How to Care for the Ocean | National Geographic

Summary

Our oceans, which cover 71% of the Earth's surface, are under threat from overfishing, plastic pollution, and habitat degradation. Every year, billions of pounds of wildlife are taken from the sea, and plastic waste harms marine life. Individuals can help by making responsible seafood choices, reducing plastic use, participating in shoreline cleanups, and supporting marine protected areas. Every action, no matter how small, contributes to preserving these vital ecosystems for future generations. Learn how you can make a difference in ocean conservation and protect our planet’s most valuable resource.

Takeaways

• 😀 Our oceans cover 71% of the Earth's surface and are a vital source of food, recreation, and biodiversity.
• 😀 The balance of ocean ecosystems is fragile and increasingly threatened by human activity.
• 😀 Overfishing is a major problem, with fishing yields decreasing every year since 1989.
• 😀 Unsustainable fishing practices disrupt the food chain and affect marine life across the ocean.
• 😀 Choosing sustainable seafood helps protect the oceans and supports responsible fishing practices.
• 😀 Sustainable fishermen leave enough fish in the ocean to maintain healthy populations and minimize bycatch.
• 😀 You can find sustainable seafood guides online to make responsible seafood choices at grocery stores, markets, and restaurants.
• 😀 Reducing plastic waste is crucial, as plastic pollution harms marine life and ecosystems.
• 😀 Simple actions like bringing reusable bags, buying in bulk, and using alternatives to plastic can help reduce ocean pollution.
• 😀 Participating in local cleanups or supporting marine conservation efforts can help protect shorelines and reduce ocean waste.
• 😀 Supporting marine protected areas during travel contributes to the global effort to preserve ocean health for future generations.

Q & A

Why are the oceans important to life on Earth?

Oceans cover 71% of the Earth's surface and provide food, recreation, and an incredible abundance of life. They support ecosystems that are vital to the planet's health and human survival.

What are the main threats facing our oceans today?

The main threats to our oceans include overfishing, plastic pollution, and habitat destruction. These threats disrupt the balance of marine ecosystems and endanger marine life.

How does overfishing impact ocean life?

Overfishing removes fish from the ocean at unsustainable rates, leading to the depletion of fish populations. This disrupts the marine food chain and negatively affects all sea life.

What does sustainable seafood mean?

Sustainable seafood refers to seafood that is caught or farmed in ways that preserve ocean ecosystems and ensure fish populations remain healthy. It helps maintain the balance of marine life and supports long-term seafood supply.

How can individuals help combat plastic pollution in the ocean?

Individuals can reduce plastic waste by using reusable bags, buying in bulk, choosing bio-plastics, glass, or paper products, and recycling properly. Holding on to plastic waste until a recycling bin is available can also prevent waste from reaching the ocean.

What are marine protected areas (MPAs), and how do they help?

Marine protected areas are regions of the ocean designated for conservation and sustainability. They are managed to protect biodiversity, prevent overfishing, and maintain healthy ecosystems, helping to ensure the long-term health of marine environments.

How does plastic waste affect marine life?

Marine animals can mistake plastic for food, leading to ingestion and poisoning. Plastics also release harmful chemicals in the ocean that can damage habitats, affect marine food chains, and contaminate seafood.

What is the connection between plastic waste and overfishing?

Both plastic pollution and overfishing contribute to the degradation of ocean ecosystems. Plastic waste harms marine life directly, while overfishing disrupts food chains. Together, they weaken the health of the oceans and make it harder to sustain marine biodiversity.

How can supporting sustainable fisheries help the ocean?

Supporting sustainable fisheries helps preserve fish populations by ensuring that fishing practices do not deplete stocks or damage ocean ecosystems. These fisheries leave enough fish in the ocean to maintain a healthy balance and protect other marine species.

What role do consumers play in ocean conservation?

Consumers play a critical role by making informed choices, such as selecting sustainable seafood, reducing plastic consumption, and supporting environmentally responsible companies and initiatives. Every purchase decision has the potential to impact ocean health positively.
