For a lot of farmers in Colorado, and across the country, insecticides known as neonicotinoids, or neonics, have been a game changer. But what’s been a breakthrough for some has been a nightmare for others. Neonics are being blamed for die-offs in domestic bees and native pollinators, and there’s growing concern over their potential impacts on human health as well.
