The global mass extinction
I just came over an article about fertility problems in humans due to anthropogenic chemicals polluting the environment. A big problem indeed.
See here: https://www.scientificamerican.com/article/reproductive-problems-in-both-men-and-women-are-rising-at-an-alarming-rate/
The last lines of the article say: “In other words, we need to stop using each other and our unborn children as lab rats for EDC exposures. The health and the future of the human race really do depend on it.”
Stop the pollution, yes. But is the human species with 7.9 billion individuals threatened? No, not really. In this article, there was not a single word about the enormous ecological effects of this human-caused pollution. Not a word about how this affects other species, which are already struggling for survival of their very kind. Only a brief mention about climate change.
So I thought to put the human population status in perspective with some other (rather iconic) large mammals (source: IUCN red list):
Lion: 23.000- 39.000 decreasing
Cheetah: 6647 - decreasing
Chimpanzee: 172,700–299,700 – decreasing
Eastern gorilla: 2600 - decreasing
African wild dog: 1409 – decreasing
European bison: 2.518 - increasing
Human: 7.853.630.000 - increasing
By comparison – the world wide wild lion population barely fills one football stadium.
So no, it is not the fertility of the human species that I’m worried about, neither am I concerned about SARS-CoV-2, except that it comes from the horrible, bloody wildlife trade.
Life on Earth would breathe in relief if the human population gets down to a healthier size and stops confiscating everything on its path with its uncontrolled population growth and economic growth obsession. I also believe that a smaller human population size would benefit humans themselves and would increase wellbeing a lot more than the non-stop increase in pressure on limited resources and murderous competition over them. The figure below illustrates well how skewed the global mammalian biomass is with humans: 36%, livestock: 60% and wild mammals: 4%.
So, no I'm not concerned about humans reproducing a little less fast. I’m much more worried that humanity keeps pushing other animals to the limits of their ever dwindling living space, that threatened species are still shot as trophies, that non-human animals are still seen as tradable objects, that entire populations are still slaughtered because “there are too many” (how hypocrite is that, see the numbers) and that many people still deny other animals sentience and emotion, opening the door to objectification and terrible abuse (see the bioindustry).
I’m a also lot more concerned about the ecological effects of chemical waste, dramatic climate change, all this suffocating plastic waste and the wildfires scorching billions of animals, plants and fungi to death.
