Even though countries took action to stop ozone depletion many years ago, ozone levels still won't be back to "normal" for:
A. several more years
B. several thousand years
C. several decades
D. several hundred years

Asked by Eav11

Answer (2)

Ozone levels are expected to take several decades to return to normal after significant international action was taken to reduce substances that deplete it. The Montreal Protocol, established in 1987, has led to a substantial decrease in these harmful chemicals, but recovery will take time due to their long-lasting effects. Therefore, the correct answer is C. several decades.

Countries have taken action to stop ozone depletion, but ozone levels won't return to normal for several decades. The recovery time varies based on atmospheric conditions and the persistence of CFCs. Complete stabilization is expected within that timeframe. ;
