Nearly Extinct Rhino Species Found Only in Indonesia

The Javan Rhinoceros is one of the world’s most endangered species, with only sixty remaining in Indonesia’s Ujung Kulon National Park.

Javan Rhinoceroses used to be common throughout the continent of Asia, until poaching and habitat loss dwindled the population down to what is now a mere 60-68 rhinos, all found in Ujung Kulon National Park in Indonesia. The poaching of Javan rhinos largely began in colonial times, with the animal being a trophy for hunters. Now, the rhinos are poached primarily for their horns, which are extremely expensive and are sometimes used as status symbols among the extremely wealthy. Javan rhinos were declared extinct in Vietnam in 2010, when the last rhino in the country was poached, and now the only surviving Javan rhinos exist in Indonesia. 

While poaching Javan rhinos is illegal, and they are considered a protected endangered species, reviving the population presents a major challenge for two main reasons. The first is that the extremely small number of surviving Javan rhinos doesn’t allow for much genetic diversity. The second issue is habitat loss as a result of both human intervention and natural disaster. Human activity near Ujung Kulon National Park has interfered with the rhinos’ natural habitats, and the push  for more property development in the area threatens the security of the park. In terms of natural disasters threatening the rhinos’ last remaining habitat, the national park is located in an area that is susceptible to tsunamis and rising water levels as a result of climate change, and also happens to be near an active volcano, Anak Krakatau. Many conservationists are extremely nervous that if one of these natural disasters occured, all hope would be lost for the species even if there were a few survivors, because of the already miniscule genetic diversity within the population.

Even without the threat of natural disaster and human interference, Javan rhinos face an existing setback within their protected habitat. An invasive species called Arenga Palm grows in Ujung Kulon National Park. This plant blocks the sun, which prevents the plants that the rhinos eat from growing. The park has made clearing Arenga Palm a priority, but since it is an invasive species, eliminating it from the park entirely is not an easy task.

Ujung Kulon National Park does offer tours, providing an opportunity to ethically see the nearly extinct rhinos. However, since these tours are meant to be non-invasive, there is no guarantee that a Javan rhino will come into view during your time in the park. With that being said, tourists often see traces of the rhinos, such as footprints, like in the photo featured above. 

Get Involved

The best way to get involved with this issue is to raise awareness and money for organizations working to sustain and increase the population of Javan Rhinoceros. Some of these organizations include World Wildlife, which is working on eliminating Arenga Palm and also hopes to one day transfer some Javan rhinos to an area which is not in the danger zone of the volcano Anak Krakatau. Another good organization to support is the International Rhino Foundation, which works directly with the staff of Ujung Kulon National Park. On a more general level, raising awareness about climate change and supporting organizations which respond to extreme weather is a way to get involved with this issue as well as many others, as climate change has only compounded the plight of the Javan Rhinoceros.

The Danger of Selective Dog Breeding

Selective breeding has produced many of the dog breeds we know and love today, but also poses a serious threat to their safety.

Out of the over 300 dog breeds alive today, many are the result of a process called selective breeding. Dating back almost 200 years, the practice has resulted in many of these breeds developing significant health problems as a result of their breeding. Breeders bred dogs to create or accentuate physical characteristics that were considered aesthetically pleasing to their customers, like the tiny physiques of toy and teacup poodles or the flat faces of French bulldogs.

 Selective breeding describes the specific selection of dogs to mate in order to produce a litter with specific traits. In theory, this will allow breeders to add, remove or change various characteristics of the offspring depending on what their clients are looking for. This, of course, takes place in contrast to natural breeding which is when the mating process between the dogs is left up to them.

The motivations behind selective breeding fall broadly into two categories, the first being the desire to breed purebred dogs. In order to have a litter of purebred puppies, breeders must ensure that both parents come from pure lineages of the breed in question. This type of breeding largely occurs when buyers are looking to show their dogs at competitions, although some may simply have a preference for purebreds.

 The second main cause of selective breeding has to do with the addition, removal or reinforcement of certain traits. By mating a dog that displays a certain dominant trait with one that doesn’t, breeders can introduce the trait into the lineage. Similarly, if breeders are trying to produce dogs that are specifically skilled in certain areas -- hunting, trainability or strength, for example -- they will likely choose to mate dogs that display these traits in order for the offspring to receive them as well. Conversely, by mating a dog with an undesirable trait with a dog that doesn’t, it will be much less likely for the offspring to display the trait. This last technique is often done when breeders are trying to remove traits for certain heritable diseases.

