Misleading, because satellites are made of different materials to meteors. Satellites are the dominant injection source of 24 elements into the atmosphere, including Al, Cu, Ti, Nb, Co, Zn, Sn, Pb, Ag, Li, V, Hf, W, Ge, Mo, Zr, B, and Ba. This list includes many transition metals, whose catalytic effects on ozone and cloud nucleation are mostly unknown.
Copper in particular is a well-known catalyst for the destruction of ozone.

- aruggirello 4mo agoSorry, you're right. My assumption was that, given meteorites are metal rich, and two orders of magnitude more mass, the human contribution was negligible. It turns out I was wrong.
