The influential book of Mike Davis is on the enormous growth of settlements all over the world.The overall purpose of the book is to provide a statement to the people that they are a planet of slums.
The universe comprises of several millions of galaxies and each galaxy is a conglomeration of stars at different stages in their life cycle.
Our own sun is one such star, around which revolve planets and other debris.
The main argument presented by author is about negative aspects and roots of global slums.
At start, the rising mega slums are being neglected by Davis from core program of political considerations.
Places that reside along the equator experience only two seasons, one wet and one dry, because they get an immense amount of direct sun exposure.
This is because of the way the Earth is positioned; this tilt of the earth's axis is also what is directly responsible for the four seasons of the most northern and the most southern climates.
Planet Earth: Disc There are cycles to almost everything in nature and this is shown in the first DVD of the Planet Earth series; "From Pole to Pole/ Mountains/ Fresh Water".
The seasons are a cycle that is brought up continuously throughout every section, whether it is two seasons or four depends on the location.
But, it can be realized from latter part of the book that author tries to provide vivid description of the cause of urban poverty on global scale.
The author is looking in case of historical context and global scale rather than existing conditions and local governments (Davis 38).
