An abundance of vessels and a new abundance of whales in the "least concern" category set the scene in this inter-species competition. The infant 'Moby Dick' seeks protection in the sheltered bay of the Sydney Basin.
Speculation has it, that it was "abandoned". As the bay of Pittwater is synonymous with yacht racing the Humpback calf turns into a 5 tonne 'problem'. Coaxed out into the deep Pacific, it would have been unclear whether the 5 m mammal was the responsibility of Zoo vets, NSW Parks and Wildlife Service, international agencies or even marine experts. The lone infant returned for the sheltered bay, seeking out what is most plentiful there, namely boats. Voices say that it would "have to be put down", "destroyed" or "euthanized".
Options of feeding it krill outside of captivity are dismissed, despite the 1997 baby whale rescue in the U.S."...The whale was hand-reared back to health before being released into the wild 14 months later. Our veterinarians and our animal care teams immediately went to work to try and save the animal" Such a rescue of a fellow mammal infant would only take a fraction of the budget of dog food or imported seafoods.
Human caused stressors to whales:
- In the anthropocene, megafauna (Megaptera novaeangliae) have been radically depleted due to commercial exploitation. Just recently were they allowed a little bounce back. The bounce comes to a halt with vessel strikes or collisions. Whales are slow to respond to approaching boats, especially those trying to smash race records."A collision with a ship’s propellers can sheer off a whale’s tail, slice them apart, or cause huge contusions." Speed in the marine environment is as deadly as it is on roads. Speed restrictions would reduce the likelihood and severity of vessel collisions. A set-aside Area to be Avoided (ATBA) in the prime migration season would reduce the risks of being separated, severely injured or killed on the annual trek.
- Noise : The roaring of the industrialised marine commerce or 'sport' is interfering with whale communication. The noise can cut off vocal, behavioral and physiological responses between a whale and its offspring. To get entangled in our debris is a further hindrance.
- Human-caused climate change deprives whales of food. Krill populations decline in rising temperatures, which " will require migratory whales like this Humpback whale to swim further for less food."
- Mining the oceans with invasive, noisy and polluting practices "Oil and gas exploration expose whales to noise pollution, oil spills, chemical pollution, vessel collisions and entanglement with or ingestion of marine debris."
Share the habitat!
- Effectively protect these highly migratory marine mammals in their habitat.
- Impose (seasonal) speed restrictions in areas frequented by whales and other protected fauna.
- Create a protected crucial habitat as an Area to be Avoided (ATBA).
- Divert some of the attention and budget bestowed on pets to unique marine mammal protection.
- Reconsider mining and dredging Megaprojects on the coastline

More on disruptive noise in the oceans for marine mammals:
"Ocean Noise: Turn it Down", pdf
Noise from vessels, increased seismic surveys for oil and gas, off-shore construction and recreation, and a new generation of military sonars can interfere with whales. "The United Nations Environment Programme's Convention on Migratory Species conference in Rome, are urging governments and industry to adopt quieter engines for ships, tighter rules on the use of seismic surveys, and new, less intrusive sonar technologies by navies...Ship noise in the Pacific Ocean has doubled every decade over the past 40 years and the global shipping fleet is expected to double in size by 2025, after doubling between 1965 and 2003.There is now evidence linking loud underwater noises with some major strandings of marine mammals.
By 2050 the chemistry of seawater could increase in acidity by 0.3 pH units... this change in ocean acidity would allow sounds to travel up to 70 percent farther underwater." Environmental News Service 031208

Imagine a baby and its carer get separated at a busy freeway node – impossible to find each other again, the weakened child mistakes a parked SUV for its mother and attempts, in vain, to get nourishment. Helpful creatures manoeuvre it out into the 'wide and open spaces' where it might be hopefully reunited with its mother.
Humpback calf lost in Pittwater
Such is the story (sad video) of a very young humpback calf found in isolation from its mother in busy Pittwater bay, north of Sydney. These slow-moving marine mammals, with their offspring in tow are on age-old journeys across the globe. For eons they have traversed their same marine territories. First, they were massacred by Australian whalers, now the whale watching industry has to lure the tourist dollar. Their habitat has also changed rapidly: The sheltered bays and the open ocean are more like the terrestial world's car-parks, oozing repair workshops, endless wider roads to shoot private mobility capsules along. The largest obstacle to their efficient flow are soft-bodied, slow-moving organisms, known as pedestrians and wildlife.
Aqua motoring in the Pittwater region (or anywhere else) operates according to the same mind-set. One look at Google Maps reveals the area is criss-crossed with boats racing and most of the shores are more akin to "car-parks". Industrialising and commercialising the water-bodies and the marine habitat brings about many "externalities" for the environment. Eutrophication from combustion powered boats, from sprawling sub-urbs and the associated 'shared debris' turns the beautiful Pacific and its bays progressively into dead zones. Not just for seasonal visiting whales - but for all living creatures. If they do not get entangled by anthropogenic debris or get infected, human business also robs them of their habitat, the open ocean.
Mega fauna is in the way
The intensification is a take-over by the terrestial mammals of the habitat of the whales, that do not have any other habitat to survive in. On the open oceans, whales are simply in the way of busy shipping lanes and other boats.. "In places where marine traffic is heavy, vessels fast and whale numbers expanding, violent encounters are increasingly common.” As on our roads - many cetacean and other marine animals are being maimed or killed by the 'collisions'. The wildlife of the oceans is becoming a "a hazard to sea craft" in their own habitat. In some areas the International Maritime Organization has designated an "Area to Be Avoided" for container ships to avoid killing them.
Even when not assaulted by aqua motoring the noise and vibration caused by the human racket will diminish their life or even kill them: "The throb of mighty engines and the thrash of propellers as 60,000 huge vessels plough the world’s sea lanes; the hammer of diesels and scream of outboards as 4 million fishing boats and more than 10 million ferries and pleasure craft surge to and fro; the thump and ping of military and fishing sonars; the deafening crash of seismic ships seeking oil and gas; the blare of acoustic harassment devices; the grinding of drills and dredges; the low-frequency growl of scientific experiments designed to monitor global warming."
Could it be, that in such a hostile habitat the whale and its calf became seperated though a degraded habitat and many missiles interjecting their journey?

