On 11 May, in Hiroshima, the Antarctic Treaty consultative meeting has brought together representatives from nearly fifty countries to discuss the peaceful governance and environmental protection of Antarctica. The treaty, in force since 1961, promotes scientific cooperation while banning military activity and freezing territorial claims. This year’s discussions focus on rising tourism, climate change, and threats to fragile ecosystems, including the decline of sea ice and conservation of emperor penguins. Japanese officials hope the gathering will strengthen international cooperation and transparency in Antarctic activities. Alongside diplomatic talks, former researchers shared experiences of Antarctica’s harsh conditions with local residents, highlighting both the challenges of scientific work there and the importance of preserving one of the world’s most vulnerable environments for future generations.
