Celebrated on June 8, World Oceans Day 2025 was observed with the theme “Wonder: Sustaining What Sustains Us”, reminding humanity of the vital role oceans play in life on Earth.

Events were held worldwide to promote marine conservation, sustainable ocean management, and awareness of ocean-related challenges.

Key Points:

• Theme:
  The 2025 theme, “Wonder: Sustaining What Sustains Us,” focused on the emotional, ecological, and economic importance of the ocean, inspiring people to reconnect with and protect the marine environment.

• History:
  World Oceans Day was officially recognized by the United Nations in 2008, though it was first proposed by Canada at the Earth Summit in Rio de Janeiro in 1992. Since then, it has been observed every year on June 8 to celebrate the ocean's role in everyday life and to inspire action to conserve it.

• Significance:
  Oceans produce over 50% of the planet’s oxygen, regulate climate, support biodiversity, and provide livelihoods to over 3 billion people. However, only 2.7% of oceans are under strong protection, far below the 30% target by 2030.

• Events and Initiatives:
  Major events included the launch of the UN Ocean Conference in Nice, France, a symbolic boat parade, and global educational and cleanup drives. In India, beach cleanups, student workshops, and conferences focused on marine biodiversity and climate resilience.

• Call to Action:
  The day served as a global rallying point to advance marine protected areas, reduce plastic pollution, promote sustainable fishing, and invest in nature-based climate solutions like mangroves and coral reefs.
