On July 25, 2020, amid the global crisis caused by the pandemic, a freight vessel collided with a coral reef on the Ile auxAigrettes in Mauritius. 1.000 tons of oil were spilled into the sea, causing an environmental catastrophe in a nature reserve of high ecological value for its diversity of unique plant, reptile, and bird species (1). A team of specialists from Jersey traveled to the scene. Upon arrival, the air was unbearable; the chemicals in the air caused by the spill required special masks and other protective gear (Figure 1), moreover the time on the island was limited to prevent intoxication. The plan was to rescue as many animals as possible. Several individuals of three endemic and threatened species were taken into safety (2). Without their rapid response, these species would probably be gone now (3).
The staff deployed in Mauritius were part of the conservation team at the Jersey Zoo (Durrell Wildlife Conservation Trust) (Figure 2), one of the zoos that had to close doors during the pandemic, as most zoos around the world did.
In recent months, many companies have resorted to telecommuting or workforce reduction to continue their activity while reducing costs to the minimum required. However, the situation is way more complex in the zoo sector; staff cannot telecommute, they have to feed and take care of their animals (4) and, in some cases, like the spill disaster in Mauritius, ensure the safety of wild species in their environment as well.
Most zoos rely on entry fees for their operations, and without visitors, the funding vanishes. Without funding, the crisis could lead to permanent closure. And so, the pandemic has been pushing the resilience of zoos for months now. Their closure doesn't just mean an end to a business; there might be consequences for the conservation of some species.
The long history of zoos goes back 4,000 years. Zoos began as private collections of exotic animals called "menageries," where animals were kept for display, religion, or showcasing the owner's wealth (5) (Figure 3). As public interest in natural history grew in the 18th and 19th centuries, zoos opened to the public (6). Although the main objective of these zoos was entertainment, they marked the beginning of scientific research and public education, which remain key objectives of modern zoos (7). In the 1960s, many zoos began to show signs of aging and disconnection with society (8).
Their survival depended on being seen as an integral and relevant part of their society. In developed countries, zoos began to respond to growing environmental and animal welfare concerns (7), and started the transition into conservation centers adopting three main objectives and justifications to maintain animals in captivity: Conservation, Education, and Research (9). Meanwhile, the updating was slower in developing countries where several welfare allegations were reported (10).
Over the past 50 years, the zoo industry has progressed significantly in animal welfare, education, and conservation (Figure 4). However, visitor perception seems to have evolved even faster, often without giving the industry enough time to adapt to a new awareness of captivity.
The reality is that the mere word "zoo" conveys impressions of ancient zoos, bad zoos, circuses, and theme park shows that many find unpleasant (11). These perceptions are most times justified, as 90% of the world's zoos do not have accreditation from their respective regional associations. In many cases, they operate with outdated procedures without considering recent advances in animal welfare or the roles they should be undertaking as conservation entities.
While the global zoo industry offers significant funding to wildlife conservation annually, 97% of the capital is raised by North American and European institutions (12). Even within these regions, only a handful of parks are responsible for generating most of the resources, considering that approximately 47% of the total funds are raised by just three big institutions (Wildlife Conservation Society, San Diego Global, and the Zoological Society of London) (13).
In short, there are "good-zoos" that play an important role in wildlife conservation and "bad-zoos" that do not contribute to education or conservation in any way; instead, they might be building up opposition to the whole industry.
The"good zoos", those that have a flawless reputation through long term projects to preserve endangered species, fighting against illegal trafficking, or contributing to scientific research, following an aspirational mission to protect biodiversity, may use their reputation for requesting help in these challenging times. For example, the ZoologicalSociety of London has managed to raise 13.5 million euros to save its zoo through an ambitious campaign led by Sir David Attenborough (14). Of course, London Zoo is special, and not all zoos have their reputation; Founded in 1826, ZSL is considered the first scientific zoo and has the honor of having been Charles Darwin's"playground". Saving the Zoological Society of London also means saving its Institute of Zoology, where hundreds of research and conservation projects are carried out in more than 70 countries. With an annual budget of more than 20 million euros exclusively for the conservation and research of threatened species, it is clear that London Zoo is collecting what it has sown for decades of good practices (13).
Nevertheless, funding is not the only resource that zoos have to protect wildlife; there are examples of smaller institutions that perform equally commendable work for biodiversity. The Jersey Zoo, for instance, with just over 200,000 visitors a year, is not a large institution. However, they are able to generate more than two million euros per year for their conservation projects in Madagascar,Brazil, or Sumatra, among others. Moreover, as mentioned at the beginning of this post, they raised funds and provided the required expertise to react swiftly during the Mauritius crisis in the middle of a global crisis (2) (Figure 7).
Dublin Zoo has also managed to raise more than a million euros through public donations (15), allowing the Zoo to remain open and continue the support of key conservation projects around the world. ChesterZoo (Figure 6) is another renown European institution that manages several successful conservation programs worldwide. Here they have established adoption programs engaging kids to adopt hundreds of animals (16).
The institutions mentioned above are nonprofit organizations. There are also private for-profit, as well as public zoos. While the search for profit might influence the operations of private entities, it doesn't mean these organizations are implementing bad practices and cannot play a major role in conservation. The Singapore Zoo is an example that profit is not at odds with progressive zoos as centers for the conservation of biodiversity. This private self-funded organization holds the reputation of being the most beloved and respected zoo by its local people (17) with world leading conservation and animal welfare practices (18). Supporting over 50 conservation projects in the most threatened ecosystems of Southeast Asia, the Singapore Zoo is also responsible for the rescue and rehabilitation of their local wildlife. In times of crisis, the Singapore Zoo has established a new foundation (Mandai Nature) to multiply its resources in the fight against biodiversity loss, showcasing a clear determination to fulfill their institutional vision (19) (Figure 8).
The lack of revenue has forced zoos to undertake different emergency plans, ranging from simple actions such as reducing non-essential staff, to highly controversial ones such as the euthanasia of animals as a last resort (20). The Indonesian Zoo Association announced that their members could be pushed, in the worst-case scenario, to slaughter some animals to feed others (21). This measure has also been proposed by a German zoo causing great shock in some sectors of the population and being disregarded, at least temporarily, after social pressure (22,23). Animal management will be a concern if zoos are to close down during the current crisis. Historically, when a zoo closed down, the animals were sent to other parks. However, this approach is not possible since all zoos are running with limited resources and cannot take on new acquisitions to the collection (4). The fate of these animals will beat stake.
Besides the future of individual animals in zoos that shut down, it is also necessary to assess the damage caused to wildlife conservation as a whole.
In the midst of the sixth mass extinction (24,25), ex-situ conservation has become a key pillar where the survival of a large number of species under conservation trouble stands (26). All UN State Members are encouraged to use ex-situ conservation as a tool to prevent extinctions according to the Article 9 of the Convention on Biological Diversity (CBD) (27). Recently, there has been a huge setback on the missing Aichi Targets of the CBD (28). Consequently, authorities of all UN member countries have been urged to take more decisive actions to tackle every Target with ambition (29). Some Targets, including 12, 13,19, and 9, are particularly relevant to zoos (29) (Figure 9). Achieving these roles requires all UN state members to push conservation initiatives forward, applying more stringent measures and supporting organizations that work on these objectives.
The shutdown of zoological institutions that never made an effort for research, conservation, and education will not result in a significant loss for any of the Aichi targets. However, we cannot afford to lose well-recognized institutions which reputation is based on defending and protecting wildlife. They are the great allies for biodiversity conservation.
