Professor Eshel writes that if Americans choose to reduce meat consumption, it would improve water quality, biodiversity, soil health, and food security, as well as slowing climate change.

Who you are can affect the quality of care you get as a woman in the U.S. health-care system, writes Bard alum Amanda King CEP ’18. Each year, more than 700 women die in the United States due to pregnancy or causes related to childbirth. Yet nearly 60 percent of all maternal deaths are preventable. One of the factors behind the numbers is the uneven quality of prenatal and postpartum care—a reflection of racial and ethnic disparities within the U.S. medical system.

The use of prescription stimulants by those without medically diagnosed conditions marks a growing trend among young adults—particularly college students seeking a brain boost. A new study coauthored by cognitive scientist Sara Mednick ’95 finds that nonprescribed psychostimulants may slightly improve a person’s short-term focus but impede sleep and mental functions that rely on it—such as working memory.

By replacing meat with protein-conserving plant alternatives Americans could satisfy key nutritional requirements, while eliminating pastureland use and reducing 35-50 percent of the cropland currently needed for food production in the United States, says a new study coauthored by Bard College Research Professor Gidon Eshel. The findings, part of modeling study published in Scientific Reports, suggest that use of nitrogen fertilizer and greenhouse gas emissions would also be reduced, while only food-related water use would rise.
“While widely replacing meat with plants is logistically and culturally challenging, few competing options offer comparable multidimensional resource use reduction,” write Eshel and coauthors Paul Stainier, Alon Shepon, Akshay Swaminathan, all of Harvard University.
In their study, “Environmentally Optimal, Nutritionally Sound, Protein and Energy Conserving Plant Based Alternatives to U.S. Meat,” Eshel and his coauthors used a computer model to devise hundreds of plant-based diets to replace either beef alone or all three dominant U.S. meat types: beef, poultry and pork. Plant-based diets consisted predominantly of soy, green pepper, squash, buckwheat and asparagus. The authors’ goal was to model a range of plant replacement diets that were at least as nutritious, if not more beneficial, than the meats they replaced, while also assessing their environmental impact. Diets were modeled to exactly match the protein content of the meat they replace—13 grams of protein per day from beef or 30 grams of protein per day from all three meat types—while also satisfying 43 other nutrient requirements, such as vitamins and fatty acids.
Buckwheat and tofu jointly delivered a full third of the total protein of diets that replaced all meats, yet accounted for only 12 percent of the nitrogen fertilizer and water and less than 22 percent of the cropland needed to produce the meats they replaced. Soy contributed the most protein to beef-replacing diets, but accounted for only six percent of the overall nitrogen fertilizer needed to produce beef. Replacing meat with plant alternatives was estimated to save approximately 29 million hectares of cropland, three billion kilograms of nitrogen fertilizer, and 280 billion kilograms of carbon dioxide per year. Food-related water use was projected to rise by 15 percent.

“What this new technology proposes is to watch everything at once,” says Michel. “Sometimes it’s referred to as ‘combat TiVo’ because when an event happens somewhere in the surveilled area, you can potentially rewind the tape to see exactly what occurred, and rewind even further to see who was involved and where they came from.” The experimental high-altitude balloons promise a cheap monitoring platform that could follow multiple vehicles for extended periods. They are also subject to fewer restrictions and regulations than drones, raising privacy concerns.
