What is Ocean pollution?

The world’s oceans play a vital role in sustaining life on Earth, yet they face unprecedented threats from pollution and human activities. On this World Oceans Day, let us raise awareness about the dangers our oceans face and explore actionable steps we can take to protect them.

Our oceans cover 70% of the planet’s surface and provide countless benefits to humanity. They regulate climate, generate oxygen, and serve as a habitat for a rich diversity of marine life. Moreover, oceans support economies through fishing, tourism, and transportation, making their preservation crucial for a sustainable future.

Threats and Pollution Facing Our Oceans


Plastic pollution poses a significant threat to marine life and ecosystems. Millions of tons of plastic waste end up in the oceans each year, causing harm to marine animals through ingestion and entanglement. To combat this, we must reduce our reliance on single-use plastics and adopt sustainable alternatives.


Chemical pollutants, including oil spills and agricultural runoff, contaminate the oceans, harming marine life and ecosystems. These pollutants can disrupt reproductive cycles, damage coral reefs, and contaminate the food chain. Implementing strict regulations and promoting sustainable practices are crucial for reducing chemical pollution.


 Overfishing threatens the balance of marine ecosystems and depletes fish populations. It is crucial to support sustainable fishing practices such as fishing quotas, ecosystem-based management, and the establishment of marine protected areas. By doing so, we can ensure the long-term viability of our oceans’ resources.

Supporting Greenpeace’s Work for Ocean Protection 

Consider making a donation to Greenpeace, a leading organization dedicated to protecting the world’s oceans. Your contribution will support our efforts to combat ocean pollution, advocate for marine conservation policies, and safeguard vulnerable ecosystems.

We conduct research, raise awareness, and engage in direct action to address key environmental issues.

What we fought and fight for

On March 4, 2023, a historic agreement was signed. This Treaty is a major victory for ocean conservation and a crucial demonstration that international collaboration is still possible despite the world’s growing divisions. It wasn’t simple to get, and this is just the foundation of our objectives to offer a mechanism to establish completely and very protected ocean sanctuaries on the high seas.

This was possible because of years of relentless hard work from people and allies around the world. 

Our oceans are in crisis, but together, we can make a difference.  A bright future for our oceans is only possible if we do it together — for us and for generations to come.
