want to see and saving the ones we may never see again.
Section 1: The Zoo as Sanctuary
Sumatran rhinos foraging in forests from Bhutan to Borneo.
数百年来，动物园仅仅是捕获奇珍异兽供人类猎奇观赏的笼养展馆。如今，顶尖动物园已脱胎换骨成为科学拯救中心。从布朗克斯动物园挽救的美洲野牛，到米勒公园动物园培育的红狼，圈养繁育项目屡次将珍稀物种从绝灭边缘拉回生天。
Today, there may be fewer than a hundred left in the world.
Three of these were born in Cincinnati, a female named Succi and her brothers, Harapan and
Andalus.
In 2007, the zoo sent Andalus to Sumatra, where he has since sired a calf at Wade Kambas National
Park.
If the species escapes extinction, it will in no small park be thanks to the work done
at the zoo, and what goes for the Sumatran rhino goes for a growing list of species saved
from oblivion.
Section 2: The Triage Dilemma
As the wild shrinks, zoos are increasingly being seen as modern day arcs, the last refuge against
然而，保护生物学家正面临着残酷的算术命题：资金资源与场馆空间极度匮乏。动物园无法拯救每一种走向衰落的生灵。保护主义者不得不推行生态“伤员分流法”（Triage）——严格评估哪些物种拥有健康可行的遗传多样性与重返荒野的栖息地，以证明长期昂贵圈养繁育的合理性。
a rising tide of extinction.
Who to save?
From the early 19th century, American zoos were involved in animal conservation.
At the end of the century, the Cincinnati Zoo tried unsuccessfully to breed passenger pigeons,
whose numbers were in rapid decline.
The bird, thought to be the very last passenger pigeon named Martha, died at the zoo in 1914.
The building where she lived is now a memorial.
Section 3: The Frozen Ark
North America, the Bronx Zoo started a captive breeding program that helped save the species.
为了给未来数个世纪庇护宝贵的生物遗产，科研机构正在创立“冰冻动物园”。通过将活性细胞系、卵子与精子冷冻保存在摄氏零下196度的液氮真空罐中，遗传学家永久封存了消逝物种的分子生命蓝图。一旦未来的自然栖息地得以修复，这些深低温安瓿将让逝去的生灵再度漫步于地球之上。
Other animals that owe their existence to captive breeding efforts are the Arabian Oryx, the
black-footed ferret, the Red Wolf and the California Condor.
Because such programs tend to be expensive, the Condor Program costs participating institutions
up to $2 million a year.
They usually led by large big city zoos, but smaller zoos are increasingly joining in.
The Miller Park Zoo in Bloomington, Illinois is one of the smallest zoos in the United States,
adjust for acres.
💡 6B Critical Thinking · 明星大物种 vs 隐秘小生物 (P.135)
Conservation Allocation · 有限保护资源如何公平分配
The Core Debate: Should conservation resources be concentrated on a few large, charismatic megafauna (like pandas, tigers, and rhinos), or distributed to preserve thousands of smaller, less popular species?
Arguments for Large Charismatic Species: The public adores them and donates millions; protecting their vast habitats creates an umbrella effect that shields hundreds of unseen species.
Arguments for Smaller Keystone Species: Invertebrates, amphibians, and plants are the true bedrock of ecosystems; saving them is vastly more cost-effective and preserves critical ecological functions.
Teacher's Guide · 教师用书权衡启迪
Using zoos as modern-day conservation arks is the most effective approach as long as biodiversity is treated holistically. Charismatic megafauna should serve as ambassadors to fund the unglamorous conservation of small, essential organisms.
