75,000 people, the last of the human race, in their radiation bunkers, finally realized that there is no radiation. Most of the people are in Russia and the USA. Some are still scattered around the world. The USA and the Russians are most likely the ones to survive, while the isolated pockets of humans would dwindle off, if they don't find any resources. The problem is, there is a lot of resources gone. Dead, floating fish would be their main source of food, and salt water would be their main source of water, if the technology to filter the salt and the bacteria out of the water. They do have that tech in Russia and the USA. Some countries, like the UK and China, do. The rest are most likely doomed to die. It is up to the humans to rebuild what has been destroyed, and populate the planet. Most of their knowledge is now gone, and they have to gain back the knowledge. Though, there is one weird thing. Where did the radiation go?
