Such or similar false apocalyptic claims have been made frequently for the past 50 years or so!
Human ingenuity has already defeated many of those and other apocalyptic claims in the past!
Look at the chart below, this is primitive trend extrapolation. Yes, the growth of human population since about 1800 AD was extreme and a miracle, but it will not continue like this!
This is superstition, not science! Alarmism and hysteria! Perhaps very lucrative for these pseudo scientists behind this study!
When scientists call for authoritarian central government watch out!
I am not sure why any journal today would publish such rubbish again!
Actually, world population may even decrease over the next several decades. The population of e.g. China and Japan is already shrinking. E.g. Germany's German population may also be shrinking. I bet also India's population growth is already slowing and so on.
"Earth has already exceeded its ability to support the global population sustainably, with new research warning of increasing pressure on food security, climate stability, and human well-being. However, slowing population growth and raising global awareness could still offer humanity some hope. ..."
From the abstract:
"The ecological concept of human carrying capacity is necessarily complicated because human beings are the ‘ultimate ecosystem engineers’ who moderate the environment for their benefit.
For at least the last few hundred years, human ingenuity, access to massive stocks of fossil fuels, and technological development have driven facilitation whereby increasing human abundance has promoted higher population growth rates.
However, this positive relationship broke down during the 1950s, and by 1962, the global human population entered a phase where the growth rate consistently declined as population increased.
The onset of this negative phase occurred 8 years before a global biocapacity deficit began in 1970. The onset of the negative phase also varies regionally, with the lowest-income and highest fertility regions entering this phase later than higher-income regions.
A Ricker logistic model fitted to the negative phase predicts that the global population could reach 11.7–12.4 billion people between 2067 and 2076. The same model fitted to the facilitation phase predicts a maximum population of 2.5 billion people that Earth might be able to maintain [???].
The negative phase also correlates strongly with the trend in global temperature anomaly, ecological footprint, and total emissions, with more of their variation explained by increasing population size rather than increasing per-capita consumption.
The Earth cannot sustain the future human population, or even today’s, without a major overhaul of socio-cultural practices [???] for using land, water, energy, biodiversity, and other resources."
Global human population has surpassed Earth's sustainable carrying capacity
