More Signs of Trouble
Gajić has found that many sharks eat plastic, too. Plastic eating and shark diseases have something in common. Both are caused by pollution.
Gajić studies sharks in captivity, too.
Next Steps
Gajić has a lot of work to do studying sharks. He says there are many things that kids can do to help. Practice citizen science. Is there a beach near you? Take a walk. You may find shark egg cases. Take a photo. Upload it to iNaturalist. Help scientists learn where sharks are living.
Learn what you can do to help sharks. The more we know, the easier it will be to help all living things.
