Stainless steel grid frames cover the concrete structure of the new Ginza Sony Park, creating a subtle boundary with the city.
It serves as the building's facade and a structured interface that can accommodate various activities.

What can we share with the world from the corner of Sukiyabashi Crossing in Ginza, where hundreds of thousands of people pass by every day?

As Ginza Sony Park embarks on a new challenge as a "park in Ginza," we envisioned how this space could inspire reflection on both the present and the future.

Since its founding in 1978, O'Reilly's computer programming books have been beloved by engineers around the world. Affectionately known as the "Animal Books" for the diverse species featured on their covers, many of which are endangered, O'Reilly has used this unique space of the cover to raise awareness. Inspired by this bold and thoughtful initiative, Ginza Sony Park has chosen Endangered Species as the theme for this program.

In support of our initiative, we received a special message from Tim O'Reilly, the founder and CEO of O'Reilly Media, Inc.

The covers of the O'Reilly books about computer programming are one of the most iconic brands in publishing - just one more example of the unexpected and unaccounted for economic impacts of nature. Every endangered species we lose lessens not only the richness of our natural heritage but also its cultural and economic value.
Many of the animals on the covers of O'Reilly books are from 19th century engravings, a time when these animals were plentiful. Today, between habitat destruction, hunting, poaching, human/animal conflicts, and the illegal wildlife trade, many species that were abundant 100 years ago are teetering on the brink of extinction. Highlighting these animals on the cover of O'Reilly books has helped to raise awareness of the challenges faced by these creatures.

Endangered Species

There are more than 1.75 million known species of plants and animals on Earth. But many more species haven't been discovered yet, and scientists think the total number could be between 5 million and 30 million.
At the same time, many species are disappearing and becoming extinct. It's estimated that there are about 5,500 species of mammals in the world, and over 1,200 of them are classified as "endangered," which means they are at risk of disappearing. Similarly, out of the 10,000 species of birds, about 1,500 are endangered.
The world of living things is built on connections between animals that eat and are eaten by others. This connection forms what we call an "ecosystem." In a balanced ecosystem, all living things, including humans, survive and thrive.
Species are disappearing faster than nature can recover because habitats are being destroyed too quickly. Human activities are the main cause of this imbalance, but humans also have the power to help protect these animals and keep them from going extinct.

  • Animal illustration: A snow leopard depicted in monochrome.
    Snow Leopard
    Scientific Name: Panthera (Uncia) uncia
    IUCN Red ListVU
    Classification (Order and Family):
    Carnivora, Felidae
    Distribution:
    Central Asia (Mongolia to the Himalayas)
    Body length:
    86-125cm
    Tail length:
    80-105cm
    Weight:
    22-55kg
    Estimated Population:
    7,466-7,996 individuals (as of 2016)

    The snow leopard lives in the highlands of Central Asia, but it's only found in small numbers. Its thick fur helps it survive the cold. Snow leopards are most active during low-light hours, hunting wild goats, sheep, birds, rodents, and rabbits.
    The biggest threat to snow leopards is the loss of prey due to land development and other changes in their habitat. Even though trading their fur is illegal, poaching is still a problem. In areas near human settlements, snow leopards sometimes hunt livestock during winter, which can lead to conflicts with local residents, and they are sometimes killed as a result. Conservation efforts that help snow leopards and humans live alongside each other are very important.

  • Animal illustration: An African penguin depicted in monochrome
    African Penguin
    Scientific Name: Spheniscus demersus
    IUCN Red ListEN
    Classification (Order and Family):
    Sphenisciformes, Spheniscidae
    Distribution:
    Coastal regions of southern Africa
    Height:
    68cm
    Estimated Population:
    50,000 individuals (as of 2015)

    The African penguin is known for its loud call, which resembles the braying of a donkey. In the early 20th century, the population numbered in the millions. In 1930, an estimated 3 million individuals inhabited Dassen Island, the largest breeding colony on the Atlantic coast of South Africa. However, by 1963, the population had sharply declined to 140,000, primarily due to illegal egg harvesting at breeding sites.
    Since the late 1960s, many seabirds, including the African penguin, have lost their lives due to oil spills from shipping accidents. Additionally, large-scale fishing methods have led to many penguins dying after becoming entangled in drift nets, while their food sources, such as anchovies, have been heavily exploited by humans. The population decline has not been halted, and in 2010, the species was reclassified from Vulnerable (VU) to Endangered (EN) on the IUCN Red List.

