Sprawling mining operations in Brazil have caused roughly 10 percent of all Amazon rainforest deforestation between 2005 and 2015 — much higher than previous estimates — says the first comprehensive study of mining deforestation in the iconic tropical rainforest. Surprisingly, the majority of mining deforestation (a full 90%) occurred outside the mining leases granted by Brazil’s government, the new study finds… Continue reading
Oregon shore crabs exhibit risky behavior when they’re exposed to the antidepressant Prozac, making it easier for predators to catch them, according to a new study… Continue reading
A study conducted at the Max Planck Institute for Human Development has investigated the relationship between the availability of nature near city dwellers’ homes and their brain health. Its findings are relevant for urban planners among others… Continue reading
Massive amounts of plastic bits that are dangerous to aquatic life are washing into the oceans and into even the most pristine waters. But how it all gets there from inland cities has not been fully understood. Now scientists have found that 10 rivers around the world where plastic waste is mismanaged contribute to most of the oceans’ total loads that come from rivers… Continue reading
Look at a hundred lakes in the United States’ agricultural heartland and you’ll likely see green lakes surrounded by green fields. Agricultural fertilizers that help crops grow also fuel growth of algae and cyanobacteria that in excess can turn lakes the color of pea soup. Yet when scientists looked at 13 years of data from 139 lakes in intensively agricultural areas of Iowa they saw lakes that were surprisingly clear despite extremely high nutrient concentrations… Continue reading
Concentration of carbon dioxide during an intense period of global warmth may have been as low as half the level previously suggested by scientists, according to a new Dartmouth College study… Continue reading
Soils keep plants healthy by providing plants with water, helpful minerals, and microbes, among other benefits. But what if the soil also contains toxic elements?
In areas like Salinas Valley, California, the soils are naturally rich in the element cadmium. Leafy vegetables grown in these soils can take up the cadmium and become harmful to humans. What to do? The solution goes back to the soil. Adrian Paul, a former researcher now working in the Sustainable Mineral Institute in Brisbane, Australia, is working to find which soil additives work best.

A new IUPUI study funded by the U.S. Department of Agriculture answers a long-debated agricultural question: whether no-tillage alone is sufficient to prevent water pollution from nitrate. The answer is no… Continue reading
Climate policies that target agriculture and forests could lead to increased food prices, but reducing deforestation and increasing soil carbon sequestration in agriculture could significantly reduce greenhouse gas emissions while avoiding risk to food security, according to new research published in the journal Environmental Research Letters… Continue reading
