Today is World Oceans Day! The ocean covers more than 70% of the Earth’s surface and produces half the world’s oxygen. Yet human threats like plastic pollution are destroying it. Let’s work together to end the ocean plastic crisis.
World Oceans Day seeks to raise awareness regarding the interconnectedness of Earth’s vast water bodies, the role they play in supporting multiple ecosystems, and the myriad benefits they offer to humankind. Drawing attention to current challenges, such as marine pollution and climate change, the observance seeks to inspire collective stewardship of this invaluable shared resource. The day serves as an opportunity for nations to collaborate, spreading knowledge and encouraging action towards the conservation and sustainable use of the world's oceans, their coastlines, and marine life.
The roots of World Oceans Day can be traced back to the 1992 Earth Summit in Rio de Janeiro, where numerous countries, including Canada, acknowledged their shared responsibilities towards ocean conservation. In 2008, the United Nations officially designated June 8 as World Oceans Day. Canada has a vested interest in these efforts, as it possesses the longest coastline in the world, stretching over 202,080 kilometers, and boasts numerous marine ecosystems teeming with biodiversity. Given the environmental, economic, and cultural importance of these waters, Canadians are in a prime position to effect lasting positive change through their contributions to this global movement.
Each year on June 8, Canadians from coast to coast participate in a variety of activities to honour and protect the oceans. These may include local beach clean-ups, educational workshops, sustainable seafood events, and marine conservation-focused presentations. Through these initiatives, citizens of all ages engage in conversations about ocean health, learn about the unique marine life that inhabits Canadian waters, and gain a deeper understanding of the actions they can take to ensure the vitality of these critical ecosystems for future generations.
