England fells more trees than it plants and government must keep to its targets to evade deforestation, say forestry groups

Every year Brazil, Congo and other developing countries are lambasted by environmentalists and western politicians for deforestation at a time when trees are needed to counter climate change and prevent flooding.

Now two prestigious organisations are warning that England may have tipped into deforestation, with more trees being cut down than planted for the first time in possibly 40 years.

Claxton, Norfolk They rose and fell, swaying as if one organism were breathing slowly, and as they approached they never made sound

I saw the goose skein as a tentative line in a southern blue sky and, since it was arrowed straight towards me, I rested arms and binoculars on a gate to ease the muscle ache.

One, two minutes must have passed as the skein slowly grew, before it occurred to me that large birds in flight never rush. The wing beats are steady, solemn, self-reliant. I remember once in eastern Turkey watching a line of flamingos like this. There is an almost identical length of neck and leg fore and aft of those pink flamingo wings and, such was their lack of progress, it was a good five minutes before I could even work out in which direction they flew.

Recent calls for a ban on legal traditional hunting of dugongs and marine turtles imply that hunting is the main threat to these iconic species in Australia. The science indicates otherwise.

While more is being done to address traditional hunting than any of the other impacts, the main threats to their survival often pass unnoticed.

The real threat to sea turtles

The draft Recovery Plan for Marine Turtles in Australia evaluated 20 threats to the 22 populations of Australia’s six species of marine turtle. Climate change and marine debris, particularly “ghost nets” lost or abandoned by fishers, are the greatest risks for most stocks.

Indigenous use is considered to be a high risk for three populations: Gulf of Carpentaria green turtles, Arafura Sea flatback turtles and north-eastern Arnhemland hawksbill turtles.

However, in each of these cases it is the egg harvest, not hunting, that causes concern. International commercial fishing is also a high risk for the hawksbill turtle, whose future remains uncertain. Traditional hunting of marine turtles in Australia is limited to green turtles.

Is hunting a threat?

The Torres Strait supports the largest dugong population in the world and a globally significant population of green turtles. Archaeological research shows that Torres Strait Islanders have been harvesting these species for more than 4,000 years and the dugong harvest has been substantial for several centuries.

Our research shows that the Torres Strait dugong population has been stable since we started monitoring 30 years ago and that the harvest of both species is sustainable.

The situation for dugongs is very different in the waters of the Great Barrier Reef south of Cooktown. The Great Barrier Reef Outlook Report classifies the condition of the dugong population in this region as poor.

Modelling indicates that the southern Great Barrier Reef stock of the green turtle, which live and breed south of Cooktown, is increasing.

Nonetheless, both green turtles and dugongs died in record numbers in the year after the extreme floods and cyclones of the summer of 2010-11. Dugongs stopped breeding in the Great Barrier Reef region south of Cooktown.

Thankfully, our current aerial survey indicates that dugong calving has resumed as inshore seagrass habitats recover. There is no evidence that the 2011 losses significantly affected green turtle numbers.

Working together

Traditional owners are the first managers of our coastal waters, with cultural practices extending back thousands of years. They have the most to lose from any loss of turtles and dugongs. It is therefore in their best interests, and the government’s best interest, to work in partnership to protect and sustainably manage these species.

Longstanding tensions between traditional owners and tourist operators are behind much of the opposition to traditional hunting in the Cairns area. Some of these tensions have been relieved by the Gunggandji Traditional Use of Marine Resources Agreement signed in June 2016.

Under this agreement, the traditional owners decided to cease hunting turtles and dugongs in the waters surrounding Green Island, Michaelmas Cay and Fitzroy Island.

The Gunggandji agreement is the seventh to be signed between the Great Barrier Reef Marine Park Authority and traditional owners. In addition, there are two Indigenous land use agreements that address hunting issues in the Great Barrier Reef.

In the Torres Strait, dugong and turtle hunting is managed through 14 (soon to be 15) management plans. There are similar agreements with traditional owners and management agencies in other regions in northern Australia.

Indigenous rangers are crucial to implementing all these agreements in collaboration with management agencies and research institutions. Rangers deliver the practical, on-the-ground arrangements to conserve these species in their Sea Country.

The Great Barrier Reef Marine Park Authority has implemented an Indigenous Compliance Program that authorises trained Indigenous rangers to respond to suspicious and illegal activities that they encounter as part of their work.

Indigenous rangers also remove marine debris from remote beaches. The community-based organisation GhostNets Australia has worked with 31 coastal Indigenous communities to protect over 3,000km of northern Australia’s saltwater country from ghost nets. These community projects have been instrumental in rescuing turtles, clearing ghost nets off beaches and identifying key areas to aid management agencies to better understand the impact.

Traditional owners from the Torres Strait and the northern Great Barrier Reef also play a valuable role in intervention works at Raine Island, one of the world’s most significant green turtle rookeries. This includes rescuing stranded turtles, using fences to stop turtles from falling over cliffs, and altering beach profiles.

What about welfare?

Traditional hunting raises animal welfare issues. The turtle and dugong management plans developed by the Torres Strait communities explicitly address animal welfare. The Torres Strait Regional Authority has been working with a marine mammal veterinarian and traditional owners to develop additional methods of killing turtles humanely.

Indigenous hunters who breach state and territory animal welfare laws can be prosecuted. But more widespread animal welfare problems, not associated with hunting, are largely hidden and ignored. The Queensland Strand Net Program reported that 879 turtles died of their wounds from vessel strike between 2000 and 2011.

