This is the place for discussing the potential collapse of modern civilization and the environment.

Collapse, in this context, refers to the significant loss of an established level or complexity towards a much simpler state. It can occur differently within many areas, orderly or chaotically, and be willing or unwilling. It does not necessarily imply human extinction or a singular, global event. Although, the longer the duration, the more it resembles a ‘decline’ instead of collapse.

Air pollution (PM2.5) can be a direct vector of antibiotic resistant bacteria, and caused approx 0.5M deaths in 2018, per new study.

Just published in The Lancet Planetary Health (peer-reviewed scientific journal):
"Association between particulate matter (PM)2·5 air pollution and clinical antibiotic resistance: a global analysis" (by Zhenchao Zhou, PhD, Xinyi Shuai, BSc, et al.)
https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(23)00135-3/fulltext

"The major air pollutant, in the form of particulate matter (PM)2.5, has been shown to contain diverse antibiotic-resistant bacteria and antibiotic-resistance genes, which are transferred between environments and directly inhaled by humans, causing respiratory-tract injury and infection. [7, 8, 9] PM2.5 could also increase cell-membrane permeability to enhance the efficiency of horizontal gene transfer, accelerating the evolution and exchange of antibiotic-resistance elements in bacterial pathogens. [10, 11]"

"Findings

The final dataset included more than 11.5 million tested isolates. Raw antibiotic-resistance data included nine pathogens and 43 types of antibiotic agents. Significant correlations between PM2.5 and antibiotic resistance were consistent globally in most antibiotic-resistant bacteria (R^2=0.42–0.76, p<0.0001), and correlations have strengthened over time. Antibiotic resistance derived from PM2.5 caused an estimated 0.48 (95% CI 0.34–0.60) million premature deaths and 18.2 (13.4–23.0) million years of life lost in 2018 worldwide, corresponding to an annual welfare loss of US$395 (290–500) billion due to premature deaths."
