Well,in Japan, pollution(and in a larger sense, environmental issues) have become less of a concern, except when used as performance material by politicians. However, a major disaster broke out that slapped such peaceful Japanese people back and forth. Yes,the"East Japan Disaster" that struck the Tohoku region on March 11, 2011 and the ensuing "Fukushima Daiichi Nuclear Power Plant Meltdown". This forced residents living by the sea in Fukushima Prefecture to leave their homes. In my personal option,the tsunami may have been unpredictable, but a nuclear meltdown could clearly have been prevented.
This initial mistake caused immeasurable damage to agriculture and fisheries, and in the Reiwa era, the release of treated cooling water from the nuclear plant caused international outrage.
From a scientific point of view, there may be no problem as long as the radioactive material is well below the reference value. But doesn't that mean that we have learned nothing from the lessons of Minamata disease?
Perhaps this is not an appropriate analogy, but if you purified the treated water from a flush toilet to a level where fish could swim in it, would you still be able to drink it?
Sorry for going off-topic.
What I am trying to say is that pollution and environmental problems are no longer something that can be solved only by making things better in the countries concerned. Everyone wants to live a comfortable and clean life. It is no different in any countries and races. It is only arrogance to suppress them because it is inconvenient.
Then. what we can do is not to burden the current nature any further.To plant trees and let plants grow in the desert.To protect the marine ecosystem.
Shozo Tanaka left behind in his later years. "A true civilization is one that does not destroy mountains, rivers, and villages(where people live), and does not drive people to death." There has never been a time when these words could not have been more true.
