Oxygen

A natural disaster has struck us and brought humanity to the brink of extinction. Only a few survived because of the “Large Igneous Provinces”. These are volcanoes that do not explode, but instead, huge cracks open in the earth’s crust. From these cracks, bubbling lava flows across the landscape, releasing tons of toxic gases. The most dangerous thing about an igneous province is that it can take centuries to evaporate. These gases are carried by the wind across the world and change the composition of the atmosphere. One of these toxic igneous gases has reduced the oxygen levels in the air. Unfortunately, there is very little oxygen left in the world. Before it is too late for humanity, the Oxygen Center is invented. It produces oxygen through the electrolysis of underground water, and the necessary electricity is generated by using coal, but you must gradually switch from coal to sustainable energy sources. This is our only hope…
