Teen Makes A Splash With Ocean Cleanup

So far, she has removed over 7,000 kg of plastic waste from the ocean floor. Delivered more than 100 awareness talks across schools, colleges, and community platforms and completed long-distance swims, including a crossing from Sri Lanka to India, all while using her platform to advocate for marine conservation.

Growing up in Chennai, Thaaragai's childhood looked different from other children. While others had weekends spent in malls or family dinners, she was out by the shore, accompanying her father on beach clean-ups and diving expeditions. The ocean wasn’t just a place she visited; it shaped her discipline and gave her a routine. “My father says I was introduced to water on the third day after I was born,” she says. By six months, she was floating. By two and a half, she was swimming in the sea.

Deep Sea Saviour

She began diving at a young age alongside her father, Aravind Tharunsri, a scuba instructor and environmentalist. “I always dive with my father, and because of that, I have never been afraid of the water,” she says. During her diving routine near Rameshwaram, Thaaragai encountered more than just fish. “I saw plastic everywhere… and a dugong trapped in a ghost net.” There were floating bottles, tangled nets and a mother dugong that lost her life caught in debris, leaving only her baby to survive with injuries.

For Thaaragai, it was a sight that held her breath. That dive didn't just bring shock to her but also a sense of reality. “I decided that is not how our ocean should look,” she says.

A Threat Not Just Trash

From seabirds to turtles, the impact of this is widespread. Plastic blocks digestive systems, causes starvation, and entangles marine life in deadly traps like ghost nets. This traps life underwater in a deadly sight that’s impossible to ignore. The source of the problem is single-use plastics, convenience culture, and the assumption that disposal equals disappearance.

Between school, training and environmental work, Thaaragai tries to follow a disciplined routine. “If we want to do something special for the environment, we have to balance everything—school, diving, and life,” she says.

Her stride is steady and determined. As a child, she endured teasing while cleaning streets with her father. Her father encouraged her to ignore the negativity and focus on her work. Thaaragai’s message is surprisingly simple: “Say no to plastic. Carry your own bottle and bag. Be part of the solution, not the pollution.”

What Lies Beneath

She encourages others, especially youngsters, to take ownership of something. It doesn’t have to be the ocean but a species, a cause or even a space. She says, “I chose the dugong.” “Everyone can choose something – an animal, a bird or a tree. Protect it.” After all, the ocean doesn’t need saving by one person; it needs responsibility from everyone.

Discarded items don’t simply vanish; they drift, sink and return in unexpected ways. The ocean holds its memories, transcending the roles of diver and activist. It’s a relationship between humans and the often-overlooked natural world stretching deeper than we realise. Perhaps if we listen closely, it’s urging us to change.

Shell Shocked

• An estimated 82–358 trillion plastic particles are floating on the ocean surface.

• Today our oceans hold up to 199 million tonnes of plastic, with over 11 million tonnes added every year.

• Most of it sinks and is unseen, out of sight but never gone.
