Space exploration has led to concerns about space debris, which poses a significant threat to both operational satellites and future missions. The accumulation of defunct satellites, spent rocket stages, and other debris increases the risk of collisions, potentially creating more debris in a cascading effect. Additionally, the environmental impact of rocket launches, including greenhouse gas emissions and ozone layer depletion, raises questions about the sustainability of increased space activities. Lastly, the prioritization of resources for space missions can divert funding away from pressing issues on Earth, such as poverty and climate change.
