Colorado is known as the "Headwaters State” because eight major rivers originate there, including the Colorado, Arkansas, Rio Grande, and Platte. Unlike many other states in the U.S., all of the water in Colorado comes from snow and rain, which is a source of water for many other states.
The Southwest and Northeast saw the greatest loss in spring snowpack between 1981 and 2020, raising concerns about water scarcity and economies reliant on winter recreation. The numbers at bottom correspond to the percentage of spring snowpack lost (red) or gained (blue) per decade, with losses concentrated in populated regions. | Image Credit: Justin Mankin and Alexander Gottlieb
The Red Sea that lies between the east coast of Africa and the west coast of the Arabian peninsula is crucial to maintaining the political and economic stability of many countries, according to the Kiel Institute for the World Economy. It’s one of the busiest shipping lanes with more than 30,000 vessels passing every year and comprising 12 percent of global trade, including about 30 percent of all container ships. It’s the shortest route by sea between Europe and Asia via the Suez Canal.
Microplastics have been found everywhere on Earth from the deep ocean to the tallest mountains—and they’re also in us from what we eat and drink. Plastic leaches from food packaging, is in fruits and vegetables we eat that are irrigated with contaminated water, and is in fish we consume that might have ingested the particles floating in the ocean. A new study by researchers with the nonprofit Ocean Conservancy and the University of Toronto found microplastics in nearly 90 percent of protein food samples tested.
Using newly refined technology called stimulated Raman scattering microscopy, researchers are able to see nanoplastics. | Image credit: Naixin Qian/Columbia University
If you’re a wine drinker, would you consider buying a Cabernet or Rosé if it came in an aluminum can or box rather than a bottle? Would you if you learned that bottles have higher carbon footprints? Research led by the University of South Australia wanted to find out if alternatives like bag-in-box or cask wine would appeal to consumers if they knew that the environmentally friendly options were up to 51 percent more carbon efficient than glass.
