Isn't a black hole only able to emit Hawking radiation and not able to eject matter?

 

EDIT: I've just seen this comment, by the paper's lead author:

> What we think happened is this material was in an accretion disc surrounding the black hole after it was unbound. In 20% of cases you then see a radio outflow at the part where it’s torn apart, but in this case we have really good radio limits that this didn’t happen then (ie, didn’t see anything). Then after ~750 days for whatever reason this outflow began…

It's low, on both counts. But all environmental impacts from renewable tech is entirely irrelevant when one considers that the continued use of fossil fuels risks the collapse of modern civilisation.

Not at all. Tech has already been developed to fully recycle lithium and solar tech is being developed that won't use any toxic / rare materials. Though more importantly, unlike fossil fuels, renewable tech is not undermining the Earth's capacity to sustain life.
