level a century ago, an event known as the Inundation. The shift in the Earth's ecological balance was tied to a radical shift in political power within the Earth itself. Africa began the shift with the least to lose, and emerged with the least lost, while the industrialized world of North America and Europe fared the worst, many of their governments having broken up due to political sectarianism, ethnic nationalism, or regional economic rivalry. The Inundation was the final straw, and none of the traditional political powers such as the European Union, United States, Canada, Australia, or United Kingdom still exist in the 22nd century. While local governments still exist within these various areas, their inability to band together to deal with the crisis of the Inundation has resulted in hundreds of locally-focused political bodies along every line of political, religious, social, or economic thought. Not one of them has anything close to the power, resources, or will to project their ideology into space. Thus the world has passed to the vital powers, new and old, of Africa, Asia, and Latin America. Elsewhere, humans have colonized the last remaining stretches of virgin land upon the Earth, those beneath the seas, with extreme rivalry between the powers of the Atlantic and the Pacific.
