Affirmative.
The global population has grown from 1 billion in 1800 to 8.1 billion in 2024. Unfortunately most economic models are based on a constantly expanding population. There is (that we know of) this one small planet suitable for our life form. If the human race destroys it by breeding like rabbits then there no place else to move to. Captain Kirk is not going to come along and bail us out.
This is an old ideology that stretches back to Thomas Malthus and is responsible, variously, for the Irish famine, the late 19th century Indian famines reponsible for 10s of millions of deaths, and arguably the death toll of WW1 (whose primary function was really to massacre the unemployed population of Europe in a failed attempt to forestall the end of the aristocratic age), and God knows what else. Liberals who endorse it are essentially in bed with eugenicists like Peter Thiel and Bill Gates, but the Fabians had more or less the same position so this kind of ideological unity among liberals and fascists is nothing new.
It's not surprising this shared outlook exists because it's based on a common anthropology, namely that human beings are merely self-interested animals who as you say "breed like rabbits". The truth is that this anthropology of selfishness is historically specific, it's produced by the pressures of class society. Whether in slave societies like the Roman Empire, or capitalist societies where money regulates all social life, to
not be self-interested is tantamount to suicide, so it's no surprise that extreme consumption, waste and thoughtlessness dominate. This isn't a "natural" state of affairs but one maintained at great cost and brutality by the class that reaps its economic fruits, the normative state of humanity is one of shared interest and the fragments of this are everywhere to see (and always being renewed). We're not mechanically doomed to the Malthusian catastrophe, past and existing societies show that it's possible to live in balance with nature (even in very large complex social formations) and extremely basic things like not flooding the earth and water with all kinds of frocking poison can be rationally managed. The current world does have its own mechanical impetus though, the frequent comparison to a cancer is totally apt.
The other reason the Malthusian hypothesis is wrong is that, as even von Braun said, nothing is created and nothing is destroyed; life begets life, the jungle isn't on the verge of depleting the environment even though it's teeming with life, the problem with human societies is that they're full of metabolic rifts, i.e. imbalances in the reproduction of life cycles. It's totally possible to sustain existing humanity and its future, though not solely through technological innovations since self-interest is perpetuated by class society hence a political solution is the precondition. I mentioned this in another thread but liquid thorium nuclear reactors, which are currently being built en masse by China, are basically 100% safe (since any leak in containment results in killing the chain reaction, look it up) and forms almost a perfectly closed cycle with minute quantities of waste relative to older nuclear technologies. The kicker is that thorium reactors were invented in the 1960s by the American government at the Oak Hill Laboratories, but axed for "technical problems" - i.e. the prospect of almost limitless, safe energy would have upended the established order built on scarcity. The Chinese government has no such qualms because its overriding interest right now is national economic development and since it doesn't occupy the hegemonic position in the world system (as the U.S. does) it doesn't particularly care about upending things a little.
Concerning global warming, it's almost certainly some kind of problem, but as Jason W. Moore says there isn't just one ecological crisis but a whole multitude of them. Like eventually it'll be a problem (and already is for many people) but the reason for the mass extinction event currently happening in the oceans, the insect world, and the incredible rise in cancers and disabilities generation-upon-generation (carefully concealed by the "War on Cancer" in mortality statistics, although even this is starting to fail), is probably due more to the omnipresence of pollutants (e.g. heavy metals, glyphosates, dioxins, plastics, PFAS, PCBs and only God knows what else since we're pumping out more of them every year with no real oversight) than the water being a few degrees warmer. I think a lot of the resistance to the global warming narrative (which I believe is evidently true) exists because it's also evidently true that the current rulers absolutely don't care about global warming and are only using it as a scare tactic to push through their desired political changes (which are ironically devised with the coming political upheavals over environmental crises in mind).