While there can be benefits to selective breeding like preventing the inheritance of certain disease-causing genetic traits, the process is still a very controversial one because of the many dangers associated with it. Most prominently among these are the many unethical breeders who treat their dogs very badly in order to maximize the production of offspring. Because selective breeding can be a very lucrative business, especially when producing purebred puppies that will go on to compete, it is extremely important to choose a breeder who prioritizes the health and safety of the dogs over their profit. It is also very important to find breeders who don’t engage in inbreeding (forcing dogs who are related to one another to mate), as this can cause a variety of health problems ranging from decreased immunity to genetic disorders.

Bulldogs are one of the many breeds of dog that have arisen from selective breeding. Stockvault. CC0.

Breeding dogs that are too genetically similar can also worsen pre-existing health conditions in the parent dogs. A very common example of this occurs in bulldogs which were selectively bred in order to accentuate their stout physiques. Their skulls were enlarged, snouts and legs shortened and underbite exaggerated, all to produce a dog that looked appealing to customers. The breeding is so extreme that almost 95% of bulldog births must be achieved by Cesarean section because the puppies’ heads are too large for the mother to give birth naturally. Their flattened faces tend to cause respiratory problems, while their excessive folds of skin can result in skin infections and eyelid problems. Their forcibly shortened limbs and tails often develop joint problems, and their eyesight may also be compromised due to the weight of the excessive skin around their faces.

All of these health issues can be directly traced back to the selective breeding that created the breed in the first place, and bulldogs are just one of many such examples. Until money stops flowing into the industry however, putting a complete end to selective breeding will prove extremely difficult.

TO GET INVOLVED

Many animal rights groups have long been advocating for the end of selective breeding given the potential risk to the dogs. Prominent among these are People for the Ethical Treatment of Animals (PETA), a group which has long demonstrated against animal abuse and the wrongful breeding practices. The Dog Breeding Reform Group (DBRG) has published a number of welfare reports on the state of dog breeding in the UK. The Universities Federation for Animal Welfare (UFAW) also provides a number of resources to prospective pet owners about the dangers of selective breeding and better alternatives.

Entertainment or Exploitation? Dive Into Sea Mammals in Captivity 

Marine mammals living in captivity may appear happy and healthy, but the harsh reality is the aquatic entertainment industry exploits the animals for profit. Here’s why they deserve to roam free.

The definition of a cetacean is a marine mammal, but they are better known as dolphins, porpoises and whales. While not everyone has viewed these creatures in their natural habitats, there is a good chance they have been seen closer to home at a local zoo or aquatic institution. However, these businesses are in possession of cetaceans for entertainment purposes, not the well-being of the actual animals. 

As breathtaking as it may be to see an orca, whale, or dolphin right in front of your face, these creatures have complex ways of thinking and living that cannot be maintained in a glass tank. Cetaceans are social animals, similar to humans, who thrive off interacting with other aquatic mammals. They are also extremely intelligent and need space to explore new concepts and create families. If kept in captivity and separated from their offspring, cetaceans suffer similarly to what a human may experience if they are depressed or anxious: physical ailments, raised stress levels, aggressive temperaments and even premature death. As a result, this changes the demeanor of the animals, and several trainers have been injured or killed over the years. Organizations using cetaceans for entertainment purposes overlook the basic needs of these animals and forgo moral and ethical standards for the benefit of their business. 

SeaWorld is famous for its orca shows, dazzling spectators with what seem to be displays of happy creatures performing tricks willingly but are truly a collection of unhappy animals working for food in unsuitable tanks. Years of cetacean exploitation in this organization—and ones similar to it—were masked as research. SeaWorld claimed to save marine animals who had been injured in the wild by bringing them to their facility and rehabilitating them in a controlled environment. Upon further investigation, these claims were false, as some animals had been forcefully taken from their homes rather than rescued. Companies battled with lawmakers for years over the proposal of a law that would benefit the animals more than the humans in charge of them. The Orca Protection and Safety Act was passed in 2016, banning the breeding, capturing and performing of orcas in California. SeaWorld’s long reign amongst aquatic entertainment organizations crumbled. 

While several states have adopted laws banning the breeding of orcas since then, there are still 59 whales in captivity across the globe and numerous other dolphins and beluga whales in the same situation. In recent years, China and Russia have become popular locations for orca breeding and performing.

One organization in Canada is now working to rectify the unethical treatment of these animals by creating a space for them to retire and return to the life a cetacean would normally live. The Whale Sanctuary Project is dedicating their time to supporting cetaceans bred and raised in captivity who may be retired, but have no home or family to return to. The Whale Sanctuary Project creates authentic sanctuaries for these animals, large bodies of water with adequate depth where whales, dolphins and porpoises can roam free and interact with other creatures in the same situation. Their work is the first of its kind in North America and will continue to improve the lives of cetaceans in need for years to come.
