2100, the overcrowded earth was going to evacuate up to ten long years for the terraforming of the earth’s environment. . .
The earth was filled with wastage of plastic, household waste, e-wast and fly ash. The pollution level was too high that people forced to use filtering masks all the time. Iron mines were going to empty. Coal, gases and petroleum had vanished before a decade, there was never-ending power requiring to run production in factories & lighting cities, seventy percentage power produced from nuclear reactors, in summer Para crossed fifty and less than freezing temperature in winter, almost all people forced to live artificial atmosphere. Jungle was no more, wild animals only found in zoo and lots of different species of birds had vanished where, no one could have explained. Unchecked dumping of sewage , domestic waste and industrial waste were killed most of rivers; polluted, toxic and unfit for any purpose. pH levels of water was more than eleven , DO level was almost Zero. Marine environment was also polluted a lot by interface of human , sea water near seashore looked black and smell disgust, so there was no beaches were in a condition to bath now.
The biggest problem of mankind was pure water, heavy construction of building and road had an negative impact on water level inside the soil, most of the water flooded to Ocean, lots of cities suffered by artificial flood in rainy season. Thousands of water purification plants were days and nights filtering water from Oceans and distributing it every cities of the world. Unproductive work were done by robots and software, so the unemployment was all time higher.
To balance the environment the United Nations made a plan, the plan was evacuation of the earth to terraforming it completely to convert the environment up to 14th century. Many opposed the idea first but all knew that there was no another option. A day was fixed and total population of the world shifted to some space habitat made by International Space agency. Only few officials, workers and robots were remaining behind to terraforming the earth.
But terraforming a planet was not an easy task. A bomb made by Russia was capable to make an super earthquake, it was used to destroy every manmade construction of the world, except seven wonder. Few machines were separated iron roads from concrete, thousands of machines worked to clean and purify the water of rivers. Enormous air purifiers took the whole responsibility to purify some highly polluted cities. Still Iron Fertilization method used to stimulate a phytoplankton boom in Ocean to increase the Oxygen level. Seven years needed to clean the earth. The next thing was again colonizes the earth. More than billions of trees were planted to make the earth in to a greenery planet again. Then mankind returned but now there was no permission to build a house in any continent. Waste free Cities were made already inside Oceans. Cities, nothing more than an enormous ship.
A new era started, which was known as the era of Oceans civilization in mankind History. . .
