Welsh seas are an important part of Welsh heritage and culture, and are entwined in Welsh history particularly through fishing traditions, ports, and the industries that they have supported. A wealth of archaeological sites and remains can still be seen today. Today, the Welsh marine environment still plays a fundamental role in the Welsh economy; with over 60% of the population of Wales living and working around the coast, and coastal tourism contributing more than £602 million in 2013 to the Welsh economy (this figure excludes multiplier effects).
Welsh seas support thousands of jobs across a range of sectors and provide us with many of the resources we use daily. We rely heavily on the sea to provide us with food, to regulate our climate, and to provide transport. Increasingly, we are looking to the sea as a source of renewable energy. We also enjoy water-based recreation such as angling, sailing, and diving. It is clear that our coasts and seas provide us with extensive benefits and enhance our quality of life – they must be protected and sustainably managed to ensure that we can continue to enjoy and benefit from them today and in the future.
