It is a euphemism for population reduction. To “save the planet”.
I’ll tell you how to save the planet without killing 95% of the population – stop activities that destroy it! Like polluting the waterways, letting a plastic island build up in the middle of the pacific, clear felling old growth forests, not composting for soil regeneration but relying on artificial fertilizers and not regreening arid lands. I have seen videos that address these issues. The technology is available. We just need to focus on doing the things that work, not those that appear profitable in the short term but are long-term destructive.
Don’t buy into destructive solutions, no matter how creatively misnamed. Look beyond the labels to see the product created. Look instead for constructive solutions.
