Definitely revealing the real game the "green" movements have been playing in service of the Союз Советских Социалистических Республик.
Keep in mind that even with an ever-expanding pie, strife over "fair share" has been a constant feature of the post-WWII era as well as the first quarter of the 21st century. Nothing good can come out of actions that purposefully destroy the pie.
It's folly to think destroying the environment won't impact this pie. Whether this is a "game" or not that the green movements have been playing, does not mean the article isn't true.
Besides, the pie size only matters on a per-capita basis, and most advanced economies have below-replacement fertility, meaning their economies can shrink without reducing living standards, even if they do nothing else differently. Barring population addition via immigration.
Having grown up in an actually polluted city where we had to keep ammonia in a container in the living room to scrub CO during winter months, "destroying the environment" by breathing thing is a little overwrought.
Also, reducing the future potential of productive new individuals from joining society is not the utopia you think it is.
