Growing up in the Italian Alps, Tania Pelamatti developed a love of nature, but she had to explore a different environment before she found her true passion. “When I started SCUBA diving, I discovered this amazing new space,” she remembers—and that space inspired her.

Tania describes multiple encounters with underwater wildlife, but says one changed her life forever. Sharing a picture of fish swimming in front of her, she indicates the outline of a whale shark that approached her. This was the encounter that encouraged Tania to become a marine biologist and help ocean creatures. She made her choice, enrolled, and eventually found herself in the waters off Baja California, working with fisherman and handling live sharks. At one point, she was able to help remove a net from the species that inspired her—a whale shark.

Later, in the waters near Revillagigedo Archipelago, Tania encountered her first manta ray, and decided that was the species she wanted to work with. Impressed by their need to filter hundreds of gallons of seawater per minute to feed on plankton, she began to question what else they might be ingesting—such as plastics. She conceived of her PhD project, collecting and analyzing plastics and microplastics from manta rays’ habitats in the middle of the Pacific Ocean. “We got surprised because

In the middle of the ocean, in these remote islands, we found a lot of plastics,” she says. “Plastics reach every corner of our world.”

Tania returned home and found plastics in the Mediterranean Sea, so she stayed in Italy to work with the Italian National Institute for Environmental Protection and Research (ISPRA). Together, they monitor and propose guidelines to reduce the amount of plastics in the Mediterranean—in turn reducing the threat to underwater wildlife.

About Tania Pelamatti

Tania is a marine biologist and National Geographic Explorer who is dedicating her PhD project to the study of manta rays and their possible interaction with plastic debris. She grew up in Italy where she studied biology and holds a master’s degree in marine biology. She left Italy in 2014 to develop her master’s thesis at the Centro Interdisciplinario de Ciencias Marinas (CICIMAR-IPN) in Baja California Sur (Mexico), focused on elasmobranch’s reproductive biology. During her internship in Mexico she became very passionate about sharks and rays, and realized how vulnerable they are to human pressure, habitat loss and ocean pollution. After an amazing encounter she had with oceanic manta rays in the Pacific Ocean, she decided to continue her studies focusing on the threats they are facing in our changing oceans.

About Women Blaze Trails Festival:  

In celebration of the International Day of Women and Girls in Science (February 11), LenovoEDU sponsored Women Blaze Trails, a virtual 3-day festival celebrating women in science, exploration, and conservation from around the world.  

The virtual festival had one simple goal: celebrating incredible women, and doing incredible things around the world, day in and day out. We’re sharing these videos from the festival so you can meet scientists, explorers, conservationists, filmmakers, photographers and more, showcasing their work, challenges, adventures, research and expeditions.

  • Sadly most people don't even know the meaning of "civic sense", and that's the reason we can find plastic waste everywhere, with bad consequences for marine ecosystems. I don't know if it would be practicable, but in my opinion there should be stricter controls by governments on the uncivil behaviour of citizens, punishing whoever damages the environment.

  • plastic became a great threat environment and a dangerous invention of the century. sadly usage of plastic became necessary and no matter how much governments try to control but it's not happening. people should have individual responsibility and environmental consciousness and safe alternative should be invented. only then this issue will be reduced,
