For all divers, it’s no secret that our oceans are facing a serious threat from plastic waste. This situation should never have existed in the first place. So, what exactly can divers do to contribute to reducing the amount of plastic waste in the sea?
The Current Amount of Plastic Waste in the Ocean
According to recent research, it is estimated that more than 150 million tons of plastic waste are floating in our oceans today. This includes all types of plastics, ranging from bottles to tiny fragments known as microplastics—small particles often invisible to the naked eye.
Plastic waste has devastating impacts on the marine environment. Many marine animals mistake plastic for food, which threatens their health and survival. Coral reefs and other marine ecosystems are also disrupted when plastics get trapped among reef branches.

How Divers Can Help
Now, let’s focus on how divers can play a role in addressing this issue:
- Use Eco-Friendly Equipment
Start by using environmentally friendly diving gear, such as refillable breathing tanks. This reduces divers’ contributions to plastic waste, as disposable plastic containers won’t end up in the sea. - Carry a Trash Bag
Every diver should bring a small bag during dives. If you come across plastic waste underwater, you can collect it and dispose of it properly once back on the surface. When done collectively, divers can make a real difference in cleaning up marine environments. - Join Underwater Clean-Up Activities
Divers can actively participate in underwater clean-up events. Many diving groups and marine conservation organizations organize such activities. By joining, you not only help remove existing waste but also support ongoing marine conservation efforts. - Educate Fellow Divers
While engaging with the diving community, take time to talk about the plastic waste problem and its impact on marine life. Encourage fellow divers to get involved in conservation activities. The more divers who care, the greater the positive impact we can achieve. - Support Anti-Plastic Campaigns
Numerous campaigns and initiatives focus on reducing plastic use and preserving the marine environment. You can join, support, or even donate to these campaigns. Every action helps strengthen the fight to protect the oceans from plastic pollution.
By understanding the scale of the plastic waste problem in our seas, divers can take an active role in reducing it and preserving these extraordinary ecosystems. Let’s work together to keep our oceans beautiful and healthy for future generations. (Sulung Prasetyo)
