Paragraph 2
Scientists in Canada did research on the
of rockets launched into space, and the
of people being hit by falling debris. There were 133 rocket
in 2021. That was a record. It looks like that
will be broken this year. The scientists said more than 60 per cent of rockets are abandoned in space after they release their
. The abandoned spacecraft can circle the
for years before they fall back down. A
finding of the research is that rocket parts are more
to hit somewhere (or someone) in the Global South. However, most rockets are launched from the Global North. The scientists say
and companies are "exporting risk to the
of the world".
