To get started, share your choice to reduce single-use plastic in your everyday life.

Welcome to Dumb Ways to Kill Oceans.

We are gaming for a better world. And the world starts with our Oceans. Together, we can play, learn and pledge to take action for some of the world's biggest challenges. The UN Global Goals are at Playmob's core and preservation of our oceans (Goal 14 - Life Below Water) is central to our planet's survival. We are passionate about empowering people through play and so are our partners - thank you to each and every one of you that has made this campaign possible. Play, Have Fun. And Let's Save Our Oceans. One Game At A Time.

Over the last 10 years we have produced more plastic than during the whole of the last century. Plastic wraps our food, our houses, and our technology. It is a remarkable substance that has contributed to advances in healthcare and helped raise millions of people out of poverty.

But, disposable consumer goods end up – often after a single, fleeting use – in landfills, littering our landscapes, and polluting our Ocean. 80% of marine plastic pollution originates from land-based sources and plastic accounts for 10% of the total waste we generate. Plastic finds its way into our oceans via our waterways, killing marine life, forming swirling gyres (the largest off the coast of California is twice the size of Texas!) and taking 500-1000 years to break down.

It is up to each of us to make smart choices, reuse and refuse. Seek out alternatives and lobby for bans on single use plastics. Together we can turn the plastic tide!


All life on earth depends on our oceans. And if the oceans are the lungs of our planet, then the reefs are the heart of our oceans. Corals are living organisms—they can get sick and die, just like any other plant or animal.

Coral reef destruction is defined as the mass death of the ocean’s corals. It is normally caused by illegal fishing techniques, pollution, careless tourism, and of course, climate change—the culprit responsible for our warmer oceans and the main reason behind the death of nearly half of the Great Barrier Reef’s corals.

But each of us can play our part by respecting the precious corals when we snorkel or dive on holiday, choosing the right sunscreen (some sun tan lotions have been shown to poison coral) and always opting for sustainably sourced fish.


The knock on effect of ocean warming is grave, threatening food security and livelihoods for marine and human lives, impacting severly on some of the most vulnerable people around the world.

Ocean warming also leads to melting of ice sheets in our polar regions, which in turn causes sea levels to rise. These implications are dire, as when sea levels rise rapidly, as they have been doing, even a small increase can have devastating effects on coastal habitats. As seawater reaches further inland, it can cause destructive erosion, wetland flooding, aquifer and agricultural soil contamination, and lost habitat for fish, birds, and plants. Some low-level islands in the Pacific are even at risk of disappearing.

The biggest responsibility lies at government level to uphold the Paris Agreement on Climate Change. But we can all do our bit - take the car less, choose renewable energies and ... (yes!) eat less red meat. Do you know how much carbon dioxide a cow produces?!
