The world’s oceans and coasts – the Blue World – are the cornucopia for humanity. They provide us with food, oxygen and livelihoods. Most of the world’s international trade travels by sea. Sea floors yield important minerals, sand and gravel. Technology is beginning to tap new sources of energy from ocean tides, waves and wind. Coastal habitats provide firewood, fibres and other resources, are natural carbon sinks and protect from storms and surges. Ocean views have been shown to improve people’s wellbeing and are an important reason homes near the sea have higher value. Tourism that relies on clean beaches, safe water and abundant marine wildlife provides many ocean communities with jobs, income and foreign exchange. Ocean recreation offers both market and non-market benefits to residents and visitors of the coasts.

Harmonizing traditional economic activity and ecosystem-dependent economic values is a challenge we must address, especially for our coasts and oceans. Persistent environmental pressures, including pollution, overharvesting of fisheries, and habitat conversion are driven by growing populations and the growing economic output these populations demand. These pressures have led to dramatic declines in the ecological state of our coasts and oceans. W...

World oceans, a cornucopia of goods and services World oceans, a cornucopia of goods and services

As much as 40 per cent of the world’s population now lives within 100 kilometres of the shoreline (Martínez, et al., 2007) and this population continues to grow – increasing our reliance and impact on the ocean and coast. Two thirds of the world’s megacities are on the coast.
