How does a healthy ocean contribute to life on this planet?


The ocean covers 71% of the planet, creates 70% of all oxygen, and sequesters carbon to mitigate climate change. The ocean is vital to life on earth.

Did you know?

More than 50% of the air we breathe is generated from phytoplankton in the ocean. Through the process of photosynthesis, these plankton convert carbon dioxide into oxygen that supports life on earth.

The ocean absorbs 20-30% of the world’s carbon dioxide, and has sequestered and contains 50 times more carbon than the atmosphere (UN Ocean Conference). This carbon is both suspended in ocean water, and sequestered in biomass at the bottom of the ocean.

Sustainable Development Goals: Life Under Water

If you didn’t guess already, the health of the ocean is directly related to a healthy planet. That’s why the ocean is a key element of the Sustainable Development Goals defined and agreed upon by the United Nations Member States and a bunch of other global organizations.

The Sustainable Development Goals (also referred to as the SDGs) are 17 goals that “provide a shared blueprint for peace and prosperity for people and the planet, now and into the future.”

Not surprisingly, one of those goals - SDG #14 - is focused on our ocean. “To conserve and sustainably use the oceans, seas, and marine resources for sustainable development.” The Ocean Heroes Network is proud to work with the United Nations and to support Ocean Heroes as you help us achieve this very important goal for a sustainable future and planet. 

Bottom line - a vibrant planet depends on a healthy ocean. That’s why we need Ocean Heroes like you to conserve and protect it.
