The refugee crisis that dominated the news in 2015 and 2016 consisted primarily of a sharp rise in the number of people coming to Europe to claim asylum. Arrivals have now dropped, and governments have cracked down on the movement of undocumented migrants within the EU; many thousands are stuck in reception centres or camps in southern Europe, while others try to make new lives in the places they have settled.
But to see the crisis as an event that began in 2015 and ended the following year is a mistake, because it obscures the fact that the underlying causes have not changed. To see it in those terms only gives the impression of a hitherto unsullied Europe, visited by hordes of foreigners it has little to do with. This is misleading. The disaster of recent years has as much to do with immigration policies drawn up in European capitals as it does with events outside the continent, and the crisis also consists of overreaction and panic, fuelled by a series of misconceptions about who the migrants are, why they come, and what it means for Europe.
The European Union has perhaps the world’s most complex system to deter unwanted migrants. Since the 1990s, as borders have come down within Europe, giving most EU citizens free movement and passport-free travel, its external frontier has become increasingly militarised. Amnesty International estimates that, between 2007-2013, before the crisis, the EU spent almost €2bn on fences, surveillance systems and patrols on land or at sea.
In theory, refugees – who have the right to cross borders in search of asylum under international law – should be exempt from these controls. But in reality, the EU has tried to prevent asylum seekers from reaching its territory wherever possible: by closing down legal routes, such as the ability to claim asylum at overseas embassies; by introducing penalties for transport companies that allow people to travel into the EU without the correct documents; and by signing treaties with its neighbours so they control migration on the EU’s behalf. And within the EU, an agreement called the Dublin regulation forces asylum seekers to apply in whatever country they reach first. [Continue reading…]
Five myths about the refugee crisis
How music can fight prejudice
The outpouring of hostility toward immigrants and refugees has reminded us that ethnocentrism remains a fact of life in both Europe and the United States. Combating it will require teaching a new generation to view members of different cultures as potential friends rather than threatening outsiders. But what mode of communication has the power to stimulate such a shift?
New research from Portugal suggests the answer may be music.
It reports schoolchildren around age 11 who learned about the music and culture of a faraway land expressed warmer feelings toward immigrants from that country than those who did not. What’s more, those positive emotions were still evident three months after this exposure to the foreign culture.
“Music can inspire people to travel to other emotional worlds,” writes a research team led by psychologist Felix Neto of the University of Porto. Their work suggests songs can serve as an emotional bridge between cultures, revealing feelings that are common to both. [Continue reading…]
Humanity is a tiny fraction of life on Earth but has destroyed over 80% of wild mammals and half of plants
Humankind is revealed as simultaneously insignificant and utterly dominant in the grand scheme of life on Earth by a groundbreaking new assessment of all life on the planet.
The world’s 7.6 billion people represent just 0.01% of all living things, according to the study. Yet since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds.
The new work is the first comprehensive estimate of the weight of every class of living creature and overturns some long-held assumptions. Bacteria are indeed a major life form – 13% of everything – but plants overshadow everything, representing 82% of all living matter. All other creatures, from insects to fungi, to fish and animals, make up just 5% of the world’s biomass.
Another surprise is that the teeming life revealed in the oceans by the recent BBC television series Blue Planet II turns out to represent just 1% of all biomass. The vast majority of life is land-based and a large chunk – an eighth – is bacteria buried deep below the surface.
“I was shocked to find there wasn’t already a comprehensive, holistic estimate of all the different components of biomass,” said Prof Ron Milo, at the Weizmann Institute of Science in Israel, who led the work, published in the Proceedings of the National Academy of Sciences.
“I would hope this gives people a perspective on the very dominant role that humanity now plays on Earth,” he said, adding that he now chooses to eat less meat due to the huge environmental impact of livestock. [Continue reading…]
More than 95% of world’s population breathe dangerous air, major study finds
More than 95% of the world’s population breathe unsafe air and the burden is falling hardest on the poorest communities, with the gap between the most polluted and least polluted countries rising rapidly, a comprehensive study of global air pollution has found.
Cities are home to an increasing majority of the world’s people, exposing billions to unsafe air, particularly in developing countries, but in rural areas the risk of indoor air pollution is often caused by burning solid fuels. One in three people worldwide faces the double whammy of unsafe air both indoors and out.
The report by the Health Effects Institute used new findings such as satellite data and better monitoring to estimate the numbers of people exposed to air polluted above the levels deemed safe by the World Health Organisation. This exposure has made air pollution the fourth highest cause of death globally, after high blood pressure, diet and smoking, and the greatest environmental health risk. [Continue reading…]

There’s no scientific basis for race — it’s a made-up label
In the first half of the 19th century, one of America’s most prominent scientists was a doctor named Samuel Morton. Morton lived in Philadelphia, and he collected skulls.
