Sub-Antarctic islands are some of the rarest ecosystems on the planet and therefore are highly significant. Around 200 years of human
activities have left a legacy of substantial impacts. We explore these under the collective headings of resource harvesting, local impacts and
habitat loss, homogenisation of biota and human-influenced climate change. Past human activities such as sealing and whaling have left
seal species still in recovery phases, and infrastructure that continues to break down and pollute the local environment. Modern-day scientific
stations have variously-sized footprints of buildings and tracks, and legacies of contaminants, particularly oils spills. On some islands,
alien species have established and there is a range of impacts associated with such taxa ranging from transient to extensive, permanent
transformation of ecosystems. Such impacts are being confounded by human-induced climate change. By projection, it is expected that
both direct and indirect human impact will continue into the future. It is appropriate to plan all future human activity in ways that will
minimise further burden on these ecosystems.
