From Cyprus to New Zealand, Lebanon and beyond, environmentalists worry about the proliferation of quarries in a world ever greedier for concrete. Concrete consumption has tripled over the past 20 year.

Over 40 billion tons a year of sand and gravel are extracted around the world from mountains, rivers, coastlines and marine environments, the majority for construction. With the global population expected to grow by two billion by 2050, demand can only go up, according to the UN environment agency. The extraction process often comes with deforestation, air pollution and disruption of traditional human activities.

This is the case in Cyprus, near the hut where Jamal makes traditional "hellim" cheese, trucks come to collect rock, kicking up clouds of dust and frightening the animals.

On the quarried area of the mountain slope, vegetation has disappeared. A policeman asks the goat herder to stay back as an explosion triggers a huge cloud of smoke and part of the rock face collapses. On another mountain, Jamal was injured and lost animals to quarrying work.

Rocks "rained down on us," he recalled.

While he understands the "need for rock to build", he hopes the company running the site will help him find quieter pastures in the Turkish Republic of Northern Cyprus established in 1974, and on which live 355,000 people. This region walks the line between development and conservation.

Cenk Sarper, head of the Stone Quarries Union, said: "Today, the island is fed by tourism so we need hotels, guest houses, roads and airports. We don't have any other choice than to exploit the quarries."

He said the quarries operate in areas far from residential zones and respect all the adopted environmental standards. More than 12,000 tons of rock is extracted every day, or around 33 kilograms per capita. The world average is 18 kilograms, according to the UN.

Asking to remain anonymous, a contractor said that key actors "did not do everything possible to limit visual pollution." Some accuse companies from Turkey of being less vigilant than Turkish Cypriot ones.

The secretary general of the biologists' association in northern Cyprus, Hasan Sarpten, regrets that a large quarry was authorized far from a reserved area, in the west.

"They are not applying the best methods" environmentally, he said, criticizing the lack of regulation by Turkish Cypriot authorities.

These authorities declined to comment when contacted by AFP.

Environmentalists are equally worried in the internationally recognized Republic of Cyprus.

Environment expert Klitos Papastylianou said: "The growing extraction of raw materials for the construction industry is one of the main threats for protected areas."

Green Party MP Charalampos Theopemptou noted that "marinas and coast protection works require huge amounts of rocks."

An audit recommended increasing fines to discourage illegal quarrying. Calls for stricter controls resound around the world. In Lebanon, where illegal quarries have cleared entire mountains and hundreds of thousands of trees, activists are pushing back, despite death threats.

Hawaii's Kilauea was spraying a spectacular fountain of lava on Monday, keeping up its reputation as one of the world's most active volcanoes.

For over a year now, Kilauea has been regularly throwing out thousands of tons of molten rock and gases since it burst to life in December 2024, reported AFP.

Volcanologists with the US Geological Survey said the incandescent lava was being hurled more than 1,500 feet (460 meters) into the air, with plumes of smoke and gases rising as high as 20,000 feet (six kilometers).

Eruptions such as this one tend to last around one day, the USGS said, but can still vent up to 100,000 tons of sulfur dioxide.

This gas reacts in the atmosphere to create a visible haze known as vog -- volcanic smog -- which can cause respiratory and other problems.

Tiny slivers of volcanic glass, known as "Pele's hair," are also being thrown into the air.

Named after Pele, the Hawaiian goddess of volcanoes, the strands can be very sharp and can cause irritation to the skin and eyes.

The eruption poses no immediate danger to any human settlement, with the caldera having been closed to the public for almost two decades.

Kilauea has been very active since 1983 and erupts relatively regularly.

It is one of six active volcanoes located in the Hawaiian Islands, which also include Mauna Loa, the largest volcano in the world.

Kilauea is much smaller than neighboring Mauna Loa, but it is far more active and regularly wows helicopter-riding tourists who come to see its red-hot shows.


Astronaut's Serious Medical Condition Forces NASA to End Space Station Mission Early

NASA announced that four astronauts will return from the International Space Station more than a month ahead of schedule after an unnamed crew member experienced a medical issue.

The incident marks the first time in history NASA has brought astronauts home from the space station early because of a medical issue, according to CNN.

