How are coasts harmed by people?

Coasts are harmed by people through pollution, such as plastic waste and chemicals from industries that contaminate marine ecosystems. Coastal development, including urbanization and tourism, leads to habitat destruction and increased erosion. Additionally, activities like overfishing and boat traffic disrupt marine life and contribute to biodiversity loss. Climate change, driven by human actions, exacerbates these issues through rising sea levels and increased storm intensity.
