The Brother and Sister Relationship
Man as Brother
Gaia as Sister
Both Gaia and Man are equally important
They fight for lands; Gaia wants to keep the land for conservation, but Man wants to develop the land, and built many advanced structures.
For most of the times, Man will succeed in getting the pieces of land and use them for development
Man does not know the consequences of developing all the land and ignoring the conservation of the natural environment. Consequently, some of the lands are badly damaged, and Gaia becomes very upset.
In this case, Man realises his mistakes and set aside some lands for conservation. Both Gaia and Man will spend a nice and beautiful time together, despite the fact that they quarrel sometimes.
