I grew up in Wolverhampton in the 70s and 80s. The area lost a lot of heavy industry. There was an area near us that was wasteland with a large number of derelict factories and buildings. It was like a deadly adventure playground. We'd always be there riding bikes down asbestos hills or fighting the Germans around the factories.
In the 00s the area was redeveloped. It was quite costly to do because of the large amount of asbestos and other toxic materials in the area.
But there was one bit that they still haven't touched to this day. Apparently when the infectious disease hospital closed the NHS decided to bury medical waste there. This included radioactive waste from an xray machine destroyed by fire. Over time they lost the records showing exactly what was buried where.
Despite all of this, I don't have a single superpower.
