Original is from a Chinese propaganda series in the Deng era, 1983, I do not know the author of the edit.
“All the people plant trees, to regulate mountains and rivers”
Makes sense. Those would be messages for different audiences then.
“Red is green” = if you care about the environment, communism is the way
“Green is red” = if you’re a communist, environmentalism is praxis.
“Red is green” seems like the more important message though, since it’s aimed at pulling environmentally minded people to the left.
