Just as President John F. Kennedy famously implored Americans to ask what they might do for their country rather than vice versa, the New South Wales government’s decision to ban greyhound racing from July next year suggests an approach that asks not what animals can do for us, but what we can do for them.

Nor is NSW the only place looking at dog racing in this way. In the 55 years since JFK’s speech, 40 US states have banned greyhound racing, leaving only 19 dog tracks in six states still operating.

The principal reason for the NSW government’s decision is the high “wastage rate”. According to the special inquiry into the NSW industry, 50-70% of all greyhounds raised for racing are killed simply because they are too slow, meaning that at least half of the almost 98,000 dogs bred for racing over the past 12 years have been killed.

Reforming the industry was considered possible, but difficult, in relation to the live baiting scandal that engulfed Victorian racing in 2015. But the wastage of dogs that are too slow has become an integral part of the business model, rather than a rogue practice, and as such is much harder to tackle.

Similar problems exist in the racehorse industry, where the wastage rate is close to 40%. But the financial and political implications of a similar ban on horseracing are far more profound. There have already been suggestions of a class factor at play here, with the sport of kings protected while the “battlers' sport” is banned.

Protecting ‘useless’ animals

Protection for animals that have outlived their useful purpose for humans is relatively rare in Western societies, but in Eastern religions it often features prominently. In India, cows that are too old to give milk are retired to shelters, where the public donate food and money to keep them in good health until they die. This principle is firmly embedded in the Hindu religion.

In contrast, the Christian and Muslim traditions hold that animals have been put on Earth solely for our benefit. For most scientists and philosophers this is a convenient interpretation of the scriptures but biologically absurd, especially when we consider the question of the killing of those that don’t suit our purpose or match up to arbitrarily defined standards.

Some will argue that (humanely) killing an animal does not affect its welfare, but most acknowledge that we have a moral imperative to provide animals with a life that is valued and sufficiently long to be worth living.

Western society is beginning to wake up to the massive wastage in its dairy industry, with male (bobby) calves routinely slaughtered at just a few days of age, and cows that rarely last more than two or three lactations in the herd being killed at about 5 years of age, when their natural lifespan is 25.

There are the rudiments of protection systems in Western society, for some animals at least. Regarded by the industry as “spent hens”, chickens are routinely condemned to an early death after just one season’s laying because they will be less productive in their second year. But charities are beginning to offer opportunities for members of the public to give homes to these hens. Similarly, the Donkey Sanctuary in the UK offers retirement to weary donkeys.

For many the recognition in Western society that animals are not just a commodity is too little, too late. The animal industries are intensifying at a rate never experienced before in response to growing demand, particularly in Asia. The financial pressure on greyhound trainers to increase their dogs’ speed to win more prize money is so great that they often don’t consider the ethics of what they are doing. Illegalising a cruel business is the only answer.

And how will the greyhounds be affected by this decision? There are concerns that the ban will lead to more deaths as trainers dump their obsolete dogs. Is rehoming an alternative to wastage? The extensive selection of the greyhound for speed makes them less than ideal as pets, and it seems unlikely that new homes can be found for all of NSW’s greyhounds.

Advocates will argue that the dogs love the sport. Admittedly there is something in dogs that makes them chase objects that run in front of them, and many dogs will do it until they are exhausted. It’s in their genetic makeup, as over the millennia of evolution those that could do this would have had an advantage. But it is the associated treatment of the dogs as commodities that makes this sport unacceptable in today’s society.

Beyond reform?

The other reason for the NSW government’s decision is that the industry was deemed to be inherently corrupt and beyond reform, as detailed by Justice Michael McHugh’s report on the industry. This is a sad reflection of how the government/industry partnership model of managing our animal industries has failed to inspire confidence.

The ACT has also announced a ban, although other states seem unlikely to follow suit, citing the profit generated by the industry or the high costs of compensating those involved.

The Victorian government believes it can reform its industry in the wake of the live baiting scandal, but the Australian federal government has repeatedly claimed to be able to do this with livestock export and still the exposés of cruelty keep coming.