He wasn’t choosy about his suppliers. He accepted skulls scavenged from battlefields and snatched from catacombs. One of his most famous craniums belonged to an Irishman who’d been sent as a convict to Tasmania (and ultimately hanged for killing and eating other convicts). With each skull Morton performed the same procedure: He stuffed it with pepper seeds—later he switched to lead shot—which he then decanted to ascertain the volume of the braincase.
Morton believed that people could be divided into five races and that these represented separate acts of creation. The races had distinct characters, which corresponded to their place in a divinely determined hierarchy. Morton’s “craniometry” showed, he claimed, that whites, or “Caucasians,” were the most intelligent of the races. East Asians—Morton used the term “Mongolian”—though “ingenious” and “susceptible of cultivation,” were one step down. Next came Southeast Asians, followed by Native Americans. Blacks, or “Ethiopians,” were at the bottom. In the decades before the Civil War, Morton’s ideas were quickly taken up by the defenders of slavery.
“He had a lot of influence, particularly in the South,” says Paul Wolff Mitchell, an anthropologist at the University of Pennsylvania who is showing me the skull collection, now housed at the Penn Museum. We’re standing over the braincase of a particularly large-headed Dutchman who helped inflate Morton’s estimate of Caucasian capacities. When Morton died, in 1851, the Charleston Medical Journal in South Carolina praised him for “giving to the negro his true position as an inferior race.”
Today Morton is known as the father of scientific racism. So many of the horrors of the past few centuries can be traced to the idea that one race is inferior to another that a tour of his collection is a haunting experience. To an uncomfortable degree we still live with Morton’s legacy: Racial distinctions continue to shape our politics, our neighborhoods, and our sense of self.
This is the case even though what science actually has to tell us about race is just the opposite of what Morton contended. [Continue reading…]

Land degradation by human activities pushing Earth into sixth mass extinction and undermining well-being of 3.2 billion people
Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES): Worsening land degradation caused by human activities is undermining the well-being of two fifths of humanity, driving species extinctions and intensifying climate change. It is also a major contributor to mass human migration and increased conflict, according to the world’s first comprehensive evidence-based assessment of land degradation and restoration.
The dangers of land degradation, which cost the equivalent of about 10% of the world’s annual gross product in 2010 through the loss of biodiversity and ecosystem services, are detailed for policymakers, together with a catalogue of corrective options, in the three-year assessment report by more than 100 leading experts from 45 countries, launched today.
Produced by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the report was approved at the 6th session of the IPBES Plenary in Medellín, Colombia. IPBES has 129 State Members.
Providing the best-available evidence for policymakers to make better-informed decisions, the report draws on more than 3,000 scientific, Government, indigenous and local knowledge sources. Extensively peer-reviewed, it was improved by more than 7,300 comments, received from over 200 external reviewers.
Serious Danger to Human Well-being
Rapid expansion and unsustainable management of croplands and grazing lands is the most extensive global direct driver of land degradation, causing significant loss of biodiversity and ecosystem services – food security, water purification, the provision of energy and other contributions of nature essential to people. This has reached ‘critical’ levels in many parts of the world, the report says.
“With negative impacts on the well-being of at least 3.2 billion people, the degradation of the Earth’s land surface through human activities is pushing the planet towards a sixth mass species extinction,” said Prof. Robert Scholes (South Africa), co-chair of the assessment with Dr. Luca Montanarella (Italy). “Avoiding, reducing and reversing this problem, and restoring degraded land, is an urgent priority to protect the biodiversity and ecosystem services vital to all life on Earth and to ensure human well-being.”
“Wetlands have been particularly hard hit,” said Dr. Montanarella. “We have seen losses of 87% in wetland areas since the start of the modern era – with 54% lost since 1900.”
According to the authors, land degradation manifests in many ways: land abandonment, declining populations of wild species, loss of soil and soil health, rangelands and fresh water, as well as deforestation.
Underlying drivers of land degradation, says the report, are the high-consumption lifestyles in the most developed economies, combined with rising consumption in developing and emerging economies. High and rising per capita consumption, amplified by continued population growth in many parts of the world, can drive unsustainable levels of agricultural expansion, natural resource and mineral extraction, and urbanization – typically leading to greater levels of land degradation.
By 2014, more than 1.5 billion hectares of natural ecosystems had been converted to croplands. Less than 25% of the Earth’s land surface has escaped substantial impacts of human activity – and by 2050, the IPBES experts estimate this will have fallen to less than 10%.
Crop and grazing lands now cover more than one third of the Earth´s land surface, with recent clearance of native habitats, including forests, grasslands and wetlands, being concentrated in some of the most species-rich ecosystems on the planet.
