Drill down to discover the treasures beneath our feet that power our world. Fossil fuels–coal, oil, and natural gas–powered the industrial revolution and allowed us to build a way of life that many cherish today. Personal cars, planes, lights, hot showers–all of these are gifts from our fossil fuels… but they have a dirty dark side in that they are polluting the planet. What is it about these natural resources that have allowed them to fuel our civilization? What secrets are locked in their molecules? Where did that energy come from, and can we find alternative energy resources that come in a cleaner form? The hunt is on for new treasures that might allow us to power our modern way of life without damaging the environment. Join NOVA as we explore the resources that both power and pollute, from modern-day oil prospecting in California, to a mega-city utility company struggling to keep the lights on during hot summer days, to China where an engineer strives to solve one of the greatest obstacles to the success of solar power. Travel the globe to see how our energy treasures are changing—and if they can keep the lights on.

The disaster began during a routine systems test at reactor number four of the Chernobyl plant located near the town of Pripyat, on April 26, 1986. After a power surge, an emergency shutdown was attempted and after a subsequent power spike, there was a reactor vessel rupture and a series of steam explosions. The cascading course of events led to exposing the graphite moderator of the reactor to the air, causing it to catch fire. This sent a plume of highly radioactive fallout into the atmosphere. The fallout from Chernobyl prompted mass evacuations as it drifted over an extensive geographical area, including the western Soviet Union and Europe. Over 350,000 people were resettled from contaminated areas of Belarus, Russia, and the Ukraine. Thirty-one deaths are directly attributed to the accident, and all the deaths were among reactor staff and emergency workers. This is the kind of atmosphere Nelson and Ochota are investigating on Life After: Chernobyl as they attempt to determine how the radiation continues to impact the affected areas. They are allowed to stay for as long as they need to in order to conduct their ground-breaking research, but the duo must also be sure to take the necessary safety precautions. Broadway World noted in their Life After: Chernobyl article that by staying in the area for too long, the radiation exposure could reach dangerously high levels in their bodies, and they must always monitor the radiation levels.

The semantics of the model I'm working from use common goods/common property/ common pool resources (resources used by multiple people) and common property regimes (the institutions or social arrangements between people, the property rights regarding common pool resources).
