Oceans, coastlines and coastal communities are being disproportionately impacted by increasing ocean pollution, increasing temperatures and rising sea levels. Ocean currents are changing, certain oxygen zones are being depleted and some marine species are being depleted. Furthermore, polar ice caps are melting causing rising sea levels with significant impacts on shorelines. A wide range of technologies already exist and are being developed to protect the oceans and its communities. These range from robots which collect beach pollution, sensors which detect ocean temperatures and underwater drones that collect data on marine life. Sustainable fisheries are also also wide spread. They help protect vulnerable marine life, increase food security and enhance the well-being of fishing communities. Coastal zones are being protected through wetland restoration, beach nourishment and a combination of other well-established and innovative technologies.
