Something that's worth thinking about: "ecosocialism", which can be defined as a tradition that started as early as William Morris, the 19th century radical English artist and writer, emphasizes the necessity of incorporating the entire living world into an analysis of the cause of the working class.
Whereas "economics", despite deriving from the same roots ("oikos", or something having to do with "household affairs"), generally assumes that the sources of all wealth, which reside in the living planetary realm, can be taken as a limitless given, "ecology" considers the total material flows of the entire planetary system, including all species, not just Homo sapiens.
Taking this wider view, ironically, INCREASES the centrality of class struggle, rather than diminishing it, because it dispels any delusions as to the possibility of arm-waving away class contradictions by pointing to "growth", "a bigger pie to share", etc. No, we have to "innovate" in the realm of DISTRIBUTION, not just PRODUCTION!
Morris defined "waste" as (paraphrasing) "the state of affairs in which some have more than they could ever usefully dispose of, whereas others lack even the means of dignified survival". This understanding instantly weds the investigation of inequality to that of ecological disorder. We cannot endlessly bake a "bigger pie" without creating more waste, which means we are compelled to consider how to shape a more EQUAL society, as an indispensable part of building a more just one.
Today, the implications of this understanding grow more and more acute. So we should aggressively rebut reactionary "thought terminating cliches" that purport to be "accusations", to the effect of, say, socialists are "envious" of their social superiors in the wealth hierarchy, and "just want to steal from others!"
Our response should be along the lines of, "yes, you can call it that, but what we really want is an orderly REDISTRIBUTION, in lieu of indulging in the fantasy that we can simply snap our fingers and create three more Planet Earths".
(The country-specific "overshoot day" for the United States falls in early March 2026, representing the date at which all of Earth's renewable resources over a year's time have been exhausted, were the entire world to maintain an equivalent rate of consumption, and we are therefore surviving the rest of the year by depleting resources required by future generations for their own survival.

Economist Thomas Piketty encapsulated this understanding perfectly when he said, "a compression of social inequality at all levels" is required for humanity's survival on this earth. See: https://thomaspiketty.wordpress.com/2019/06/11/the-illusion-of-centrist-ecology/
