Scientists recently estimated, for the first time, that the North Atlantic Ocean contains millions of tons of nanoplastics. To measure it, they used a detection method that picks up the chemical markers, or smell, of trace amounts of burned plastic. It's long been speculated that the oceans hold significant amounts of nanoplastics. but no one had managed to quantify them until now. by Shanna Hanbury #news #oceans #nanoplastics #climate #environment #plastic
Rupestrian grasslands form an ecosystem of extremes: covering a mere 0.8% of Brazil’s territory, they are home to 15% of the nation’s flora.

Conservation units to protect rupestrian grasslands have been set up, while universities are partnering with mining companies to drive restoration projects. by Letícia Klein #news #mining #ecosystems #environment #conservation
