The sea is a productive environment and offers far more opportunities than those currently being used. The sea has been studied far less than land, and it hides unknown potential. It is expected that in the next decades there will be targeted studies of the sea to find innovative solutions as to how it can be used. Blue bio-technology has much potential, including the use of biological resources from the sea for pharmaceuticals, food manufacturing, cleaning the environment, energy resources etc. There are also innovations relating to a combination of ways of using the sea, thus creating more intensive use of the sea in specific locations, while ensuring that large parts of the sea can largely be left alone.
