This leaves us with a delicate balance to navigate. Insects are part of the animal kingdom, and you might be surprised by the other types of creatures that are also considered to be animals. The biggest threat of losing pollinators is that it reduces our production of diverse crop types that we dont typically rely on solely for calories: fruits, vegetables and other crops that provide us with important dietary diversity and micronutrients, even if we dont get a lot of energy from them. Scorpions eat insects, other arachnids, small reptiles . Most of our staple crops cereals such as maize, wheat and rice; roots and tubers such as cassava; and legumes such as peas and lentils do not rely on bees and butterflies at all.

Factors behind the decline include, perhaps foremost among them, habitat changes wrought by humans, such as deforestation, and conversion of natural habitats for agriculture. This needs a better understanding of what agricultural inputs affect pollinator populations, and whether there are particular management practices such as specific timings or application rates that can limit the damage to insect populations. Nationwide collaborative process working to maintain and improve the management, productivity, and health of privately owned grazing land. The plant-eating insects are not the only ones affected.
