Ozone layer expected to finally be fully restored in 2066. The major problems at the global level are gradual with long-term thinking.

・UN Environment Program predicts that the ozone layer will return to 1980 levels by 2066

・The ozone layer protects the earth’s ecosystem by absorbing harmful ultraviolet rays from the sun.In the 1970s, it was discovered that ozone was being destroyed by chemicals such as chlorofluorocarbons (CFCs), and in the 1980s, an ozone hole was observed over Antarctica, where the ozone layer thinned and appeared as a hole.

・An assessment released at the end of 2018 confirmed an increase in the amount of CFCs (CFC-11) released from eastern China, which should have been totally eliminated.

・Subsequently regulated in China, global annual CFC emissions plummeted from more than 70 gigagrams per year to less than 50 gigagrams per year between 2018 and 2019

・If progress is made as planned, the ozone layer over the world, including Antarctica, is expected to recover to pre-1980 levels by 2066.

・They also pointed out that curbing emissions of CFCs and other substances is an effective means of combating global warming.

The bigger the problem, the more we need to take a long-term view and think about it.

 

We have been hearing about the depletion of the ozone layer since we were small children. Finally, the ozone layer is expected to be fully restored by 2066.

 

There are not many other examples of global-level crises being averted or recovered from.

 

When I think about it, I am somewhat deeply moved.

 

Humanity did not expect this (depletion of the ozone layer) when we were emitting large amounts of CFC gas around 1970.

It is possible that we, living in this day and age, are also creating a negative legacy without realizing it.

 

When I think about it, I am sometimes humbled.

There are still many problems at the global level, such as global warming and waste issues, but “plastics that break down” as described above are also being created.

 

I guess you could call this kind of thing a positive legacy.

 

So the negative and positive legacies of the current era will create a future. It is a repetition of this process.

 

Small problems can be solved quickly.

However, it still takes a long time to solve big problems at the global level.

 

With that as a premise, we have to take a long-term perspective.

We need to move on from the lessons we have learned and carefully consider our negative and positive legacies for the future.

 

I strongly felt that way when I read the article about the recovery of the ozone layer in 2066.(It’s been almost 100 years since 1970 when the problem occurred.)

 

Oh yeah, and a slight change of subject、

There have been a number of incidents involving young people that have been making the rounds recently. I thought the young people who made the mistakes were too shortsighted in their thinking.

 

I do not believe that all young people are short-sighted, but I do hope that the next generation will think long term and with depth in order to continue to solve major problems on a global level.

 

I’ll keep that in mind as well.

 

See you then.

 

2066. 43 years later, huh? It really takes a long time to solve and answer global-level problems, doesn’t it?