Asking what we can do for the greyhounds that have been exploited in this way is just the first step in repairing a damaged sense of trust that man’s best friend so faithfully placed in us.

Kelp forests along some 100km of Western Australia’s coast have been wiped out, and many more areas damaged, by a marine heatwave that struck the area in 2011.

The heatwave, which featured ocean temperatures more than 2℃ above normal and persisted for more than 10 weeks, ushered in an abrupt change in marine plant life along a section of Australia’s Great Southern Reef, with kelp disappearing to be replaced by tropical species.

As we and our international colleagues report in the journal Science, five years on from the heatwave, these kelp forests show no signs of recovery.

Instead, fish, seaweed and invertebrate communities from these formerly temperate kelp forests are being replaced by subtropical and tropical reef communities. Tropical fish species are now intensely grazing the reef, preventing the kelp forests from recovering.

Assessing the damage

We and our team surveyed reefs along 2,000km of coastline from Cape Leeuwin, south of Perth, to Ningaloo Reef between 2001 and 2015.

Up until 2011, temperate reefs were clearly defined by the distribution of kelp forests which formed dense, highly productive forests as far north as Kalbarri in WA’s Mid West.

Since 2011, the boundary between these temperate reefs of southern WA and the more tropical reefs (including Ningaloo) to the north has become less clear-cut. Instead, the sharp divide has been replaced by an intermediate region of turf-dominated reefs.

This has implications for the Great Southern Reef (GSR), which extends more than 8,000km around the southern half of Australia from the southern half of WA all the way to southern Queensland – a coastline that is home to around 70% of Australians.

Kelp forests are the GSR’s “biological engine”, feeding a globally unique collection of temperate marine species, not to mention supporting some of the most valuable fisheries in Australia and underpinning reef tourism worth more than A$10 billion a year.

But our research shows that on the GSR’s western side, kelp forests are being pushed towards Australia’s southern edge, where continued warming puts them at risk of losses across thousands of kilometres of coastline because there is no more southerly habitat to which they can retreat.

While the 2011 marine heatwave affected some 1,000km of Western Australia’s temperate coastline, it was a stretch of roughly 100km extending south of Kalbarri on the state’s Mid West coast that was most severely affected.

In this area alone an estimated 385 square km of kelp forest have been completely wiped out.

Further south, from Geraldton to Cape Leeuwin, the extent of kelp loss was less severe, despite an estimated total area of 960 square km having been lost in the region.

Northern regions towards Kalbarri were more severely affected because these kelp forests were closer to their limit, and also because this area is closer to the tropical regions like Ningaloo Reef, meaning that tropical species could more easily move in.

The problem was exacerbated by the southward-flowing Leeuwin Current, which helps tropical species move south while making it harder for temperate species to move north and recolonise the affected areas of the GSR.

The combination of these physical and ecological processes set within a background warming rate roughly twice the global average, compounds the challenges faced by kelp forests in the region.

The plight of WA’s kelp forests provides a strong warning of what the future might hold for Australia’s temperate marine environment, and the many services it provides to Australians.

Antarctica’s early history was marked by national rivalries – think of Britain and Norway racing to the South Pole in 1911. But since the signing of the Antarctic Treaty in 1959, collaboration has become more important than competition. And the relationship between Australia – Antarctica’s biggest territorial claimant – and China, the emerging superpower, is among the most crucial of all.

One of Australia’s key aims, as set out in its Antarctic Strategy and 20 Year Action Plan, is to strengthen the existing Antarctic Treaty system, by “building and maintaining strong and effective relationships with other Antarctic Treaty nations through international engagement”.

As Australia’s largest trading partner and a significant player in Antarctica, China is a crucial nation with which to engage if Australia is to meet its objectives. This raises the question of how the two countries might fruitfully cooperate in Antarctica over the next 20 years.

Existing ties

China began its first scientific expedition to Antarctica in 1984. It now has four Antarctic bases, two on Australian-claimed territory.