Today's news of the construction of a 16-storey drilling platform off Kurnell, Cape Solander assured us that "The six-month operation will..not have any impact on migrating whales. I have every confidence the whales will swim around it..There will be no impact on the residents of Kurnell"
Will the whales still make it past Manly?
Could Manly become another 'Kurnell'?
Once water conservation is off the agenda, the high cost and high energy option of desalination plants appears to be the only way to continue unsustainable practices on the driest continent. The environmental costs, apart from turning the sea/shore into an industrial zone (image) are carried by the wildlife and its biome.
The following reading list is highly recommended on topics that will not disappear in our life-time:
Desalination projects & transparency:
Phil Dickie of melaleuca media investigatives the options of desalination plants in "Making Water - Desalination option or distraction for a thirsty word" 0707 for WWF’s Global Freshwater Programme. "The first global survey of desalination from a non-industry perspective" (pdf) Regarding Australia:
"All of the areas where seawater desalination is rapidly assuming a more prominent water supply role had more cost effective and less potentially environmentally damaging alternatives available. This is particularly true of demand management, water conservation and water efficiency measures, where many of even the more advanced economies such as Australia do not uniformly require easily achievable water and energy efficiency standards in new buildings."Megaprojects & Transparency:
Bent Flyvbjerg, on megaprojects, Chapter 1 of his book Megaprojects and Risk: An anatomy of Ambition, by Bent Flyvbjerg, Nils Bruzelius, and Werner Rothengatter (Cambridge University Press, 2003). Some of his interests are transparency in policy planning and strategic misrepresentation wrt megaprojects.

As reported before: Extended time, flat on the back, lacking sensual interaction is a form of deprivation for developing human beings. The average child might now spend extended time in a 'convenient' capsule. “Parents are not picking up their infants when the infants are awake... you get a stroller and car seat combo. And because the car seat snaps in and out of the stroller and the vehicle, often the baby simply stays put after reaching a destination.” These “mobility” gadgets might appear as a convenient “life saver” for parents in their 4x4s/cars.
For the capsule-bound and interaction-deprived infant it often means:
- motor delays
- “.. developmental, cognitive, and organizational skills delays, eye-tracking problems, and behavioral issues”
- the flattening of the baby's skull, occurs “in infants who spend too much time on their backs while awake.”
- This syndrome is also termed 'Flat-head syndrome' or plagiocephaly.
“In recent years, craniofacial centers and primary care providers reported a dramatic increase of up to 600 percent in referrals for misshapen heads.” Various service industries and products (eg cranial helmets) have sprung up, promising 'corrections' of the unintentional cranial modification. The hindered development of the neurological network will most likely be a life-long handicap.
Experts are urging “parents and caregivers to ensure that babies get enough "tummy time" throughout the day while they are awake and supervised”. Quality interaction is needed to produce a human being through interactive behaviour. "Increasing the amount of time your baby lies on his or her tummy promotes muscle development in the neck and shoulders; helps prevent tight neck muscles and the development of flat areas on the back of the baby's head; and helps build the muscles baby needs to roll, sit and crawl" "It's important to get our infants out of devices that constrain mobility and onto their tummies so they can focus on neck muscle balance as they interact with their caregivers," “We're going to have to be more actively involved with them” - beyond a 'rotate daily'.
Have a look at the Manly poodle & pram parade, check out the adults' active interaction with their mobile or the dog/s. In the eateries, do the kids stare at the wall, while the grown-ups are interacting with each other and the environment?
Some cafes/eateries in Europe have introduced pram parking at the front door, fold it up and into a slot. The baby/or multiples are then carried or walked to the area where the group wishes to engage with one another.
Experts urge parents/caregivers to facilitate mobility for their infants and not constrain mobility. Craniofacial deformities and a deficient neurological network can be prevented. 'Activities to Help You Position, Carry, Hold and Play with Your Baby' advises on basic interaction.
