As the world comes together to celebrate World Ocean Day on June 8, it’s a time not just for reflection and appreciation of our planet’s vast blue heart, but also for renewed commitment to protecting it. Covering over 70% of the Earth’s surface, the ocean is a source of life, climate regulation, food, oxygen, and cultural connection for billions of people. Yet today, it faces unprecedented threats from human activity.

The Importance of Our Oceans

The ocean produces more than 50% of the oxygen we breathe and acts as a massive carbon sink, absorbing about 30% of the carbon dioxide produced by humans. It regulates global temperatures and weather patterns, supports a rich diversity of marine life, and provides sustenance to more than three billion people who depend on fish for protein.

Beyond its ecological role, the ocean contributes more than $1.5 trillion annually to the global economy through fisheries, shipping, tourism, and more.

Alarming Signs of Decline

Despite its vital importance, the ocean is suffering from the pressures of climate change, overfishing, plastic pollution, oil spills, deep-sea mining, and habitat destruction.

• Climate change is warming ocean waters, disrupting marine ecosystems, and causing widespread coral bleaching.

• Plastic pollution has reached crisis levels. Millions of tons of plastic enter the ocean each year, affecting marine life at every level of the food chain.

• Overfishing continues to decimate fish populations, leaving ecosystems unbalanced and coastal communities vulnerable.

Among the most heart-wrenching casualties of these human impacts are the whales—the majestic giants of the sea.

Whales in Peril

Once hunted to the brink of extinction, many whale species have made a remarkable comeback thanks to international bans on commercial whaling. But the fight for their survival is far from over. Today, whales face new and deadly threats.

Ship strikes, entanglement in fishing gear, ocean noise pollution, and climate-induced prey shortages are all contributing to declining whale populations. In some regions, commercial whaling has shockingly resumed, often under the guise of “scientific research.” Countries like Japan, Norway, and Iceland continue to hunt whales despite international condemnation and scientific evidence warning of their vulnerability.

In 2023 alone, hundreds of whales were reportedly killed, raising serious concerns among conservationists and marine scientists. This continued hunting not only threatens whale populations but undermines global efforts to protect marine biodiversity.

A Call for Action

World Ocean Day 2025 comes with a clear message: the ocean needs us now more than ever.

Governments must enforce stronger marine protection laws, expand marine protected areas (MPAs), and take swift action to phase out harmful subsidies that promote overfishing. The international community must hold whaling nations accountable and invest in sustainable alternatives for communities dependent on the practice.

Public awareness and grassroots action are just as crucial. Individuals can make a difference by reducing plastic use, supporting sustainable seafood choices, participating in beach cleanups, and advocating for stronger ocean conservation policies.

Looking Ahead

There is still time to turn the tide. Innovations in marine science, increased global cooperation, and rising public consciousness offer hope for the future of our oceans and the life they sustain. On this World Ocean Day, let us not only celebrate the beauty and bounty of the seas but also take meaningful steps to ensure they thrive for generations to come.
