Other species don’t build technology. Technology changes the carrying capacity. Humans also have environmental impact that varies far more than animals. A bird in Africa and a bird in America probably have similar environmental impact, but a person in Africa uses far fewer resources than a person in America.
Your position should be controversial because it is incorrect. The ecosystem dynamics of humans are nothing like that of other animals.
- forgetfreeman 3y agoYou're right. Birds haven't managed to cause a global mass extinction event. Meanwhile the technology you're touting has permitted our species to very nearly eradicate every marine fishery on the planet, fuck up CO2 levels badly enough to alter the climate globally, pump more water out of aquifers than can be recharged through natural processes, and has driven unrecoverable topsoil loss globally in all major agricultural areas. Your claim that carry capacity has been altered significantly doesn't mesh well with the facts on the ground. Available evidence suggests all we're really accomplishing is a temporary increase in humans on the planet in exchange for a bricked ecosystem. That ain't carry.

But we are the first of a long line of organisms that have the ability to do something about it, which is not nothing.
- forgetfreeman 3y agoRight, and the only non-hypothetical, physics-or-economics-defying solution we have available is to get our population down below some threshold where our existence on this planet becomes long-term sustainable.
- oivey 3y agoI’m not really sure what your comment has to do with carrying capacity. The damage humanity has done to the environment has more to do with a minority of the population using an insane number of resources.
- forgetfreeman 3y agoYou'd like to believe that and yet the only capital S sustainable human enclaves on the planet are indigenous populations with no industrial capacity.
- riversflow 3y agoIt's taught that the Green revolution was what broke Malthus, but so far we haven't solved the core problem(finite natural resources), only kicked the can down the road(we can turn crude oil into extra food). I hate to be so grim, but your position is, "technology has allowed humans to dominate the planet and push up our carry capacity. Externalities are building up as a result of those technologies and they make our enviroment less hospitable. We have yet figured out how to not do that, despite the problem being significantly more difficult now that we are locked in to supporting more people. But we will do it, for sure. " Is the last part saying that because their are have nots we are fine? You completely ignore the "we don't know how to make basic stuff at the quantities needed in a sustainable way" bit. I don't think banking on the discovery of new technology and having enough coordination as a species to implement that tech in a timely enough fashion is so safe that doubting it should be controversial.