Other serious animal welfare issues are associated with animals drowning in nets and being caught in and ingesting marine debris. In addition, the potential impact of emerging threats like underwater noise pollution and water quality remain as substantial knowledge gaps. These matters tend not to make the headlines.

Australian waters are home to some of the world’s largest populations of marine turtles and dugongs. A comprehensive and balanced approach to their conservation and management is required to enable our grandchildren and their children to enjoy these amazing animals.

The regular use of Caesarean sections is having an impact on human evolution, say scientists.

OPEC’s recent decision to cut oil production for the first time in eight years marked the return of the oil cartel’s favourite tactic: squeeze supply in a bid to jack up the price.

Of course, this is nothing new. In 1851, during the Pennsylvania oil rush, the Oil Creek Association helped to push the price of oil up from 10 US cents a barrel to US$4.

OPEC can only dream of having the power to move prices by 4,000%. The reality is that its power to move prices at all is waning rapidly, as factors move beyond the bloc’s control.

It’s worth noting what happened to the oil drillers of Pennsylvania after they installed a floor under their high oil prices. Investors shifted their focus elsewhere, looking to Russia, Texas and eventually the Middle East. Precisely the same thing is happening to OPEC, particularly through the advent of the US shale oil industry. And this time it’s happening not in the golden age of oil but in an era when market conditions for polluting fuels are much tougher.

In 2008, when oil prices were high, Goldman Sachs predicted that oil would hit US$200 a barrel. But they are financial wizards, not historians. It has been 75% less for most of the period since.

Over the decades we have also grown used to hearing predictions that there are “only 30 years of oil left at current production rates”. (The horizon never seems to move any closer or further away.)

But bear in mind that oil reserves are a function of technology and price. When prices rise and technologies improve, more oil becomes economically viable to extract, effectively increasing the world’s oil reserves. As prices fall, these reserves effectively cease to exist until prices rebound or technology gets cheaper.

So, in one sense, the oil game hasn’t changed. OPEC needs high prices to justify extracting the oil. But bigger factors are now at play, which makes it harder for OPEC to squeeze supply as effectively as it once did.

What has changed?

OPEC was at its most powerful when the United States, the world’s largest oil consumer, relied on OPEC member states to meet its oil needs. Since the US shale boom increased US energy independence, OPEC can no longer threaten supply as it did during the 1970s. Now it simply risks squeezing itself out of the market.

It’s not just the US domestic market that has grown. If OPEC restricts supply, Canada can increase oil production from tar sands, and Brazil can bring on more deep-water oil production.

All of this challenges the perception that there is a shortage of oil, although more sophisticated peak-oil followers have shown that cheap oil from conventional sources did indeed peak in 2007, prompting the most recent big surge in oil prices.

In a bid to maintain its influence on supply and therefore prices, OPEC has turned to Russia, the world’s largest state-controlled oil producer, which has agreed to cut production in tandem with OPEC nations.

But even this will not be enough to keep pace with the changes wrought by new markets, new technologies and energy efficiency. Two years ago we wrote that OPEC had lost its power and, despite the latest move, we don’t see much to indicate that it has returned.

The knock-on effects

The fundamentals of the oil industry haven’t changed with this latest deal. In Australia the effect will be a roughly 5% increase in the oil price, and a larger increase in the price of petrol (perhaps up to 10%), as distributors and retailers take advantage.

Aside from the small effect on Australian consumers, this announcement will probably be helpful to Australian oil companies, giving them some good news to tell shareholders and employees.

But before boardrooms get too excited, it is worth noting that oil is also suffering a demand problem. All developed nations have now begun to decouple economic growth from fossil fuels. For oil, the chief threat is one of being replaced by electric public transport and electric or hybrid cars.

Oil’s murky future

Oil’s future suffers from another problem: it’s not good for your health. An announcement that will have a more powerful effect on the oil price, but which received much less media attention, came in 2012 when the International Agency for Research on Cancer (IARC) updated its classification of diesel engine exhaust from “probably carcinogenic to humans” (Group 2A) to “carcinogenic to humans” (Group 1). Petrol exhaust is listed as probably carcinogenic.

Health impacts are a large driver for moving away from fossil fuels – even for those who don’t accept the predicted climate impacts. With the fundamental shift towards fuel efficiency and electric vehicles, the Volkswagen emissions scandal and the awareness that petrol and diesel cause cancer, respiratory disease and lower birth weights in babies with mothers living near major roads, the trend for oil consumption is downward.

So the drivers for change are as they have always been – demand and technology are behind the wheel, not OPEC making “important” announcements. Look for a small, short-lived increase in your local fuel price, but remember that if your tank of fuel goes up by 10c a litre, most of that isn’t down to OPEC. It’s mainly retailers looking for a bigger Christmas bonus.

An expert on Australian native species says birds can have empathy, grieve after the death of a partner and form long-term friendships

It is generally quite well-known that kookaburras live in family groups: a bonded male and female, plus a retainer of their offspring. Numbers matter in kookaburra society because a neighbouring tribe may have its eye firmly on the expansion of territory – and may invade a smaller group.

This means the injury and eventual death of one bird – most crucially of one of the parent birds – can have disastrous effects for the remaining group. They could be evicted from their home, which is likely to lead to their death.

Poll commissioned by the Australia Institute finds 41% oppose funding the link between the coalmine and port in north Queensland while 33% support it

More Australians oppose the idea of funding infrastructure for the Carmichael coalmine than support it, although the reverse is true in Queensland, a new poll has found.

The Research Now poll commissioned by the Australia Institute, released on Tuesday, found that 41% opposed funding construction of infrastructure to help the Adani coalmine, compared with 26% who supported it and 33% who were undecided.
