The Shark Free Beaches of NSW

The beach is without a doubt the playground for Australians. The formation of national identity is pinned on beach culture. "Australians are islanders and we've come to expect - almost as a kind of birthright, as much as a lifestyle - a certain kind of access to open beaches..." (source) From family holidays (if not in Bali) to national surf events and festivals it is the space to be in. On 2,000 kilometres of New South Wales coast, locals and visitors showcase their beach bodies, swim, surf, play sport and empty their dogs. It appears to be the place of equality. 'Our beach' turf is fiercely defended against 'the other' (Cronulla riots). Its is the only place of summer culture.

The beach as money-making machine
Urban beaches are manicured with fossil fuel and 'renourished' with sand when climate extremes gnaw on the edges. They are artifacts with fences, furniture, nets, signs and flags. Business, surf /events/ competitions - culture, recreation space: gym/sports groups etc monetize this space and depend on it functioning. When the 'cash cow' is closed there is an outcry.

Coastal sprawl and marine urbanisation
Historically the beach turned from a place of work to a (commercialised) leisure ground with the urbanisation of the coast. 85% of people live within 50 kilometres of the coastline today. Coastal sprawl and marine urbanisation seem to concrete the coast from Cairns to Melbourne merging swelling urban centers. The large cities boast degraded biodiversity (and shark nets) and it has become relatively safe to use the beach as if it is a pool. Polluting jet skis, inflatable rescue boats and helicopters are buzzing around swimmers at city beaches for the 'safety of beachgoers'. "Beaches around Sydney, Newcastle and the Central Coast are protected by shark nets, but there is no meshing on beaches in the far north." (source)

 
More people in shark habitats
Population growth (sea change /tree change etc) on the north coast of NSW brings more human beings into the ocean than ever before. "Data from the Australian Shark Attack File indicates the increase in Australian shark attacks coincides with the increasing human population, more people visiting beaches, a rise in the popularity of water-based fitness and recreational activities and people accessing previously isolated coastal areas." (source)
Swimming, diving and some surfing take place in the shallow water. In the deeper water, the ocean is conquered by new adventurous forms of activities going deeper and further in (paddle ski, kayaking, surfing, diving, windsurfing and whale watching in tinnies etc) These plastic-aided adventure activities take place well beyond the flags and far from the mainland.

"Let's not forget the ocean is the domain of the shark." (source)
Various (no take) refuges for marine biodiversity have been established along the coast. Sharks keep the ocean healthy. "Sharks and other ocean predators help protect the ocean's carbon stores by keeping other wildlife in check." (source)

How the presence of sharks and risks are further increased
Heating the ocean through our combustion of biomass seems to benefit the ancient marine predator that has been in the ocean for the last 400 million years. Various human activities, like polluting rivers, throwing fish offal into the beach, fishing or tourism operators using bait to deliberately attract sharks increase the presence of sharks and risks.

 
Shark encounters
Recently there have been 13 shark encounters, including one death off the north coast of NSW this year. (source) Various groups react in fear and want sharks culled or repelled. "Surfers on NSW north coast call for partial cull of sharks after recent months" (source) "Long-time surfers say they are now scared to get into the water." (source) The "far north NSW communities call for shark nets, immediate action to prevent shark attacks." (source)

Extinction - we are working on it...
"Australians in particular have a peculiar, pathological feeling about sharks." (source) Ideally the species should be wiped out (like so many other Australian species) so that man can industrialise the aquatic territory without fear. In the marine habitat, the shark is framed as usual as 'the problem' that needs a 'solution'. A feel-good self-deception, also known as denial could serve to kill this 'monster' and conquer the space for human purposes once and for all. Whatever 'fix' will win, it must be cost effective and be based on technology or fossil fuel. The aim is to 'cleanse' the 'playground' of the competing apex predators (sharks, crocodiles, etc.) so that no people or business interests are harmed. It is known that there is "no “silver bullet” for deterring sharks or stopping attacks." (source). No method is 100% effective, but doing anything would soothe the mind and business as usual could continue. To turn the ocean into a shark-free pool might continue to be a pipe dream.

