Seed banks: the last line of defense against a threatening global food crisis

By -

By Salomé Gómez-Upegui and Rita Liu. The Guardian. 

Excerpt: As the risks from the climate crisis and global conflict increase, seed banks are increasingly considered a priceless resource that could one day prevent a worldwide food crisis. Two in five of the world’s plant species are at risk of extinction, and though researchers estimate there are at least 200,000 edible plant species on our planet, we depend on just three – maize, rice and wheat– for more than half of humanity’s caloric intake. There are roughly 1,700 seed banks, or gene banks, around the world housing collections of plant species that are invaluable for scientific research, education, species preservation and safeguarding Indigenous cultures. “At a first glance, seeds may not look like much, but within them lies the foundation of our future food and nutrition security, and the possibility for a world without hunger,” said Stefan Schmitz, executive director of the Global Crop Diversity Trust, an organization dedicated to preserving crop diversity for food security. “Well-funded, well-maintained seed banks are critical to reducing the negative impact of the climate crisis on our agriculture globally.”…

Lost history of Antarctica revealed in octopus DNA

https://www.science.org/content/article/lost-history-antarctica-revealed-octopus-dna By ERIK STOKSTAD .  Excerpt: Some 100,000 years ago, scientists believe Antarctica’s massive western ice sheet collapsed, temporarily opening waterways between a trio of seas surrounding the continent. New evidence for that scenario comes from a surprising source: octopus DNA. ...About 129,000 to 116,000 years ago, a warm spell called the last interglacial gave our planet a brief break in between several million years of ice ages. The average temperature of the planet was about 0.5°C warmer than it is today—and climate projections predict it will be again within decades. The global sea level was also 5 meters to 10 meters higher than current levels. Many scientists believe  the collapse of the West Antarctic Ice Sheet and consequent melting could have been a primary reason . ...The findings are consistent with growing geological evidence supporting the ice sheet collapse....

Where Glaciers Melt, the Rivers Run Red

By -
By Mitra Taj , The New York Times.  Excerpt: As the glaciers of South America retreat, the supply of freshwater is dwindling and its quality is getting worse. Dionisia Moreno, a 70-year-old Indigenous farmer, still remembers when Shallap River, nearly 13,000 feet up in the Cordillera Blanca, brought crystal clear water brimming with trout to her village, Jancu. “People and animals alike could drink the water without suffering,” she said. “Now the water is red. No one can drink it.”....  Full article at https://www.nytimes.com/2024/11/19/science/peru-glaciers-water-pollution.html .

The first people on Tasmania brought fire and forever changed the land

By -
By Warren Cornwall , Science.  Excerpt: More than 41,000 years ago, humans traversed a strip of land that once joined the mainland of Australia to what is today the island of Tasmania, called Lutruwita by its Indigenous inhabitants today. The first humans to reach this land brought a tool they used to transform the landscape and that left the first lasting marks of their presence: fire. Thanks to layers of sediment that formed year by year along the bottom of a lake on a small island off the northeastern tip of Lutruwita, scientists have for the first time chronicled the region’s history of vegetation spanning more than 50,000 years. They found  a surge in fires starting about 41,600 years ago , the researchers report today in Science Advances, the same time as falling sea levels opened a dry corridor allowing humans to migrate to the island. ...The findings come at a time of growing interest in reviving a traditional burning culture on Lutruwita. Aboriginal communities a...
