Sustainability is often viewed as an environmental responsibility, but I believe it is much more than that. It is about creating a future where people, businesses and communities work together to solve global challenges. The United Nations Sustainable Development Goals provide a shared framework for achieving this, demonstrating lasting progress depends on collaboration rather than isolated action.
Beyond this, I would argue that travel is one of the most powerful ways to understand why sustainability matters. News often exposes global crises but rarely allows us to experience their reality. In today’s world, if an issue is not directly affecting us or someone we know, it is often ignored. Meryl Streep’s UN speech describing how “Today in Kabul a female cat has more freedom than a woman” highlighted how easily injustice becomes distant rather than urgent. Travel challenges this by encouraging us to engage directly with communities and build a deeper understanding of the global inequalities the SDGs seek to address.
This belief was reinforced through my volunteering in Costa Rica. I worked alongside local communities helping to construct toilets and water facilities for children, bringing to life the importance of Goal 6: Clean Water and Sanitation. Experiencing this first-hand transformed sustainability from an abstract concept into a personal responsibility while reinforcing the importance of Goal 14: Life Below Water and the need to protect marine ecosystems from pollution.
My volunteering also extended to NATUWA wildlife sanctuary (https://www.natuwa.com/language/en/?utm_source=chatgpt.com) where I cared for animals that had suffered from mistreatment. Protecting biodiversity lies at the heart of Goal 15: Life on Land, and it became clear that environmental sustainability cannot be separated from wildlife conservation. One of my most memorable experiences involved helping protect sea turtle nests during the night in Santa Teresa, walking along beaches in torrential rain with only head torches to guide us (https://cirenas.org/). It reminded me that meaningful conservation is rarely achieved through one significant action, but through the collective efforts of individuals committed to creating lasting change.
Alongside experiencing a new culture and broadening my education, I hope to volunteer with the Great Barrier Reef Marine Conservation Project in Cairns through International Volunteer HQ (https://www.volunteerhq.org/gb/destinations/australia/great-barrier-reef-conservation/). Working alongside marine biologists and conservationists would allow me to contribute directly to protecting one of the world’s most important ecosystems, supporting both Goal 13: Climate Action and Goal 14: Life Below Water. The Great Barrier Reef supports thousands of marine species while providing livelihoods for countless communities, yet it continues to face threats from climate change, pollution and habitat degradation. Reading about coral bleaching is one thing; witnessing these challenges first-hand will provide a perspective that no textbook or documentary can offer.
Ultimately, sustainability is not simply about reducing waste or protecting wildlife. It is about recognising our shared responsibility for creating a more equitable and resilient future. My experiences in Costa Rica taught me that meaningful change begins with understanding, while my future experience in Australia will allow me to continue contributing to the global ambitions of the SDGs.