  • Animal illustration: A walrus depicted in monochrome.
    Walrus
    Scientific Name: Odobenus rosmarus
    IUCN Red ListVU
    Classification (Order and Family):
    Carnivora, Odobenidae
    Distribution:
    Coastal regions of the Arctic
    Total length:
    2.7-3.6 m (males),
    2.2-3.1 m (females)
    Weight:
    800-1,700 kg (males),
    400-1,250 kg (females)
    Estimated Population:
    225,000 individuals

    Walruses live in groups, enjoy hauling out on beaches to bask in the sun, and dive to forage for food. They use the whiskers around their mouth to search through the sand on the ocean floor, feeding on bivalves and other marine organisms.
    From the 18th to the 20th century, walruses were excessively hunted for their large tusks, which can grow up to 1 meter in length and were used for crafting, as well as for their meat and hides. Walruses rely on sea ice to escape predators and raise their young safely, so the shrinking of ice due to global warming has become the greatest threat to the species in recent years.

  • Animal illustration: A Tasmanian devil depicted in monochrome.
    Tasmanian Devil
    Scientific Name: Sarcophilus harrisii
    IUCN Red ListEN
    Classification (Order and Family):
    Dasyuromorphia, Dasyuridae
    Distribution:
    Australia (Tasmania)
    Body length:
    57-65cm
    Tail length:
    24.5-26cm
    Weight:
    5-8kg
    Estimated Population:
    10,000 individuals (as of 2007)

    The Tasmanian devil inhabits forests and scrublands. During the day, it rests in underground dens, and at night, it becomes active, hunting small mammals, reptiles, and birds. Around 400 years ago, Tasmanian devils also lived on mainland Australia, but their population declined due to predation by dingoes introduced by humans. Today, they are found only on the island of Tasmania.
    Tasmanian devils were later extensively culled as pests for attacking livestock. However, in 1941, they were granted legal protection.
    In the 1990s, an outbreak of Devil Facial Tumor Disease (DFTD) led to a population decline of over 60%. This form of cancer spreads through direct contact and prevents affected Tasmanian devils from eating. A conservation program began in 2003, but developing a vaccine is expected to take time. Over the next decade, a further population decline of more than 60% is predicted.

  • Animal illustration: A Galápagos land iguana depicted in monochrome.
    Galápagos Land Iguana
    Scientific Name: Conolophus subcristatus
    IUCN Red ListVU
    Classification (Order and Family):
    Squamata, Iguanidae
    Distribution:
    Ecuador (Galápagos Islands)
    Total length:
    80-110cm
    Estimated Population:
    Unknown

    The Galápagos land iguana is active on the ground and inhabits dry lowland areas. Its primary diet consists of the fruit and flowers of the prickly pear cactus, although it sometimes eats insects and crabs.
    This species has been threatened by hunting for food and damage caused by invasive species. Many young iguanas have been preyed upon by feral dogs and cats, while plants they depend on have been consumed by feral goats. However, after the eradication of many invasive species, the population is now showing signs of recovery.
    All three species of the genus Conolophus, which include the Galápagos land iguana, are found exclusively on the Galápagos Islands. Among them, the Galápagos pink iguana (C. marthae), which is found only on Isabela Island, was recognized as a separate species in 2009. With only around 200 individuals remaining, it is classified as Critically Endangered (CR) on the IUCN Red List, indicating a highly threatened status.

