Ticking time bombs- What risk do abandoned oil and gas wells pose?

The extraction of gas and oil poses a greater threat than previously thought. Leaks at disused drilling sites can trigger an environmental disaster at any time. If toxic substances escape, human lives are at risk. In many countries, oil and gas companies are legally obliged to seal abandoned wells immediately. However, the implementation and monitoring of these regulations is sporadic. Activists and whistleblowers are constantly trying to draw attention to this abuse.
