In the event massive body removal becomes necessary, that which the body removal services cannot do, the birds will be "the clean-up crew".
"Vultures are often underappreciated misunderstood birds. While there may be only 23 vulture species in the world, depending on how individual species are split or lumped by different organizations, each one of them fills a vital ecological niche. All of these birds help clean up the environment by eating carrion, which prevents the spread of diseases from old, rotting carcasses. Those diseases could affect other birds and wildlife, including humans, and could impact soil and waterways as well, contaminating crops and water sources with dangerous bacteria and infections."

2:10 Nature teaches self-perfection (to teach the soul to perfect itself), weeding-out the freaks and the weak and imperfections; only the healthy surviving; with natural-selection of the most perfect specimens, as partners, to keep the breed healthy, so that it will survive.
2:11 The natural harmony and balance, between the two sides of nature, i.e. animal and vegetation, living together and helping each other to survive, to teach the living with nature, helping it and each other. One, being more dependent upon the other; i.e. animals have to live with nature to survive, and are therefore more dependent on nature, than nature is on animals, but both help each other to survive; to teach that animals depend on nature, and nature depends on animals and God. Therefore animals should protect and live with nature and God, to ensure their own survival.
2:12 Nature was to supply the means for food, water and shelter, which make up three of the five basic necessities, or God given rights (human rights), the fourth, of equal importance, being freewill. Freewill (freedom) to decide, whether to continue to follow Satan, or to follow God’s guidance and learn to be good, without being forced, but instead, by loving encouragement, is of the UTMOST importance. http://thewayhomeorfacethefire.net
