Rocket launches are reportedly having a significant environmental impact, with some outlets suggesting they are altering the upper atmosphere and potentially threatening the ozone layer. The growing number of launches is said to be causing rapid accumulation of pollution in the upper atmosphere, although the extent and consequences of this impact are not entirely clear. Some reports also touch on the idea that satellite launches could be having unintended effects on the earth's climate, but the focus of these concerns is not universally agreed upon.
