We all hate it when bugs crash a good picnic, but here's the thing: insects are vital to our survival, and studies show we are wiping them out.

A recent study out of Germany is showing that over the past three decades insects have been dying off in dramatic numbers, especially the ones that like to fly and pollinate the crops humans rely on to survive. Although the study’s numbers are specific to areas like protected grasslands and forests in Germany, scientists believe the general causes for the decrease-as much as 75% fewer flying insects-are evident worldwide. The Living Planet Index that tracks global biodiversity also shows wildlife numbers dropping by as much as 58% across the planet. While climate change is a natural suspect, some experts feel pesticide use and urbanization are also potential factors in the downward population trends.