NASA has not provided details about the nature of the problem, citing privacy concerns. The agency typically does not discuss the specifics of health matters related to astronauts.

A SpaceX Crew Dragon capsule will bring the four-person crew home, disembarking from the ISS as soon as Wednesday at 5 pm ET. The spacecraft is then expected to splash down off the coast of California early the following morning, NASA said in a statement last week.

The affected astronaut is in stable condition, NASA previously confirmed, and is not expected to receive special treatment during the return trip, said Dr James Polk, NASA’s chief health and medical officer at the agency’s headquarters.

The astronaut would also be best served by being evaluated on the ground, Polk added.

“We have a very robust suite of medical hardware on board the International Space Station,” Polk noted during a news conference. “But we don’t have the complete amount of hardware that I would have in the emergency department, for example, to complete a workup of a patient.”

He added, “And in this particular incident, we would like to complete that work up, and the best way to complete that workup is on the ground.”

Astronomers have observed a white dwarf - a highly compact Earth-sized stellar ember - that is creating a colorful shockwave as it moves through space, leaving them searching for an explanation.

The highly magnetized white dwarf is gravitationally bound to another star in what is called a binary system. The white dwarf is siphoning gas from its companion as the two orbit close to each other. The system is located in the Milky Way about 730 light-years from Earth - relatively nearby in cosmic terms - in the constellation Auriga.

A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

The shockwave - more specifically a bow shock - caused by the white dwarf was observed using the European Southern Observatory's Chile-based Very Large Telescope. The shockwave was seen in an image released by the scientists glowing in various colors produced when material flowing outward from the white dwarf collided with interstellar gas.

"A shockwave ‌is created when ‌fast-moving material plows into surrounding gas, suddenly compressing and heating it. A ‌bow shock ⁠is the curved ‌shock front that forms when an object moves rapidly through space, similar to the wave in front of a boat moving through water," said astrophysicist Simone Scaringi of Durham University in England, co-lead author of the study published on Monday in the journal Nature Astronomy.

"The colors come from interstellar gas that is being heated and excited by the shock. Different chemical elements glow at specific colors when this happens," Scaringi added.

In this shockwave, a red hue represented hydrogen, green represented nitrogen and blue represented oxygen residing in interstellar space.

A handful of other white dwarfs have been observed creating shockwaves. But all of those were ⁠surrounded by disks of gas siphoned from a binary partner. Although this white dwarf is siphoning gas from its companion, it lacks any such disk and ‌is releasing gas into space for unknown reasons.

White dwarfs are among the ‍universe's most compact objects, though not as dense as ‍black holes.

Stars with up to eight times the mass of the sun appear destined to end up as ‍a white dwarf. They eventually burn up all the hydrogen they use as fuel. Gravity then causes them to collapse and blow off their outer layers in a "red giant" stage, eventually leaving behind a compact core - the white dwarf.

"There are plenty of white dwarfs out there, as these are the most common endpoints of stellar evolution," Scaringi said.

The sun appears fated to end its existence as a white dwarf, billions of years from now.

This white dwarf has a mass comparable to the sun contained in a body slightly larger than Earth. Its binary companion is ⁠a type of low-mass star called a red dwarf that is about a tenth the mass of the sun and thousands of times less luminous. It orbits the white dwarf every 80 minutes, with the two extremely close to each other - approximately the distance between the moon and Earth.

The gravitational strength of the white dwarf is pulling gas off the red dwarf. This siphoned material is being pulled into the white dwarf along its strong magnetic field, eventually landing at its magnetic poles. While this process releases energy and radiation, it cannot account for the outflow of material needed to produce the observed shockwave, Scaringi said.

"Every mechanism with outflowing gas we have considered does not explain our observation, and we still remain puzzled by this system, which is why this result is so interesting and exciting," Scaringi said.

"The shape and length of the (shockwave) structure show that this process has been ongoing for at least about 1,000 years, making it long-lived rather than a one-off event," Scaringi added.

The ‌researchers took note of the aesthetics of the colorful shockwave.

"Beyond the science, it's a striking reminder that space is not empty or static as we may naively imagine it: it's dynamic and sculpted by motion and energy," Scaringi said.
