That experience, supported by his parents, led him to become a full-time scuba diving instructor and advocate for environmental conservation. Through seminars and educational sessions with residents, scuba divers, fisherfolk, and social workers, Tharunsri has inspired many—including his daughter—to protect the oceans. Aarathana, growing up surrounded by her father’s dedication, found her calling early, earning her PADI certification and diving headfirst into marine conservation.
Swimming for a Cause
Aarathana’s commitment to the environment goes beyond local clean-ups. On April 3, she, her father, and seven-year-old volunteer Nishvik swam from Thalaimannar in Sri Lanka to Dhanushkodi in India to raise awareness about marine plastic pollution. This remarkable feat was part of her ‘Save the Ocean’ initiative, which also included an 11-hour, 30-minute swim to highlight the urgent need for ocean conservation. Through these efforts, Aarathana has removed over 1,200 kg of plastic waste from beaches and underwater, making a tangible impact on Chennai’s coastal ecosystems.