The report says increasing demand for food and biofuels will likely lead to continued increase in nutrient and chemical inputs and a shift towards industrialized livestock production systems, with pesticide and fertilizer use expected to double by 2050.
Avoidance of further agricultural expansion into native habitats can be achieved through yield increases on the existing farmlands, shifts towards less land degrading diets, such as those with more plant-based foods and less animal protein from unsustainable sources, and reductions in food loss and waste.
Strong Links to Climate Change
“Through this report, the global community of experts has delivered a frank and urgent warning, with clear options to address dire environmental damage,” said Sir Robert Watson, Chair of IPBES.
“Land degradation, biodiversity loss and climate change are three different faces of the same central challenge: the increasingly dangerous impact of our choices on the health of our natural environment. We cannot afford to tackle any one of these three threats in isolation – they each deserve the highest policy priority and must be addressed together.”
The IPBES report finds that land degradation is a major contributor to climate change, with deforestation alone contributing about 10% of all human-induced greenhouse gas emissions. Another major driver of the changing climate has been the release of carbon previously stored in the soil, with land degradation between 2000 and 2009 responsible for annual global emissions of up to 4.4 billion tonnes of CO2.
Given the importance of soil’s carbon absorption and storage functions, the avoidance, reduction and reversal of land degradation could provide more than a third of the most cost-effective greenhouse gas mitigation activities needed by 2030 to keep global warming under the 2°C threshold targeted in the Paris Agreement on climate change, increase food and water security, and contribute to the avoidance of conflict and migration.
Projections to 2050
“In just over three decades from now, an estimated 4 billion people will live in drylands,” said Prof. Scholes. “By then it is likely that land degradation, together with the closely related problems of climate change, will have forced 50-700 million people to migrate. Decreasing land productivity also makes societies more vulnerable to social instability – particularly in dryland areas, where years with extremely low rainfall have been associated with an increase of up to 45% in violent conflict.”
Dr. Montanarella added: “By 2050, the combination of land degradation and climate change is predicted to reduce global crop yields by an average of 10%, and by up to 50% in some regions. In the future, most degradation will occur in Central and South America, sub-Saharan Africa and Asia – the areas with the most land still remaining that is suitable for agriculture.”
The report also underlines the challenges that land degradation poses, and the importance of restoration, for key international development objectives, including the United Nations Sustainable Development Goals and the Aichi Biodiversity Targets. “The greatest value of the assessment is the evidence that it provides to decision makers in Government, business, academia and even at the level of local communities,” said Dr. Anne Larigauderie, Executive Secretary of IPBES. “With better information, backed by the consensus of the world’s leading experts, we can all make better choices for more effective action.”
Options for Land Restoration
The report notes that successful examples of land restoration are found in every ecosystem, and that many well-tested practices and techniques, both traditional and modern, can avoid or reverse degradation.
In croplands, for instance, some of these include reducing soil loss and improving soil health, the use of salt tolerant crops, conservation agriculture and integrated crop, livestock and forestry systems.
In rangelands with traditional grazing, maintenance of appropriate fire regimes, and the reinstatement or development of local livestock management practices and institutions have proven effective.
Successful responses in wetlands have included control over pollution sources, managing the wetlands as part of the landscape, and reflooding wetlands damaged by draining.
In urban areas, urban spatial planning, replanting with native species, the development of ‘green infrastructure’ such as parks and riverways, remediation of contaminated and sealed soils (e.g. under asphalt), wastewater treatment and river channel restoration are identified as key options for action.
Opportunities to accelerate action identified in the report include:
- Improving monitoring, verification systems and baseline data;
- Coordinating policy between different ministries to simultaneously encourage more sustainable production and consumption practices of land-based commodities;
- Eliminating ‘perverse incentives’ that promote land degradation and promoting positive incentives that reward sustainable land management; and
- Integrating the agricultural, forestry, energy, water, infrastructure and service agendas.
Making the point that existing multilateral environmental agreements provide a good platform for action to avoid, reduce and reverse land degradation and promote restoration, the authors observe, however, that greater commitment and more effective cooperation is needed at the national and local levels to achieve the goals of zero net land degradation, no loss of biodiversity and improved human well-being.
Knowledge Gaps
Among the areas identified by the report as opportunities for further research are:
- The consequences of land degradation on freshwater and coastal ecosystems, physical and mental health and spiritual well-being, and infectious disease prevalence and transmission;
- The potential for land degradation to exacerbate climate change, and land restoration to help both mitigation and adaptation;
- The linkages between land degradation and restoration and social, economic and political processes in far-off places; and
- Interactions among land degradation, poverty, climate change, and the risk of conflict and of involuntary migration.
