The Marine and Coastal Access Act 2009 is a UK law designed to improve the management and protection of marine and coastal environments. It establishes a framework for sustainable development, ensuring that marine resources are used responsibly while preserving biodiversity. The Act also creates a system for marine planning, which helps balance the needs of various activities, such as fishing, shipping, and tourism. Additionally, the Act enhances public access to the coast by introducing the concept of a coastal path. This allows people to enjoy the natural beauty of the coastline while promoting recreational activities. The legislation aims to foster a better understanding of marine ecosystems and encourage community involvement in coastal management.
