12. How You Can Help Aquatic Mammals

Ocean ecosystems are facing big challenges, and your actions can help a lot. Every year, about 1.7 million tonnes of plastic go into our oceans. Only about 10% of plastic waste is recycled. So, what you choose to do matters a lot for the ocean.

Start by using less plastic and help groups that protect marine mammals. The ocean is home to 50-80% of all life on Earth. We all need to work together to lessen the harm we cause. By thinking about what we buy and how we throw things away, we can help protect marine animals.

Supporting Conservation Organizations

Many good groups that protect the sea are looking for volunteers and donations. Places like Oceana, Sea Shepherd, and the Marine Mammal Center are always busy helping. Your money or time can help fund important work to save endangered sea creatures.

Reducing Plastic Use

Try to use less plastic by choosing things you can use again, joining beach cleanups, and supporting green businesses. Since most ocean pollution comes from land, what you do can make a big difference. It helps keep the sea and its creatures safe.

Advocacy and Awareness

Help spread the word about saving marine mammals on social media, at events, and in talks. Knowing that the ocean supports 10-12% of the world’s people shows how vital it is to protect it. Your words can lead to big changes and help us take care of our planet.
