[2026] PTE Academic Reading - Multiple Choice, Single Answer

The exponential increase in satellite deployments over the past decade has precipitated a silent crisis in low Earth orbit, commonly referred to as the Kessler Syndrome. As defunct machinery, spent rocket stages, and fragmented particles accumulate, the probability of catastrophic orbital collisions rises dramatically. While commercial aerospace companies champion the deployment of mega-constellations as a means to democratize global internet access, they frequently downplay the long-term ecological consequences of a congested orbital environment. Current mitigation guidelines, which largely rely on voluntary compliance and end-of-life deorbiting protocols, have proven woefully inadequate in stemming the proliferation of space debris. Furthermore, the lack of a cohesive international regulatory framework allows corporations to prioritize rapid expansion over sustainable orbital practices. If the international community fails to transition from voluntary guidelines to enforceable, binding treaties, we risk rendering low Earth orbit entirely unusable for future scientific and telecommunication endeavors.
