Reinforcing the Diverse Ways People Access Seafood Can Ensure Healthy Communities in the Face of Change

As climate change affects the oceans, coastal communities, particularly those at the front lines of ocean warming and sea level rise, are facing pressures that could threaten their access to aquatic foods. “Climate change and other economic shocks are impacting how people access seafood, and typically households that are most reliant on seafood, such as...

Sustainable Practices Can Save Mexico’s Blue Agave, Tequila and Bats

Many associate tequila with lime wedges, salt, and parties. But the popular drink also has a negative impact on biodiversity, both on the blue agave from which it is made and, perhaps more unexpectedly, on bats. Both are threatened by one-sided cultivation. Researchers at the University of Gothenburg, together with colleagues in Mexico and the...

Brazil Can Lead the World in the Production of Green Hydrogen from the Sun and Wind

In the context of the international search for energy transition alternatives, one of the most promising topics today is green hydrogen. And Brazil is one of the countries best placed to lead the production of this abundant, cheap and potentially efficient energy alternative. But after all, what is green hydrogen, and why does Brazil have...

As Cities Grow, How Will City Trash, Wastewater, and Emissions Rise?

More than half of the world’s population—4.4 billion people—lives in cities, and that proportion will grow to two-thirds by the year 2050, according to the United Nations. As the world’s population expands, and becomes increasingly urbanized, many have raised concerns about the impact of waste—from house trash to wastewater to greenhouse gas emissions—on the planet....

What If Cows Could Talk?

By using acoustic data and machine learning to decipher cows’ vocalizations, Virginia Tech researchers hope to shed new light on the animals’ health, welfare, and environmental impact. You may not know it, but cows share information every time they burp, moo, and chew that speaks volumes about their health and welfare. Through the work of...

The Uncomfortable Geopolitics of the Clean Energy Transition

Every time UN Secretary General Antonio Guterres speaks about the climate crisis, he ups the ante with his admonishments—and rightly so. In September, when he said “humanity had opened the gates of hell,” it was at the end of a summer of unprecedented flooding, including in Libya, China, and the United States, and record-breaking fires in Canada and...

Electrifying Vehicles in Chicago Would Save Lives, Reduce Pollution Inequities

If the Chicago region replaced 30% of all on-road combustion-engine vehicles — including motorcycles, passenger cars and trucks, buses, refuse trucks and short- and long-haul trucks — with electric versions, it would annually save more than 1,000 lives and over $10 billion, according to a new Northwestern University study. The new study, which simulates air...

Closure of Pittsburgh Coal-Processing Plant Tied to Local Health Gains

The closure in January 2016 of one of Pittsburgh’s biggest coal-processing plants led to immediate and lasting declines in emissions of fossil fuel-related air pollutants. These in turn were linked to near-instant decreases in local heart-related emergency department visits and hospitalizations for cardiovascular diseases, a new study shows. The impact of the closure persisted through...

What Does Narcissism Have to Do with Ecology?

A group of researchers from the Nicolaus Copernicus University, the SWPS University in Warsaw, and the University of Waikato in New Zealand have for some time been scientifically looking at the relationship between different types of identifications with a group and attitudes towards, for example, science, vaccines and workplace behaviour. This time they were interested...