Environmental and Economic Sense
The report found that higher employment and other benefits of land restoration often exceed by far the costs involved. On average, the benefits of restoration are 10 times higher than the costs (estimated across nine different biomes), and, for regions like Asia and Africa, the cost of inaction in the face of land degradation is at least three times higher than the cost of action.
“Fully deploying the toolbox of proven ways to stop and reverse land degradation is not only vital to ensure food security, reduce climate change and protect biodiversity,” said Dr. Montanarella, “It’s also economically prudent and increasingly urgent.”
Echoing this message, Sir Robert Watson, said: “Of the many valuable messages in the report, this ranks among the most important: implementing the right actions to combat land degradation can transform the lives of millions of people across the planet, but this will become more difficult and more costly the longer we take to act.”
Great Pacific Garbage Patch now covers area three times the size of France
Seventy-nine thousand tons of plastic debris, in the form of 1.8 trillion pieces, now occupy an area three times the size of France in the Pacific Ocean between California and Hawaii, a scientific team reported on Thursday.
The amount of plastic found in this area, known as the Great Pacific Garbage Patch, is “increasing exponentially,” according to the surveyors, who used two planes and 18 boats to assess the ocean pollution.
“We wanted to have a clear, precise picture of what the patch looked like,” said Laurent Lebreton, the lead oceanographer for the Ocean Cleanup Foundation and the lead author of the study.
The Garbage Patch has been described before. But this new survey estimates that the mass of plastic contained there is four to 16 times larger than previously supposed, and it is continuing to accumulate because of ocean currents and careless humans both onshore and offshore. [Continue reading…]

Sudan, the last male northern white rhinoceros, dies in Kenya
The last male northern white rhinoceros died on Monday at the Ol Pejeta Conservancy in Kenya following a series of infections and other health problems.
At 45, Sudan was an elderly rhino, and his death was not unexpected. Hunted to near-extinction, just two northern white rhinos now remain: Najin, Sudan’s daughter, and Fatu, his granddaughter, both at the conservancy.
The prospect of losing the charismatic animals has prompted an unusual scientific effort to develop new reproductive technology in hopes of saving them.
“This is a creature that didn’t fail in evolution,” said Thomas Hildebrandt, head of reproduction management at the Leibniz Institute for Zoo and Wildlife Research in Berlin and one of the project’s leaders. “It’s in this situation because of us.” [Continue reading…]
After a volcano’s ancient supereruption, humanity may have thrived
The Toba supereruption [about 74,000 years ago] expelled roughly 10,000 times more rock and ash than the 1980 Mount St. Helens eruption. So much ejecta would have darkened skies worldwide, causing scientists to speculate that it might have plunged the Earth into a volcanic winter whose chill could be felt far from Indonesia. Climate models suggest that temperatures may have plummeted by as much as 30 degrees Fahrenheit. And in such a cold world, plants may have ceased growing, glaciers may have advanced, sea-levels may have dropped and rainfall may have slowed.
Then in 1998, Stanley Ambrose, an anthropologist, linked the proposed disaster to genetic evidence that suggested a population bottleneck had occurred around the same time. He was certain that the Toba supereruption had caused the human population to decline to some 10,000 people — a close call for our ancestors.
“These were dramatic theories,” said Michael Petraglia, an archaeologist at the Max Planck Institute for the Science of Human History who was not involved in the study. “They were very popular — both in the scientific world, but also in the public imagination.”
The latest study, however, suggests that those theories are incorrect, Dr. Petraglia said. “We’re not seeing all the drama.” [Continue reading…]

Women in Iran are pulling off their headscarves — and hoping for a ‘turning point’
Iranian women have been raising a new challenge to their Islamic government, breaking one of its most fundamental rules by pulling off their headscarves in some of the busiest public squares and brandishing them in protest.
While these guerrilla protesters number only in the dozens, Iran’s government has taken notice of their audacity. On Thursday, planned demonstrations to coincide with International Women’s Day were preempted by a heavy police presence on the streets of the capital, Tehran.
Iran’s Supreme Leader Ayatollah Ali Khamenei marked the day with sharply worded tweets skewering Western countries for the immodesty of their women and trumpeting the virtues of the headscarf, or hijab.
“By promoting modest dress (#hijab), #Islam has blocked the path which would lead women to such a deviant lifestyle,” Khamenei tweeted in English. “Iranian women today, declare their . . . independence and export it to the world while preserving their #hijab.”
It was precisely the opposite message that one young woman hoped to send when she climbed atop a tall, metal utility box on a Tehran sidewalk in January and took off her headscarf, hoisting it overhead on a stick for all to see. [Continue reading…]
