One certain effect of climate change is the accelerated extinction of plant and animal species.
As Wikipedia explains: "A species is extinct when the last existing member dies. Extinction therefore becomes a certainty when there are no surviving individuals that can reproduce and create a new generation. A species may become functionally extinct when only a handful of individuals survive, which cannot reproduce due to poor health, age, sparse distribution over a large range, a lack of individuals of both sexes (in sexually reproducing species), or other reasons."
Homo sapiens sapiens, aka humans, are animals, of course. Since more than 99% of all species that ever lived on Earth, amounting to over five billion species, have become extinct, it is reasonable to expect that humans will become extinct.
Still, many of us are troubled by the fact that humans are the cause of the current rapid climate change that has accelerated the extinction of plant and animal species creating a condition known as "mass extinction."
A 1998 survey of biologists conducted by New York's American Museum of Natural History supported the prediction that up to 20% of all living populations could become extinct within 20 years, seven years from now. It appears that prediction will be exceeded.
In a 2020 study Vertebrates on the brink as indicators of biological annihilation and the sixth mass extinction it was noted that a study of 29,400 species of terrestrial vertebrates found that the human-caused sixth mass extinction is likely accelerating, emphasizing the "extreme urgency of taking massive global actions to save humanity’s crucial life-support systems."
For those who may be interested, The Guardian, a non-profit British newspaper founded in 1821, has a grant-supported project - The Age of Extinction - focused on biodiversity highlighting the crisis represented by huge losses of animal, insect, bird and plant life around the world, exploring innovations attempting to slow these losses.
The Guardian is free (you may but need not donate). They do report on other news. In terms of its political orientation, it is left of center. And it is true that British, and American, and Chinese, and whatever national governments and private corporations have determined to delay significant action regarding climate change.
But now that Donald Trump is no longer President, perhaps more will find things like the problem of preventing the end of human life interesting.
This writer certainly recommends it as an alternative to Twitter, et al.
