More than 40 percent of insects could go extinct globally in the next few decades. So why did the U.S. Environmental Protection Agency (EPA) last week OK the 'emergency' use of the bee-killing pesticide sulfoxaflor on 13.9 million acres?
EcoWatch teamed up with Center for Biological Diversity via EcoWatch Live on Facebook to find out why. Environmental Health Director and Senior Attorney Lori Ann Burd explained how there is a loophole in the The Federal Insecticide, Fungicide, and Rodenticide Act under section 18, "that allows for entities and states to request emergency exemptions to spraying pesticides where they otherwise wouldn't be allowed to spray."

Most people know that monarch butterflies can't exist without milkweed. As caterpillars, the monarchs feed on milkweed plants exclusively, absorbing the milkweed's poisons in order to ward off birds and other predators. On their epic migration across the North American continent, the butterflies also lay their eggs on these plants, relying on the noxious taste of the leaves to keep their brood safe from grazers while simultaneously providing a buffet for the next generation when it hatches.
The Migration and Importance of Monarchs
Monarch butterflies, which pollinate many different kinds of wildflowers, are among nature's great wonders. Their annual migration is one of the most awe-inspiring on Earth: Each fall, millions of these striking black-and-orange butterflies take flight on a 3,000-mile journey across the U.S. and Canada to wintering grounds in Mexico's Sierra Madre mountains.

Dicamba—a drift-prone herbicide linked to millions of acres of off-target crop damage across in 17 states—destroys mostly everything in its path except the crops that are genetically engineered to resist it. It's so damaging that several states, including Arkansas, Tennessee and Missouri have introduced temporary bans on the weedkiller.
There's now another reason to worry about the controversial chemical. It's particularly harmful to milkweed, the only host plant for the iconic and already at-risk monarch buttery.