Risks

The comparative 'tolls' for shark mauling, dog attacks and killings by motor cars makes one wonder, that if by that logic one ought to cull dogs and take these deadly combustion machines off the roads:

• There have been 15 shark-related incidents on the NSW coastline this year, 12 of them on the north coast. (source)
• There were 1,191 dog attacks in the 3rd quarter of 2014/2015 in NSW. (source)
• There have been 260 people killed  in NSW from crashing vehicles so far this year (the injured are not included) (source)

"The day you fail to find sharks cruising your favourite beach is the day you should really start to worry." (source)

Yet Another Traffic Incident - Questions of a Gadfly

Internal combustion powered bikes of all sizes are common in the Bellingen area and NSW. The mostly unlicensed, unregistered and uninsured trail bikes/motorcycles drive on private lands, public roads, forests and National Parks. The roaring noise pollution can be heard over great distances.

Recently a woman walking across a pedestrian crossing at a shopping centre was was hit by a motorcyle. "Five young people were allegedly involved in a 'callous' hit-and-run incident...the CCTV captured the group driving dangerously." Police reported that "at this time of year of course you've got kids on school holidays... sometimes kids are unsupervised" (source) The woman "suffered catastrophic injuries" (very severe head injuries) and her life support was switched off. Andrea Lehane, 34, left behind two small children and a partner.

As with the usual daily car-nage there are a few days of news of the 'mini-motorcycle crash'. With such 'accidents' follows the usual public mourning (on social media) which takes the form of roadside memorials, candlelight vigils, altars, plastic balloons, flower arrangements and the collection of money. After that they all proceed to 'hit the road' of climate extremes again and 'business as usual.'

 
In a car dependent nation, 'accidents' are integral to this mode of transport. The 'road toll' appears to be like a sacrifice to fossil fuel mobility. The daily killing and maiming, the 'hit and run', road-kill and road-rage, driveway 'incidents' and burnouts hog the news. Vehicles are 'out of control' in a dysfunctional system of mobility.

In the above case charges have been laid: " Caleb Jakobsson, 18, has been charged with culpable driving, failing to stop and render assistance, unlicensed driving and using an unregistered motorcycle. "

"A 17-year-old from Seaford has been charged with reckless conduct endangering life, reckless conduct endangering persons, as well as charges for unlicensed riding of an unregistered vehicle..." (source)  A 15-year-old boy was released without charge." (source).

Questions a social gadfly might ask:

Why is it unsafe to walk on a pedestrian crossing in a public area?
Why is it risky to walk?
Why did a human being have to die?

Why were minors out of control?
Why were the children/adult so ‘calous’ to not stop at the pedestrian crossing?
Where was their socialised ‘impulse control’ to refrain and stop once they realised a person was injured?
Will the carers of the offending children change their pedagogic regime?
What did the parents/ carers think where these unlicensed and unregistered trail bikes were going?

Who gave permission for minors to ride these machines?
What sort of 're-creation' (for children) is this?

Why is this suffering and damage bestowed on a household?
Will the damage done to those left behind be 'compensated' by the families of the minors?

Why were unregistered bikes tolerated in the street/ suburb and city/state?
Will people intervene when seeing/hearing vehicles not allowed on roads?

Where was the effective enforcement?
Will the regulator/s take action?
Why is motor racing as 'sport' or 'recreation' modelled as desirable?

Why are all participants and social agents so tolerant of lawbreaking?

Will anything meaningfully change?