Australia and China’s Antarctic ties have thus been evolving for more than three decades, with a focus on science, logistics and operations. Bilateral relations seem to have strengthened in recent years.

In 2014, President Xi Jinping visited Hobart and signed a memorandum of understanding with Australia to collaborate in Antarctica and the Southern Ocean.

Last year, Australia’s Antarctic Climate and Ecosystems Cooperative Research Centre signed an agreement with its Chinese counterpart, the National Marine Environmental Forecasting Centre, to develop new forecasting methods to aid the challenging task of navigating Antarctic sea ice.

February 2016 saw the inaugural meeting of the China-Australia Joint Committee on Antarctic and Southern Ocean Collaboration, which arose from the 2014 agreement.

But it has not all been smooth sailing. China has strongly opposed Australia’s proposal to establish a network of marine protected areas off East Antarctica.

Australia is also concerned about China’s presence in Antarctica. For example, a news article at the time of Xi’s 2014 visit suggested that “China may eventually try to overthrow the Antarctic Treaty system underpinning Australia’s claim to 43% of the frozen continent”, while questions have been asked about the scope of China’s mining ambitions on the frozen continent.

Potential future collaborations

There are several reasons, however, to expect that China and Australia can put aside their diplomatic differences in pursuit of Antarctic science.

First, it seems more likely that China will continue to endorse the Antarctic Treaty than to undermine it. As a rising power, China has growing interests in the Southern Ocean but it has no territorial claim in Antarctica. It would certainly not be at the front of the queue in the ensuing land grab if the treaty were to end.

Realistically, China should therefore continue to support the treaty, under which the seven existing national claims (plus any prospective claim by the United States, which has a research base at the South Pole) are suspended.

This logic is backed up by China’s behaviour with regard to the even more politically fraught North Pole. By becoming an observer of the Arctic Council, China has opted to embrace rather than challenge the current Arctic regime, despite the jockeying among Arctic nations over territorial rights.

Second, to maintain Australia’s leadership and excellence in Antarctic science, it will need to collaborate with industry and other nations. As an economic powerhouse, China has both the funding and the technology to deliver things like icebreaker ships, a well as a keen interest in Antarctica, which should extend to long-term scientific collaborations.

Third, Australia wants to maintain its leadership in environmental stewardship of Antarctica. One current hurdle seems to be China’s opposition to Australia, France and the European Union over the planned marine protected areas off East Antarctica. As the world’s largest fishing nation, China’s reluctance to support “no-take zones” is hardly surprising.

Nevertheless, this issue could potentially be converted from obstacle to opportunity, perhaps by Australia inviting Chinese scientists to conduct joint scientific research in these areas of the Southern Ocean. This would not only improve understanding of unknown marine ecosystems, but would also be a useful way for Australia to exert diplomatic “soft power”.

Finally, Australia has its own economic interests in Antarctica, such as sustainable fishing and tourism. Meanwhile, ever greater numbers of Chinese tourists are venturing abroad, with visits to Australia passing the 1 million mark last year. With Antarctica now also on the radar for China’s richer tourists, Australia could not only benefit economically but must also work closely with China to develop regulations that prevent this nascent industry from damaging the Antarctic environment.

All of this means we can reasonably expect Australian-Chinese ties to grow ever closer over the next two decades – even in the world’s remotest place.

The plain fact is that we are not going to get proper funding for social care until we see providers either exiting the market, or refusing unsustainable contracts (Letters, 7 July). This must be a warning to local authorities and the government that once this sector starts to fail it will also bring the NHS to breaking point because nobody can be discharged. At which point we hope the minister of state might finally get it into his head that social care is an essential part of the system.

About 90% of forests off the western coast were wiped out between 2011 to 2013, posing a threat to biodiversity and the marine economy, say scientists

A hundred kilometres of kelp forests off the western coast of Australia were wiped out by a marine heatwave between 2010 and 2013, a new study has revealed.

About 90% of the forests that make up the north-western tip of the Great Southern Reef disappeared over the period, replaced by seaweed turfs, corals, and coral fish usually found in tropical and subtropical waters.
