According to a research from last year

Sixty-six percent of the entire planet is deep ocean (≥200 m), and our data show that we have visually observed less than 0.001%, a total area approximately a tenth of the size of Belgium.

If we have seen so little of the deep sea, let alone study it, I am pretty sure scientists cannot really make assessments of the impact of deep-sea mining.

the body cameras are definitely a good thing

I am not so sure about that tbh. Where I live (another continent) they are used by some sort of officers to patrol boarders. Whenever these officers do push-backs/kill immigrants/etc their cameras are never on.

Th following article is more relevant to the US

The history of police body cameras is more complex and troubling than we’ve been told

With body cameras, law enforcement agencies could expand their surveillance capacity, mitigate police brutality lawsuits, create “highly controllable evidence” against the largely poor, largely Black citizens of whom police often seek to capture footage, and quell social unrest by creating “comprehensive digital archives” of attendees at protests for social change.
