The oceans are not only a breathtaking natural spectacle, but also essential pillars of life on Earth. Ocean health directly affects climate balance, biodiversity, and yes, our own health too. More than 50% of the oxygen we breathe is produced in the seas, and millions of people rely on them for food and employment.
Despite their importance, the oceans are in danger. Pollution, overfishing, plastic waste, and the effects of climate change are seriously threatening their balance. That’s why protecting ocean health has become a global environmental emergency—and each of us can do something, especially when we visit the beach.
Why does ocean health matter?
The oceans regulate the global climate, absorb 30% of the CO₂ emitted by human activity, and provide a home for thousands of species. However, this capacity has a limit. A sick ocean means more intense storms, species extinction, and risks to the food security of millions of people. Ocean health is not a distant issue—it affects us economically, socially, and personally.
Additionally, microplastics and other pollutants have already made their way into our food chain. Many seafood products contain toxic residues resulting from marine pollution. So, what we throw into the sea ends up coming back to us, literally.
What can we do when we go to the beach?
Every visit to the beach is an opportunity to protect ocean health. Here are some simple but effective actions:
- Don’t leave trash behind: pick up everything you bring with you, including cigarette butts and small wrappers.
- Active cleanup: if you find trash, pick it up even if it’s not yours. You can bring a reusable trash bag.
- Avoid single-use plastics: bring your own bottle, utensils, and reusable containers.
- Respect the natural environment: don’t step on dunes, don’t pull up seaweed, and don’t touch marine wildlife.
With small conscious habits, you contribute to improving ocean health and preserving an environment we all depend on.
Sunscreen and sustainability
One little-known fact is that many sunscreens contain chemicals like oxybenzone, which negatively affect coral reefs and other marine organisms. Choosing a “reef-safe” sunscreen is another way to protect ocean health.
You can also opt for natural umbrellas, UV-protective clothing, and limit sun exposure during peak hours, thereby reducing the use of products that dissolve in the water.
Responsible tourism: part of the solution
Poorly managed coastal tourism can worsen problems, but responsible tourism can be part of the change. Support local businesses that promote sustainability, respect environmental regulations, and avoid activities that harm marine wildlife, such as touching turtles or feeding fish in protected areas.
Promoting ecotourism is a way to strengthen the local economy while protecting ocean health. Additionally, many organizations organize beach cleanups and educational activities where you can actively participate.
Educate to protect the ocean health
Children learn by imitation. Instilling respect for nature in them and teaching them not to leave waste, to differentiate types of plastics, or to pick up trash as a game is an investment in the future. Environmental education is key to ensuring that future generations continue caring for ocean health.
You can make it fun and interactive. For example, challenge them to “who finds the most trash” or tell them stories about marine animals affected by pollution.
Technology and knowledge in service of the sea
Today, there are apps that allow you to report marine trash, measure water quality, and even sponsor coastal areas to keep them clean. Technology offers us tools to better care for ocean health with real-time and collaborative information.
You can also check interactive maps about marine biodiversity and follow initiatives from NGOs like Surfrider Foundation, Oceana, or Greenpeace to stay informed and participate from home or your mobile device.
Your impact matters in the ocean health
Ocean health doesn’t depend only on major political decisions but also on our daily actions. Going to the beach can be more than just enjoying the sun—it can also be a gesture of commitment to the planet.
Remember, the sea starts in our hands. Taking care of it is taking care of ourselves. The next time you go to the beach, keep in mind that your behavior can make a difference. Because there is no well-being without the planet, and no planet without healthy oceans.
