Stretching out over more than two thirds of the Earth, the high seas remain a relatively vast, complex and partially uncharted marine environment It is usually described in terms of a vast, barren space in the geography of the world, but in fact it is much more interesting. We are dealing with high seas, the vast and rich ecosystem that is home to a tremendous variety of sea life, which is so important for the existence of our planet.

It is important to note that these complex systems play a vital role in the climate control on Earth; through photosynthesis, phytoplankton contributes to the generation of half the oxygen we breathe. Also, the ocean has a large area of coverage and takes a large amount of CO2, an important greenhouse gas, resulting in mitigation of climate change.

Apart from their conservation importance the high seas are also an important source of resources. Fisheries feed millions, fish as a source of protein is consumed globally by approximately 3 billion people. The seabed may contain affluent mineral resources including nodules that are valuable for their metal content such as cobalt and manganese which are useful in the current industries and technology.

High sea is also the lifeline of international trade, and several vessels sail in these areas daily transporting all forms of products including food products, manufactured goods and energy products. For this reason, the daily traffic of maritime vessels highlights the need for free navigation in the seas. 

Last but not the least; the high seas have a major role in scientific research.
