In line with Rotary’s theme of the Environment this month, members of the Rotary Club of Mount Eliza were given a rare and powerful insight into one of the most important ecosystems on Earth—a live virtual link direct from Antarctica.
Our guest speaker, Dr Stuart Kininmonth, joined us from a New Zealand research station near McMurdo Station, sharing firsthand insights into both the science and the human experience of living in one of the most extreme environments on the planet.
A Continent That Shapes the World
Antarctica is far more than a remote, icy wilderness—it is central to the Earth’s environmental systems. Holding approximately 70% of the world’s freshwater in its vast ice sheets, this continent plays a critical role in regulating ocean currents and global weather patterns.
Changes here do not stay here. Even small shifts in ice melt can influence climates across the globe, including in Australia and New Zealand.
Life Beneath the Ice
Despite its harsh conditions, Antarctica supports a surprisingly rich ecosystem. Beneath the sea ice lies a productive underwater environment, often described as a “garden,” which sustains krill, fish, and larger marine life.
One particularly fascinating phenomenon is “gigantism,” where species grow significantly larger than their tropical counterparts due to slower metabolisms in the cold.
During summer, the region teems with wildlife—penguins, seals, and orcas all taking advantage of abundant food sources. In winter, however, the landscape becomes stark and silent, with virtually no visible life on land.
Endurance and Isolation
Life at the station is defined by extremes. Summer brings 24-hour daylight and a population of up to 140 people, while winter reduces that number to just 12, with no access in or out.
Temperatures can fall below −40°C, and strict safety protocols govern movement outdoors. Even everyday tasks require planning, and simple comforts—like fresh food—become limited.
As the sun sets for the final time in April, the station enters months of darkness, replaced only by a long twilight.
A Shared Responsibility
Protected under the Antarctic Treaty System, Antarctica stands as a symbol of international cooperation and environmental protection.
However, with increasing global pressures and the presence of valuable natural resources beneath the ice, its future depends on continued stewardship and global commitment.
Bringing the Theme to Life
Dr Kininmonth’s presentation brought Rotary’s Environment theme into sharp focus. It reinforced the importance of understanding and protecting our planet’s most fragile ecosystems—and the role we all play in that responsibility.
From Mount Eliza to the far reaches of the south, the message was clear: environmental awareness is not just global—it is personal.
