Growing up in The Bahamas, Kristal Ambrose developed a close relationship with the ocean. Swimming regularly with her father helped foster her affection for marine life. She has described her childhood as a happy, family-centered upbringing, surrounded by her parents, sister, grandparents, and friends. Education was strongly encouraged at home, while weekends spent with her grandparents and visits to the beach deepened her connection to her island environment.
Ambrose, also known as “Kristal Ocean,” is a Bahamian marine scientist and environmental campaigner whose work focuses on plastic pollution. As The Bahamas is one of the Commonwealth’s 56 independent member countries, her work is linked to a wider family of island nations.
A turning point came after she completed high school and began working at a Bahamian aquarium. There, she spent two days helping remove plastic from a sea turtle suffering from an internal blockage. The experience deeply affected her, strengthening her determination to reduce the waste entering the ocean. In 2012, at age 22, she joined a sailing expedition across the Pacific to study the Western Garbage Patch, an area containing massive amounts of floating marine debris. Seeing familiar household objects among the rubbish made her recognize how everyday consumption contributes to a global problem.
Rather than treating the experience as a distant environmental issue, Ambrose returned home determined to involve her own community. In 2013, she established the Bahamas Plastic Movement, a non-profit organization that combines research, education, citizen science, and advocacy. Its aim is to help Bahamians understand plastic pollution and take part in developing solutions. One of its central priorities has been engaging young people, giving them opportunities to investigate local beaches, collect information, and learn how waste travels from land into the sea.
Her education supported this work. Ambrose first earned an associate degree in fisheries management and aquaculture from Hocking College. She then graduated from Gannon University with a bachelor’s degree in interdisciplinary studies, concentrating on environmental science, biology, and education. At Dalhousie University in Canada, she completed a master’s degree in marine affairs, focusing on marine debris and plastic pollution. She later earned a PhD in maritime affairs from the World Maritime University in 2023, further developing her research into marine debris and the challenges facing Caribbean island states.
Ambrose’s campaign also moved beyond education into national policy. Working with young people involved in the Bahamas Plastic Movement, she helped persuade the government to take stronger action against disposable plastic products. The government announced a ban in 2018 covering single-use plastic bags, cutlery, straws, and Styrofoam food containers and cups. The restrictions came into effect in January 2020. The Goldman Environmental Prize recognized her contribution that year, naming her the winner for Islands and Island Nations. It was the first time a person from The Bahamas received the award.
Her work has continued to show that environmental action does not have to begin with a large institution or a powerful position. It can start with a personal experience, grow through scientific learning, and become more effective when a community is included. Through youth programs and public education, Ambrose has encouraged a new generation of Bahamians to see themselves as protectors of their marine environment.
As a woman from a small Commonwealth island nation, her achievements also bring attention to the role Caribbean communities can play in international environmental discussions. Plastic waste crosses borders through ocean currents, so solutions require cooperation as well as local responsibility. Ambrose’s journey—which began as a beach-loving child and led to her becoming a scientist and organizer whose campaign helped change national policy—clearly demonstrates how knowledge, persistence, and community involvement can turn concern into lasting action.
