In brief
A feature published by Xinhua, recounting a visit to Kew Gardens, emphasizes Kew’s role in preserving global plant biodiversity, its historic time capsule beneath a tile, and the urgency expressed at COP17. The article details the Palm House’s living rainforest, structural challenges, and China’s collaboration, while questioning how to safeguard biodiversity by 2030 and live in harmony with nature by 2050.
A recent visit to the Royal Botanic Gardens, Kew, highlighted the urgency of biodiversity conservation, according to a feature published by Xinhua on 31 October 2026.
He described Kew as an institutional "living rainforest in London," noting that the garden, originally part of the private grounds of King George II, began its botanical collection in 1759 and now houses some 17,000 plant species. Kew was inscribed on the UNESCO World Heritage List in 2003 and serves as a global hub for plant research and conservation.
The feature draws attention to a dark‑blue tile in the Princess of Wales Conservatory. In 1985, British naturalist David Attenborough buried a time capsule beneath it, containing seeds of endangered plant species intended to be opened in 2085. Xinhua notes that scientists fear some of those species may already have disappeared from the wild before the capsule can be retrieved.
The Xinhua article frames the urgency of action within the context of the 17th meeting of the Conference of the Parties to the Convention on Biological Diversity (COP17) held in Yerevan, Armenia. "How can biodiversity be safeguarded and humanity's relationship with nature restored?" the article asks. "And how can the world achieve the goal of halting and reversing biodiversity loss by 2030 and living in harmony with nature by 2050?"
Kew’s Living Rainforest and Structural Challenges
The Palm House—a Victorian greenhouse opened in 1848—houses more than 1,000 tropical and subtropical plant species, including the Eastern Cape giant cycad from South Africa and a Pandanus tree from Australia whose above‑ground roots reach human height. Staff member Leaf explained that the greenhouse maintains consistently high temperatures and humidity levels of around 80 percent to protect the tropical plants. However, rust and peeling coating on the building’s framework expose the structure to ongoing deterioration despite two major restoration projects in the 20th century. Leaf said the Palm House was scheduled to close for renovation starting next year.
Outside the Palm House, autumn temperatures have forced the removal of plants less suited to cooler weather, making way for species with winter resilience. These seasonal adjustments illustrate the garden’s continual adaptation to climate, a theme that runs through Xinhua’s description of Kew’s conservation work.
Seed Banking and International Collaboration
The feature highlights Kew’s extensive seed bank, one of the world’s largest, and its international collaborations, especially with China. The partnership aims to safeguard plant genetic diversity for future research and restoration efforts. Xinhua emphasizes the garden’s role as a neutral ground where science and society intersect, noting that public engagement activities emphasize the societal imperative of conservation.
Regarding the future, the article raises open questions about how biodiversity can be effectively preserved in a rapidly changing world. The COP17 forum underscored the need to halt biodiversity loss by 2030 and to live in harmony with nature by 2050—goals that Kew’s work, including its seed bank and time capsule initiative, seeks to support.
Lastly, the article notes that the Palm House’s scheduled closure for renovation will test Kew’s capacity to maintain its living collections and infrastructure for the next generation. The garden’s leadership faces the dual challenge of preserving its historic structures while expanding its role as a global conservation hub.
