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.

From chronic respiratory problems to cardiovascular diseases, diabetes and dementia, health damage caused by particulate matter air pollution is wide-ranging and serious. The World Health Organization (WHO) estimates that over six million deaths a year are caused by increased exposure to particulate matter.

Measurements taken with the new method reveal that 60% to 99% of oxygen radicals disappear within minutes or hours. Previous analyses of particulate matter based on filter deposition therefore delivered a distorted image.

The older methods of measuring involed collecting particles on a filter, that.filter is then collected days or weeks later, this suggest many of the particles (60%-99%) will be gone by then

Maybe this ahoukd even be cross posted to /c/fuckcars.