The Eels of Bellingen and the Making of Biodiversity Guardians

The scene
The Bellingen River community has just recently allowed the totem of their river, the Bellinger River Snapping Turtle, (Myuchelys georges) to go the way of the dodo. After a mass mortality event it is now listed as a critically endangered species. (PDF)

The event
Soon the 'Bellingen Eel Fishing Championship' will take place. The maltreatment of the endemic Longfin Eels (Anguilla reinhardtii) is 'terrific family fun' promising that 'the kids (will be) amused during the holidays.' (source)

The options
One could instead educate young Australians about the unique fauna and its environment, but the usual 'take, chuck and run' culture is perpetuated.

The eels
Since ancient times, the living fossil has fascinated humans as it has a very mysterious life-cycle. Till today knowledge of freshwater eels and their oceanic migrations and spawning in the tropical Pacific is very limited. Once in their life they travel some 850 km away from their home using smell and magnetism to spawn in unknown locations. During their 6 - 12 month journey they do not feed.

In the EU the Anguilla anguilla is now critically endangered (PDF). After numbers dropped by 99% in 20 years, they have proposed a fishing ban. (source) In NZ the species is overexploited. The Japanese eels are at risk of extinction. The American eel is also in danger of extinction (source). The Taiwanese eel is now perilously close to extinction. (source) It is now uncool to kill and eat the species in many countries.
 
The young guardians
The media abounds with (young) Australians torturing, maiming and killing Australian wildlife and pets. Drive-by shooting of livestock occurs or the latest fashion is killing by bow and arrow. Hate crimes against wildlife are common. Here, here, here, here, here, here, here etc
 
It is possible that individual animal cruelty is just an expression of a national mindset of excelling at the extinction of Australian biodiversity. "Australia is recorded as one of the countries with worst extinction records in the world." (source) Unique animals and plants are allowed to slip into extinction.

On the making of empathy
It has been found that preschool children in NSW "showed callous and unemotional traits such as lacking remorse or empathy for the feelings of other people." The psychopathic traits found could lead to anti social behaviour against their own species (bullying, family violence) or cruelty against any creature.

The undeveloped emotional skills can be acquired by interacting with offspring and teaching "the parents how to be very warm, involved and loving with them to see if that reduces those callous traits over time." (source)

"Respecting other forms of life is not an intrinsic value – it has to be taught, and it has to be learned. While there are certainly exceptions, I am of the opinion that unless you discourage children from that sort of behaviour, it will proliferate into adulthood...Unless we can convince children to respect other species, we can expect to continue failing to elicit much sympathy for the plight of global biodiversity." (source)

The Cerura Moth, The Scott Sisters and Nature Depictions

This hairy moth was hanging out where coastal rainforest trees are allowed to be. Cerura australis (Lepidoptera) is attracted by the perfume of the Flintwood tree (Scolopia braunii). It is the favourite food plant of its larva.

Both moth and tree were depicted by the scientific illustrators and naturalists the Scott sisters, Harriet (1830–1907) and Helena (1832–1910). Their book 'Australian Lepidoptera and their transformations' was published in 1864.

The father and co-author took possession of 2560 acres of prime land on the Hunter River estuary in 1827. Ash Island was seen as a 'paradise for naturalist'. For thousands of years the Worimi and Awabakal people had cultured this tidal wetland into a biodiversity hub. Alexander Walker Scott, an entomologist of the day invited other explorers, like Ludwig Leichhardt to his tropical place and even "offered to clear 10 acres in the district, construct a cottage and establish a vineyard for Leichhardt."(source). With time the usual degradation took place at the hands of settlers: subdividing, clearing, draining, agribusiness and finally industrial use of the landscape. In 1866, AW Scott went bankrupt and sold the Ash Island property. (source)

The young women had many years to depict 'paradise' and functioned as 'lady’ plant collectors to 'male experts' as was common in colonial days. "Their father’s bankruptcy forced the sisters to seek payment for their art and endure the perceived social shame for doing so." (source) Excluded from careers, universities and learned societies they continued to draw and paint Australian animals and wildflowers commercially till the end of their life. The artists were largely forgotten (in the land of pesticides) until there was an exhibition in 2011. (source)

 
One outstanding aspect of these 'amateur' naturalists was, that Harriet and Helena were drawing from live animals. "Most natural history illustrators of the time worked with long-dead, pinned specimens that were faded and lacked colour."(source) They refused the 'pinned' appearance of butterfly and moth cadavers and let them live. They also refused to depict 'the thing' in its decontextualised form. Like Maria Sibylla Merian before them they displayed the mutualistic symbiotic relationships between flora and fauna. The plants and the animals are shown at various stages of their cycles as an educational understanding of living creatures.