  • Animal illustration: A Grevy's zebra depicted in monochrome.
    Grevy's Zebra
    Scientific Name: Equus grevyi
    IUCN Red ListEN
    Classification (Order and Family):
    Perissodactyla, Equidae
    Distribution:
    East Africa
    Body length:
    250-300cm
    Shoulder height:
    140-160cm
    Weight:
    352-450kg
    Estimated Population:
    Less than 2,000 mature individuals

    Grevy's zebra, the largest wild equid species, is found in Kenya and Ethiopia and is recognized by its narrower stripes compared to other zebras.
    The population of Grevy's zebras has declined due to overhunting for their pelts, poaching, habitat degradation, and drought. In response, hunting of Grevy's zebras was banned in Kenya in 1976. The population decreased from around 15,600 in the late 1970s to about 2,000 in 2004, and there has been no significant change in numbers since. The growing number of cattle grazing raises concerns about the loss of feeding grounds and reduced access to water sources, both of which could impact the population of Grevy's zebras.
    In addition, uncontrolled ecotourism is believed to be negatively affecting their behavior.

IUCN Red List
The IUCN (International Union for Conservation of Nature and Natural Resources) Red List of Threatened Species ("Red List") provides comprehensive information on the conservation status of a wide range of species, including vertebrates, invertebrates, and plants. It includes data on their distribution, population size, and trends, all based on quantitative criteria.
The Red List serves as a global guideline for conservation efforts.
In the Red List, species are categorized into ranks (categories) based on their risk of extinction. These ranks are determined using criteria such as the degree of habitat loss, population decline, future outlook, and the extent of their habitat. Among these categories, species classified as CR (Critically Endangered), EN (Endangered), and VU (Vulnerable) are specifically referred to as "endangered species."
EX[Extinct]/EW[Extinct In The Wild]/CR[Critically Endangered]/EN[Endangered]/VU[Vulnerable]/NT[Near Threatened]/LC[Least Concern]

Various Factors Contributing to the Risk of Extinction

  • Habitat Loss and Fragmentation
    Forests around the world are being cleared for various forms of development, including residential areas, agriculture, and grazing. Wetlands, such as lakes and marshes, are also being lost due to land reclamation and drought. The degradation and drying of wetlands, driven by drought linked to global warming, and the increase in forest fires due to rising aridity are depriving wildlife of their habitats and food sources. As animals lose their habitats, they become isolated in groups, which can eventually lead to local extinction.
  • Poaching and Overhunting
    Overhunting is the excessive capture or collection of animals for valuable or rare parts, such as meat, fur, and horns. When overhunting exceeds the natural capacity for recovery, it pushes species to the brink of extinction and disrupts the balance of the ecosystem.
  • Water Pollution in Aquatic Environments
    When freshwater ecosystems, such as rivers and wetlands, are contaminated by pesticides or factory wastewater, harmful substances can remain in the bodies of organisms living there. These toxic substances are particularly likely to accumulate in the bodies of predators. Additionally, in the ocean, waste directly endangers the lives of marine creatures.
  • Invasion of Non-Native Species
    Non-native species are animals, such as pets or other animals, that are introduced into the wild and breed in areas outside of their original habitat. When non-native species have greater vitality or a survival advantage, they may displace native species by taking over shelter and food resources.
  • Global Climate Change
    The rise in atmospheric carbon dioxide is causing global temperatures to increase beyond historical levels. This has led to the spread of previously uncommon infectious diseases and the death of coral in the oceans. In the Arctic, polar bears are losing large portions of their sea ice habitat due to global warming.
  • Infectious Diseases
    Some species are at risk of extinction due to infectious diseases. For instance, the chytrid fungus and ranavirus have led to large-scale deaths in amphibian populations. With the advancement of transportation systems in the modern era, people and goods have been traveling across the globe at unprecedented speeds and volumes. Consequently, pathogens that were not originally present in wild ecosystems have spread worldwide, concealed among humans and goods.
