What has happened with the ozone hole? / performance

Really – what happened?… Traveling through Romania last winter, I remembered my childhood holidays in 90s and the program of the „News” on polish TV. Every year in the beginning of summer, the ozone hole, aided by refrigerator pollution and aerosols, was launching a frontal attack with UV radiation causing skin cancer… so what is happening now? Does the ozone hole still exist and is only waiting to launch a conter-attack?
These thoughts were the inspiration for my performance.
