Aerospace industry's metal particles may harm the planet

Satellites and spacecraft are leaving metal particles in the stratosphere, raising concerns about potential harm to the planet. About 10% of stratospheric particles now come from the aerospace industry. These particles could seed polar stratospheric clouds, potentially damaging the ozone layer. With the space industry rapidly growing, scientists are eager to understand the implications. Aerospace debris could make up 50% of stratospheric particles within a few decades. This raises the urgency to comprehend their impact.
