Motherly Love
Earth is a mother, because it provides every species with the possibility to grow (evolve) until that specie 'leaves' it's home and family and journeys outwards. If the child gets too rebellious, Mother puts him out of his psychosis. There is love, and resources for all, but when a child starts to offset the balance, to take away from the rest of his yet unborn/uncreated siblings; then that child is cast out, or mainly destroyed.