The scientific minds and the market demand an encyclopedic knowledge and repository for present and future disposability. Till today 'nature' is classified for the logistics warehouse of man. The 'thing' is still pinned, cut, tagged, frozen in vaults yearning for the self-made catastrophe. The bio-diversity of the ecosystem is reduced to a free service to humanity.

Removing a living organism from its larger environmental context in mind and practice allows for the reduction of life into mere stuff, living beings become mere material for one species' industriousness or the collector's wunderkammer.

The 'thing', once removed from its habitat/ biome can be utilised or exterminated by us and we can remain in proud denial about the basis of our life being pulled from under our (and others) feet.
 
It is also popular to have individual bird sound repositories for example. The 'thing' is without it's home habitat. The soundscape ecologist Bernie Krause: " is interested in a given habitat’s entire soundscape—its “biophony”—(he) finds the single-species paradigm absurd...each living organism in a biome evolves in situ to find its own acoustic niche, based either on frequency or time, so that “their utterances are not buried by other signals.” Thus, each animal sound, plus the sounds of the wind in the trees, or waves on a beach, fit together like pieces of a puzzle to create the kaleidoscopic composition we hear. According to this theory, animals change their sounds when their habitat changes." (source)

A perception and depiction of the whole in situ could contribute to the continuing existence of the web of life.

Today Ash Island is part of Hunter Wetlands National Park.

Car Racing in the Home of the Koala

The koala calls the North Coast forests of NSW its home. Coastal sprawl and deforestation fragment and thin their habitat. The path to the next yummy canopy becomes ever longer and more dangerous. Settlers and their industry demand roads that bulldoze their way through forests 'dripping with koalas'. Many animals are injured and killed by motorists in this process. Their packs of roaming dogs hunt and maul the threatened species. Record-breaking temperatures, "extreme weather events, such as killer heat waves, devastating droughts and intense, flooding rains" unleashed by us will not enhance the life of the koala or any other being.

This weekend it is time again to roar racing cars through Coffs Coast subtropical hinterland. The wonder of 'sustainable' motor racing will take place on forest roads between the Nambucca and the Orara river valleys. Motor 'sport' "is a glorious, lovely thing, all noise and violence and sliding sideways between trees at 100 mph." (source) Dust and noise pollution is generated in abundance.

1400 people donate their free labour to showcase this motor spectacle over four days. Wardens "will use airhorns to scare" the marsupials up the trees. "The numbers of animals that get run over are very low" we are told. (source)

"Population numbers on the East Coast fell by 40% between 1990 and 2010, and in other areas like the Pilliga Forest, the population has crashed by 70% in 10 years." (source)

According to the criteria of the Office of Environment and Heritage, NSW this event does not seem to constitute an 'activity to assist a threatened species'.

Microplastic from Clothing is Accumulating on Shorelines Woldwide

60-85 percent of human-made material found on shorelines consists of micro fibers from clothing. (source)

Plastic clothing has become the norm. From lingerie to outdoor gear, synthetic garments fill shops and wardrobes, cling to bodies and households. Synthetic fabrics (polyester, acrylic, nylon, rayon, acetate, spandex, latex, etc) are convenient and just require a quick spin.

The bright, fashionable colours of the season make the textiles obsolete by the time they leave the shop. Mending is out in a throw-away society. Mountains of old rags go into 'landfill' or end up in smelly second hand shops.

