Editor's note

A new front has opened in the Trump administration’s trade war with the world. When the White House announced tariffs on foreign steel and aluminum back in March, it granted the European Union, Canada and Mexico temporary exemptions. The administration recently chose to end the reprieve, angering the three biggest buyers of American goods and drawing retaliation. William Hauk, an economist at the University of South Carolina, uses four charts to show why imposing tariffs on your closest friends is a bad idea.

On World Environment Day yesterday, the United Nations published a report encouraging governments and businesses to replace single-use plastic with new materials to reduce the quantity of plastic trash in the oceans and on the shoreline. New research shows that microplastic littering beaches may alter the nesting sites of sea turtles and threaten these species.

And while most people may have witnessed separation anxiety in a child, the separation anxiety migrant children experience is different and often more serious, writes Wayne State University psychiatrist David Rosenberg. Such prolonged separation “is never easy and the hidden scars remain.”
