The significance of studying human impact on coastlines lies in understanding the effects of urban development, pollution, and climate change on marine and coastal ecosystems. Anthropogenic activities have led to habitat degradation, loss of biodiversity, and increased vulnerability to natural disasters such as storm surges and erosion. By analyzing these impacts, strategies can be formulated to protect and restore coastal environments, enhancing resilience and ensuring the sustainable use of coastal resources while safeguarding human interests and ecosystems.
