Science News reports: In shallow coastal waters of the Indian and Pacific oceans, a seagrass-scrounging cousin of the manatee is in trouble. Environmental strains like pollution and habitat loss pose a major threat to dugong (Dugong dugon) survival, so much so that in December, the International Union for Conservation of Nature upgraded the species’ extinction… Read More »
NPR reports: In the wake of wildfires, floods and droughts, restoring damaged landscapes and habitats requires native seeds. The U.S. doesn’t have enough, according to a report released Thursday. “Time is of the essence to bank the seeds and the genetic diversity our lands hold,” the National Academies of Sciences, Engineering and Medicine (NASEM) report… Read More »
Anthropocene magazine reports: Elephants been called a lot of things: the world’s largest land creatures, imperiled, majestic, charismatic. Now scientists have a few more terms for describing them: foresters and climate champions. In the jungles of equatorial Africa, scientists report that forest elephants play an important role in shaping the forest around them as they… Read More »
Miriam Frankel and Matt Warren write: Your gut is a bustling and thriving alien colony. They number in their trillions and include thousands of different species. Many of these microorganisms, including bacteria, archaea and eukarya, were here long before humans, have evolved alongside us and now outnumber our own cells many times over. Indeed, as… Read More »
Arwen E Nicholson and Raphaëlle D Haywood write: For decades, children have grown up with the daring movie adventures of intergalactic explorers and the untold habitable worlds they find. Many of the highest-grossing films are set on fictional planets, with paid advisors keeping the science ‘realistic’. At the same time, narratives of humans trying to… Read More »
The New York Times reports: Mammals in the ocean swim through a world of sound. But in recent decades, humans have been cranking up the volume, blasting waters with noise from shipping, oil and gas exploration and military operations. New research suggests that such anthropogenic noise may make it harder for dolphins to communicate and… Read More »
60 Minutes reports: In what year will the human population grow too large for the Earth to sustain? The answer is about 1970, according to research by the World Wildlife Fund. In 1970, the planet’s 3 and a half billion people were sustainable. But on this New Year’s Day, the population is 8 billion.… Read More »
Inside Climate News reports: Nearly 200 countries have signed off on an agreement that embeds the promotion of human rights and the “rights of nature” into a plan to protect and restore biodiversity through 2030. The 14-page document, while nonbinding, was adopted on Dec. 19, 2022 at COP15, a 12-day conference convened in Montreal under… Read More »
Science reports: As a motley medley of mycologists climbed the basalt slopes of the Lanín volcano earlier this year, the green foliage at lower elevations gave way to autumnal golds and reds. Chile’s famed Araucaria—commonly called monkey puzzle trees—soon appeared, their spiny branches curving jauntily upward like so many cats’ tails. Beneath the majestic trees,… Read More »
Georgina Gustin writes: A wildebeest has toppled into a ditch at the edge of a dusty track, its shoe-box-shaped head twisted upward, a single gaping chomp out of its flank. Isack Marembe and Kisham Makui study the animal’s body and everything around it, doing a roadside postmortem. “A hyena,” Marembe says. But the culprit wasn’t… Read More »
Veronique Greenwood writes: Nature, red in tooth and claw, is rife with organisms that eat their neighbors to get ahead. But in the systems studied by the theoretical ecologist Holly Moeller, an assistant professor of ecology, evolution and marine biology at the University of California, Santa Barbara, the consumed become part of the consumer in… Read More »
Jason Hickel et al, write: The global economy is structured around growth — the idea that firms, industries and nations must increase production every year, regardless of whether it is needed. This dynamic is driving climate change and ecological breakdown. High-income economies, and the corporations and wealthy classes that dominate them, are mainly responsible for… Read More »
Michael J Warren writes: In one of the oldest poems in English literature, there is a beautiful moment when a lone sailor, battling against stormy winter seas and his troubled soul, describes how birds have replaced human company for him on the ‘ice-cold way’ – an admission that carries both comfort and sardonic misery. His… Read More »
Stewart Patrick writes: The planet is in the midst of an environmental emergency, and the world is only tinkering at the margins. Humanity’s addiction to fossil fuels and voracious appetite for natural resources are accelerating climate change and degrading ecosystems on land and sea, threatening the integrity of the biosphere and thus the survival of… Read More »
Patrick Hughes writes: Five times in our planet’s history, adverse conditions have extinguished most of life. Now, scientists say, life on Earth could be in trouble again, with some even saying we could be entering a sixth mass extinction. No credible scientist disputes that we are in a crisis regarding the speed at which nature… Read More »
Fred Pearce writes: In 2009, the U.S. government turned more than 190,000 square miles of pristine ocean centered on the Mariana Trench in the remote Pacific into one of the world’s largest protected areas. The same year, Mexico completed a management plan for the Cabo Pulmo coral reef in the Gulf of California, covering just… Read More »
