The poem is about the way earth looks from different altitudes. It is divided into three parts. When the jet takes off and starts to climb up in the sky, you can have full height view of the city. The city grew as per its necessity and did not grow as per proper planning. It does not have any particular style. It even looked six inches from a certain height revealing its true structure. When the jet climbs higher up to about ten thousand feet, he could apprehend the fact that cities grew water resources. Water fulfilled the necessities like agriculture, transport, business and others. He found that valleys were populated which met the necessities of the people. When the jet went above six miles, there is more water than land on the earth. While appreciating the geographical niceties of our planet, the poet is unable to understand the tendency to build borders, to erect walls, to create fences. Then he reflected that people on earth selfish and narrow for they hate each other .He found the earth to be one but not the people living on this earth are divided for shallow reasons.
