To celebrate World Ocean Day, we are focusing on what businesses can do to protect marine ecosystems and sustain the blue economy. Human activity is destroying marine ecosystems at an unprecedented scale. As per WEF research, humans have altered over 60% of marine environments. On the other side, the blue economy is valued at €1.3 trillion and contributes to about 31 million direct full-time jobs. So, what more can business and sports organisations do to protect marine ecosystems and sustain the blue economy? In this article, Raffi Schieir, Co-Founder & Director of Bantam Materials supplying Prevented Ocean Plastic, sets out the business case for stopping plastics entering our ocean.
