The words
Have you ever worried about [debut / debris] from a falling rocket hitting you on the head? That scenario has never been high [in / on] the list of life's worries. The chances of a piece of space junk hitting [us / them] were almost zero. However, that [is / has] changing. Scientists say there is a [grown / growing] likelihood that rocket parts falling back to Earth could hit and kill someone [on / in] the next ten years. This is because more countries are [sending / seeding] more rockets into space. Scientists say space is becoming [congested / congestion] . They are calling on nations and companies that send rockets into space to [be / have] more responsible. They want them to control the reentry of any rocket parts floating in the [lowering / lower] atmosphere.

Scientists in Canada did research [on / at] the number of rockets launched into space, and the risk of people [being / been] hit by falling debris. There were 133 rocket launches in 2021. That was a [recording / record] . It looks like that record will be [broken / breaking] this year. The scientists said more than 60 per cent of rockets are [abandoned / abandon] in space after they release their satellites. The abandoned spacecraft can [square / circle] the earth for years before they fall back [up / down] . A [lock / key] finding of the research is that rocket parts are more likely to hit somewhere (or someone) in the Global South. However, most rockets are [lunched / launched] from the Global North. The scientists say countries and companies are "exporting risk to the [rests / rest] of the world".
