World Oceans Day


8th June 2023


We celebrate today the World Oceans Day, which aims at highlighting the ocean and raising public awareness of its importance and the need to protect it.


An essential environment for the planet

We already detailed in our article “PIEZOLOGY – Underwater acoustics” the major issues of the marine environment and here are some key figures on the importance and potential of the Ocean:

  • The Ocean covers 70% of the planet.
  • The Ocean captures 30% of the CO2 emitted and provides 50% of the oxygen we breathe.
  • The Ocean represents 90% of the Earth’s natural habitat and contains tens of thousands of species.
  • Maritime transport accounts for more than 80% of world trade.
  • 40 million people could be employed by ocean industries by 2030.

A threatened environment to be protected from human activities

The marine environment has already been damaged by humans. 34% of fish stocks are overexploited, 20% of coral reefs have been destroyed without hope of improvement, and 70% are threatened.

The ocean is victim of pollution, especially plastic pollution. According to the Ellen MacArthur Foundation, the equivalent of a garbage truck is unloaded in the sea every minute. At this rate and if nothing changes, this number should increase to two per minute by 2030, and to four per minute by 2050. There would then be more plastic than fish in the ocean.

Chemicals and sewage also pollute the ocean. Reducing pollution of the oceans, therefore, involves reducing pollution altogether, because 80% of ocean pollution comes from land.


To drastically reduce the footprint of human activity on the ocean, efforts must be made at national and international levels:

  • Fight against overfishing and overexploitation,
  • Clean the oceans, especially of plastic waste,
  • Fight against climate change to reduce the rise in temperature, acidity and the level of seas and oceans,
  • Protect sensitive areas such as ocean depths,
  • Create new nature marine reserves and marine protected areas,
  • Fight against land pollution (fertilizer, phosphorus, pesticides, etc.),
  • Reduce urbanization and coastal development.

It is also possible to participate in the protection of the Ocean at the individual level by:

  • Reducing the use of single-use plastic (the most common waste found on European coasts),
  • Sustainably consuming seafood,
  • Using sunscreens that respect the ocean and corals,
  • Participating in waste collections and beach clean-ups,
  • Supporting organizations fighting for the protection of the ocean,
  • Informing and alerting on the importance and urgency of protecting the ocean.

Protecting the ocean also means ensuring the protection of habitats, biodiversity, the food chain and water quality. Managing the ocean more sustainably will therefore allow future generations to also benefit from its resources.


PYTHEAS Technology and the Ocean

The Ocean is a very important environment for PYTHEAS Technology because a large part of our activities is linked to it:

Our location on the shores of the Mediterranean Sea also reinforces our desire to protect and explore the marine environment.
