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)

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...

Sponges at Diggers Beach

Coral

Diggers Beach is part of the The Solitary Islands Marine Park Coastal Walk (pdf). A suburban beach where people come to surf, swim, jog, sun-bake and empty their dogs (illegally). Rarely does anyone look at the flora and fauna at the beach. The beach serves as a backdrop for their activities.

At high tide and during storms sponges are dislodged from their garden communities and end up amongst rocks, seaweed and shells at the beach. If one is observant, these ancient multi cellular organisms (Porifera) can be found in a multitude of colours and structures. They cling to the floor of the ocean and allow nutrient-containing water to circulate through their pores and channels. 

"Like all temperate life forms in the waters of southern Australia the habitat forming invertebrates in sponge gardens rely on clean water and sufficient nutrients and food particles to survive. Because many of the animals are permanently attached to the rock and unable to move around, they cannot go in search of food or flee from harm." (source)

They emerged 700 million years ago, when the oceans contained little oxygen. “The effects we predict suggest that the first animals, far from being a passive response to rising atmospheric oxygen, were the active agents that oxygenated the ocean around 600 million years ago....They created a world in which more complex animals could evolve, including our very distant ancestors.” (source)
