▪
This ozone layer is important to society and the environment for two reasons.
▪
But because of their longevity they are expected to go on damaging the ozone layer for decades.
level
▪
Thanks to wind drift, the highest ozone levels are often found in country areas.
▪
Each month during 1991 saw average ozone levels reach new highs.
▪
Government ministers admit that ozone levels are higher than anywhere else in the world.
loss
▪
Satellite observations reveal the area of major ozone loss to be about the size of the United States.
▪
If that rate of increase continues it is estimated that methyl bromide could account for one-sixth of ozone loss by 2000.
▪
During January, the scientists measured ozone losses of about one percent per day at some heights.
▪
Satellite measurements show that ozone loss worldwide has amounted to 2.9 percent over the past 10 years.
pollution
▪
In California, pines suffer from yellowish flecking due to ozone pollution and Los Angeles is notorious for its thick ozone smogs.
▪
A series of other steps will be triggered by particularly high levels of low-level ozone pollution .
▪
Given the enormous and costly pollution control efforts to tackle ozone pollution to date, these variable ten-year trends are very disappointing.
■ VERB
damage
▪
But because of their longevity they are expected to go on damaging the ozone layer for decades.
▪

▪
But they are thought to destroy the ozone layer, which protects the earth from the sun's rays.
▪
The polar regions are particularly at risk because the chemical reaction that destroys ozone is helped by their weather conditions.