Synthetic and some natural fibers are often pickled in chemicals: toxic dyes, flame retardants, nano -silver and other chemicals in stain-proof textiles and waterproof clothing.



Garments that are washed by hand or machine shed fibers and chemicals/detergents into the water. As there is a paucity of sewerage systems in rural areas like Bellingen and the mid north coast, the effluent drains into the catchment. "Wastewater from domestic washing machines demonstrated that a single garment can produce 1900 fibers per wash." (source)

The shed micro fibers reach the shorelines. They are "micron-scale synthetic fibers, mostly polyester and acrylic, in sediments along beaches the world over." (source)

The invisible contamination of soil, water catchment and marine habitat with microplastic enters the food chain of all living creatures.



Natural fibers, untreated and of organic origin produced and tailored under ethical conditions (no land grab or exploitation) is the right choice to make...

A new parasite in the western long-necked turtle

The western long-necked turtle is found in metropolitan Perth and across south-west WA. When some of the turtles had to be rescued from car accidents,  pet attacks and habitat destruction it was discovered that the oblong turtle (Chelodina colliei) hosts an entirely new species of Eimeria parasite. All 25 turtles had the spore-like oocysts parasites in their faecal samples. None of the turtles displayed clinical signs of coccidiosis—disease caused by parasites including Eimeria collieie.  This is "a first for Australian turtles."

Coccidiosis is commonly found in cattle where it destroys the cells of the intestinal lining.

The interest here is the concern about the Bellinger River turtles ((Emydura macquarii) which have been made extinct through a 'mystery' bug in the Bellinger river environment. The river is flanked by a bovine and livestock milieu.

Sewage discharge and shellfish don't mix. The Bellinger-Kalang rivers.

"One of the more pervasive aspects of European settlement was the pollution of the air and water." (source)

"The indications are that we will not have, inside the Bellinger-Kalang, an oyster industry within the next two years...” (source)

"The Aborigines on the coastal regions feasted on oysters and shell beds can be found in the many kitchen middens along the coast. Some of these middens have been carbon-dated to ten thousand years." (source)

Oyster growers on the NSW Mid North Coast are going to grow Sydney Rock Oysters in land-based tanks now to control water quality. "The Bellinger River was closed for 270 days last year due to heavy rainfall." (source)

Along the Bellinger River catchment and the Kalang River dense settlements sprawl along that are not on any sewer system. The majority of the rural blocks are on an on-site sewage management system (OSMS).

In 2008 sewage bacteria really hit the filter feeding oyster beds. "The NSW Food Authority closed the Kalang River at Urunga in August while a search was made for norovirus, which causes gastroenteritis in humans." (source)

Sewage discharge and shellfish don't mix
"The Bellingen Shire Council says septic systems in the river catchment have been identified as a possible source of the pollution...One of the potential contamination sources are privately operated onsite sewage management systems." (source)



Aquaculture farmers have been waiting for seven years for the Kalang River to reopen to oyster harvesting. "Protracted river testing, analysis and meetings began with riverside septics found to be high on the list of culprits, especially on Newry Island and along Urunga’s Atherton Dr." (source). Additionally the "Urunga sewage treatment plant, holiday cabins, two caravan parks adjacent to the river." were also mentioned as sources of contamination. (source)

After the endemic totem of the river, the Bellinger River turtle has been pushed into extinction, the question of water quality and river health is an acute one for the entire catchment.

The acoustic ecology of native bird extinction and the sound of “cock-a-doodle-doo”

For eons the Laughing Kookaburra has been announcing the break of dawn for eastern Australia. The loud 'koo-koo-koo-koo-koo-kaa-kaa-kaa' is often heard in a chorus. The bird is one of the larger members of the kingfisher family and lives in one place for most of its life. It also mates for life.

