Humans routinely interact with these herbivores in a variety of formats. Domesticated species or individuals (horse, guinea pig, elephant) have long histories of providing labor, food, and entertainment for humans. Others have been hunted for their pelts, bones, or meat (beaver, hippopotumus, zebra, wild ass, manatee). Some are hunted and killed as pests (short-eared bushtail possum, common wombat, tammar wallaby, several rodent species). Many species are vectors or intermediates in parasitic or infectious diseases that affect humans (rats, mice, primates). In short, their dietary preferences place these herbivores in the middle links of food chains or ecosystems, animals designed to convert biomass from photosynthesis to biomass to be used by subsequent links in the biological systems of the earth.
