Kangaroo industry

Kangaroo industry is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kangaroo industry rather than just read about it. In short: The kangaroo industry in Australia is based on the regulated harvesting of species of kangaroos. Products Kangaroo meat Australia commercially produced kangaroo meat since 1959.

Key takeaways

  • Kangaroo industry belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kangaroo industry to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kangaroo industry from memory before moving on to harder problems.

Reference excerpt

The kangaroo industry in Australia is based on the regulated harvesting of species of kangaroos.

Products

Kangaroo meat Australia commercially produced kangaroo meat since 1959. Annually about 3 percent of Australia's 50 million kangaroos are utilized for their meat, which is served in many Australian restaurants and sold in some supermarkets. It is also exported to over 60 countries overseas. Various pet food companies offer animal feed based on kangaroo or including kangaroo. Since kangaroos emit smaller amounts of methane compared to cattle and sheep, their meat is sometimes advertised in this context. Australia's beef industry is estimated to account for about 11 percent of the country's carbon emissions.

Kangaroo leather Various products are made from the skins of the animals. Kangaroo leather is a strong, light leather, which is more stretchy than goat or cattle but also wrinkles more easily and darkens faster. It is commonly used for shoes, motorcycle suits, handbags, wallets and in whips. Big brands usually market it as “k-leather”. Since many people see kangaroos as pest animals (and numbers have to be limited with annual culling) using the leather, when the meat is also utilized is seen as sustainable.

Kangaroo populations Of the 48 species of macropods (kangaroos) in Australia, only six abundant species are allowed to be used commercially. The kangaroo industry, which represents a large amount of the commercial meat and leather traders, calls the shooting of kangaroos "commercial kangaroo harvest". They advocate applying under regulated quotas for the limitation of kangaroo populations, because they can overgraze, which can lead to both a loss of biodiversity and conflicts with farmers. As the kangaroos are not farmed, they spend their lives in their natural habitat. The shooting of certain quotas is permitted in six of eight Australian states and some additional areas with large kangaroo populations. According to the kangaroo industry, the limitation of the kangaroo population is the key "to ensure conservation and animal welfare" while "health and safety standards are upheld". Each state government has its own kangaroo management plan to estimate their populations and outline the hunting quotas. Most kangaroos are hunted in the arid grazing rangelands. According to the Australian Department of Agriculture, Water and the Environment, each year about 3 percent of Australia's 50 million kangaroos are used for meat production, which means around 1.5 million animals. The meat of following species is exported as kangaroo meat;

Annual quotas

The National Parks and Wildlife Service South Australia authority must have a detailed management plan for the commercial reduction of the kangaroos, which is approved by the federal conservation department. Detail of the population monitoring and quota-setting controls must be renewed every five years. After the kangaroo population has been estimated, the approved shooting quota is limited to a maximum of 15 to 20 percent of the total population. However usually only about 3 percent of the kangaroos are killed due to the limited demand of the market for kangaroo products. According to the reports published by the government Queensland used only 21 percent of its annual quota and New South Wales just 15 percent in 2014. Only licensed shooters are allowed to kill kangaroos for commercial uses.

Licensing of kangaroo hunters The official name for the "Professional Kangaroo Shooter's Licence" the Government of New South Wales came up with is "professional kangaroo harvester licence". To purchase the tags issued by the authorities, each kangaroo hunter must be licensed as such. Rules for commercial hunters differ from those for private people, who want to obtain a license. In order to obtain a private license, mandatory training has to be attended. The training has to be provided delivered by government-accredited agencies and approved by the Australian Tertiary and Further Education agency in the appropriate State. Hunters are taught about regulatory controls and compliance requirements, the animal welfare controls, and the hygiene controls. They must then pass assessment and adhere to the governmental rules before they are allowed to apply for a license. The 'National code of practice for the humane shooting of kangaroos and wallabies for non-commercial purposes' specifies the minimum high-calibre hunting weapon which are permitted, and requires all animals to be head-shot. Besides that the 20 pages include the direction to kill injured animals immediately and descriptions of how to kill "any dependent young" after a mother was shot (which means hunters are required to examine the pouch as well).

Environmental effects of limiting kangaroo populations

Eastern grey kangaroos reach a very high density in some areas of the Australian Capital Territory. The kangaroos are described as they compete for surface water, damage fencing and farm crops. Shooting kangaroos in rural areas in order to limit their numbers and the damage to farm assets, has not only been common practice for a long time, it continues to be practiced throughout Australia today. Recently concerns have arisen, regarding the impact the overgrazing by large kangaroo populations on other species and ecological communities. Due to overgrazing habitats can change due to soil erosion and a decline in water quality as recent studies have confirmed.

Worked examples

Example 1 — a first encounter with Kangaroo industry

Start with the simplest possible case. Write down what Kangaroo industry claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kangaroo industry before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kangaroo industry ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kangaroo industry

In research
Kangaroo industry appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kangaroo industry in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kangaroo industry is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture in Australia, Hunting in Australia, Kangaroos and wallabies and humans, so understanding it makes those chapters shorter.
In everyday life
Look for Kangaroo industry outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