The more settlers convert bio-diverse landscapes into mono-culture and populate it with alien species, the ecology changes into an artifact. The soundscape too takes on the characteristic of a noise composition.

Now the highest-ranking rooster has priority to announce the break of dawn. The (overseas) circadian clock of the domesticated fowl often is set off long before dawn. They do not sing in a chorus but in a strict hierarchical pattern. The sound of “cock-a-doodle-doo” echos over the dark valleys. Barking dogs and cars complete the early morning cacophony.

Non-native species and fossil fuel combustion machines constitute the ambient soundscape that announces the break of dawn of more industrial activity. The bird chorus of kookaburras and other common native birds fades as the environmental noise increases.

Deforestation and land clearing robs Kookaburras (and other Australian wildlife) of their homes which they need for nesting, roosting and perching to catch snakes and mice. The generously splashed pesticides poison the insects that the birds eat.

The Park Beach Reserve, Coffs Harbour and Land Care

Click to enlarge

The Park Beach Reserve is unusual for NSW because it has a remaining strip of coastal bush separating it from the 'wanna be a Gold Coast'  high rises on Ocean Parade.  In the age of rising sea levels the Australian habit of building ON the beach and erasing protective vegetation barriers should be a thing of the old days.

The mushrooming tall buildings of Ocean Parade have a slim buffer at the front and back separating them from the road (Hogbin Drive) and the glaring light pollution from a bare sport field framed by large weeds (pines). The busy road and the speeding cars gobble up the green margins. Burnout wrecks set the bush alight and garbage is generously dumped by motorists.

A wide strip of vegetation bordering the road is regularly doused with herbicide, giving the edge of the little forest a brown and dead appearance. In the latest addition to 'land care', it seems that the endemic littoral rainforest species were just hacked to the ground with no apparent reason.

Maybe flat dwellers requested a better view of the noisy road and access to the light glare opposite? All weeds have been left standing. They are working hard on making Coffs Harbour even more ugly.

The Anthropocene Biosphere

Humans are transforming Earth in absolutely unprecedented ways.

A study shows how homo sapiens has radically changed their natural home, planet Earth and has "caused shifts in world ecosystems unprecedented in the last 500 million years." (source)

• Similar to the Great Oxygenation Events 2.3 billion years ago, human impact has produced a new kind of biosphere.
• Intervention in the diversity of life has been the greatest for the past half billion years.
• Our only home, planet Earth is entering a new kind of planetary state

Some of the key changes are:

•         "The homogenisation of species around the world through mass, human-instigated species invasions – nothing on this global scale has happened before

•         One species, Homo sapiens, is now in effect the top predator on land and in the sea, and has commandeered for its use over a quarter of global biological productivity.  There has never been a single species of such reach and power previously

There is growing direction of evolution of other species by Homo sapiens

•         There is growing interaction of the biosphere with the ‘technosphere’ – a concept pioneered by one of the team members, Professor Peter Haff of Duke University - the sum total of all human-made manufactured machines and objects, and the systems that control them" (source)

Afterthoughts:
The global homogenisation of flora and fauna is obvious. People support a world full of poodles and horticultural weeds. They do not appreciate the endemic biodiversity of the place they dwell in. The eradication of bio-diversity is replaced with a monoculture.

Only one species (Homo sapiens) grabs 40% of net primary production

Burning fossil fuels and biomass seems an unstoppable addictive behaviour. We would rather burn to death, than modify our way of life.

Humans dictate the evolution of all other species, also having a go at their own imperfections.

We are constructing a gestell/ artifact that "could persist over geological timescales, an interaction of the biosphere with the technosphere (the global emergent system that includes humans, technological artefacts, and associated social and technological networks)." (source)

This noosphere (mind sphere) or a distributed agency seeks to expand the domination of space as well as planet Earth.

Spaceship Earth is fully in the hands and the code of the human helmsman. While vandalising the cradle of humanity and depriving the rest of life of a habitable planet, man steers for the goal of more and more.
