The increase in space travel and rocket launches poses a potential threat to the ozone layer. Rocket engines emit gases and particles that can cause damage to the ozone layer, which protects the Earth from harmful ultraviolet radiation. While the current impact of rocket launches on the ozone layer is relatively small, projected growth in space travel could lead to a more significant threat. The emissions from rocket launches, including ozone-depleting substances, have the potential to harm the protective ozone layer, which could have serious consequences for human health and the environment[1][2][3][4][5]. Therefore, it is important to carefully consider and monitor the environmental impact of increased space travel and rocket launches to protect the ozone layer and the planet.
