3 Easy Ways to Celebrate World Oceans Day
On World Oceans Day, I want to reflect on one of the biggest problems facing our oceans today – overfishing. Commercial fishing practices are a significant source of stress on our oceans.
The statistics are grim: 3/4 of the world’s fish stocks are being harvested faster than they can reproduce. Eighty percent are already fully exploited or in decline. Ninety percent of all large predatory fish – including tuna, sharks, swordfish, cod and halibut – are gone. Scientists predict that if current trends continue, world food fisheries could collapse entirely by 2050.
The Dangers of Overfishing
Bottom trawling (heavy weights attached to a large net dragged along the sea floor) destroys everything in its path, including thousand-year-old coral reefs and delicate deep sea ecosystems. Shrimp trawling is one of the worst forms of commercial fishing – bycatch rates can range between 70% and 90%, entangling and drowning everything in its path, including turtles, sharks, and dolphins.
Another source of strain comes from the high demand for shark fin soup in China. One bowl of shark fin soup can fetch up to $100 or more, and scientists are realizing that these top predators are necessary to maintaining healthy marine ecosystems.

Want to do your part?
Here are three simple activities you can do to raise awareness of our oceans’ problems
- Eat sustainable fish. According to the Food and Agriculture Organization, “One in five people on this planet depends on fish as their primary source of protein.” Find out which seafood is safe for you and the oceans by reading up on seafood eco-ratings by the Environmental Defense Fund (EDF).
- Avoid plastic bottles and bags. Did you know that there is an island the size of Texas in the Pacific Ocean that is made entirely of trash? Turtles, seabirds, and other marine animals often mistake trash for food, but you can do them a favor – keep our oceans trash-free! Recycle plastic bags at grocery stores and use reusable water bottles.
- Sign up for a clean-up. If you want to get your hands dirty, join people across the globe in a nearby clean-up or organize an event near you.
