Insect farming is also one of the easiest ways- particularly for urbanites and/or those worried about food safety- to actively get in touch with your protein. Bugs require very little space to live and not a lot of care. Martinez, who is also an artist dedicated to micro architectural structures (i.e. small farms), created a home mealworm farm called Wurmhaus.
Mealworms are very low-maintenance livestock: they eat simply oats (or other grains) and for water, they need just pieces of vegetable or fruit (Martinez uses carrots). Though it does take a year to complete their lifecycle stages between egg, larva, pupa and adult beetle and since only the larvae are eaten, this involves some moving of eggs/beetles between homes.
