Another way electric cars clean the air: study says brake dust reduced by 83% (electrek.co)
A new study is out which quantifies just how much EVs help not just in cutting harmful exhaust emissions, but also cutting other types of pollution that come from personal vehicles. But of course, public transport, biking and walking are even better.

One-sixth of the planet's cropland has toxic levels of one or more metals (elpais.com)
The first 30 centimeters of soil are the foundation of life. This foot-deep slice of the pedosphere is the vital space for most plant roots. When roots go deeper, it’s to anchor the plant, not to nourish it. Within this narrow band, bacteria, fungi, nematodes, and countless other microscopic organisms form the so-called biological crust, which in turn supports the larger life forms above.

Age of Invention: How Coal Won (ageofinvention.xyz)
Over the course of 1570-1600, people all along the eastern coast of England, and especially in the rapidly-expanding city of London, stopped using wood to heat their homes. They instead began to burn an especially crumbly, sulphurous coal from near Newcastle in Northumberland — a fuel whose thick, heavy smoke reeked, stinging their eyes, making them wheeze and cough, and tarnishing their clothes, furnishings, and skin.
