EATING CRICKETS: As part of a project about food sustainability and water resource usage, learn about protein bars made out of crickets.

GMOs: Many farmers have substituted pesticides with genetically modified organisms. GMOs protect crops from harmful insects and pests, without having much harmful baggage toward humans. However, depending on the crop, insects' continuous exposure to GMOs can evolve into resistance.

SKY ISLAND ORGANISMS: Southeastern Arizona is also known as the Sky Island region. It is one of the most biologically diverse areas in North America, and a hot bed for arthropods, organisms that have skeletons outside of their body. Local examples include beetles, scorpions and tarantulas.

During his career, Schmidt has studied mostly bees, wasps and ants, causing him to feel the pain of almost every biting and stinging species he has encountered. Watch what he had to say about his occupation in a story published by Arizona Public Media's UA+ from July 2012.
