For decades, intensive groundwater pumping has caused ground beneath California’s San Joaquin Valley to sink, damaging infrastructure. Now research published in the journal Nature Communications suggests that as pumping makes the ground sink, it also unleashes an invisible threat to human health and food production: It allows arsenic to move into groundwater aquifers that supply drinking water for 1 million people and irrigation for crops in some of the nation’s richest farmland.

In a remote region of the Indian Ocean lies the source of a mysterious weather pattern with tentacles that stretch across the tropics, influencing everything from monsoons in India to heat waves and flooding in the United States.

British Columbia’s premier shellfish farming region is heavily contaminated with microplastics, according to a new Simon Fraser University study.

Since the 1960s, scientists at the University of Vermont have been documenting the decline of red spruce trees, casualties of the damage caused by acid rain on northeastern forests.

But now, surprising new research shows that red spruce are making a comeback—and that a combination of reduced pollution mandated by the 1990 Amendments to the Clean Air Act and changing climate are behind the resurgence.

Newly published results from a study on nutrition, food security and the environment in Saskatchewan First Nations show that food insecurity is a major concern and that many households would like more access to traditional foods.
