Planet Earth is a part of the Solar System, and has taken thousands and millions of years to become what it is today. From a hot mass of burning matter, the planet has slowly cooled outwards-in. The formation of water and land bodies have been purely governed by the changes Earth has been subjected to. The influencing factors like the gravitational pull of the Sun, moon and other bodies in the Solar System have been some of the noticeable external stimuli due to which we see Earth the way it is - 2/3's of water and 1/3's of land.
The movement of the seismic plates below the surface of the Earth has taken the planet through different stages; from the Ice Age to the age of Information and Technology. As we learnt in Physics, there is a Newton's law that states that "An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force". This applies well to our planet too. In the many years of mankind, apart from the external forces from the Solar System, our planet has increasingly seen yet another force - Force created by us Homo Sapiens.
Due to the technological advancements in the field of Civil Engineering, man built bridges and flyovers. Man has achieved extreme advancements in this field, that the world also saw the reclamation of land from natural water bodies (viz., seas, oceans and rivers) to create more land for human habitat. As a matter of fact, a good part of Mumbai (in Maharashtra, India) was claimed from the Arabian Sea. So is the Palm Jumeirah.
Due to natural equilibrium, the Earth has naturally been occupied by water for more than 2/3's it's surface area. As the first example, just imagine a pot of water that is filled to its brim. What will happen when you drop a stone into it? The water starts to overflow! This is precisely what we are forcing by claiming land from the natural water bodies!
Here is another example to explain another harsh action of mankind - Just imagine a pot filled with water till the brim and a piece of paper floating on the water surface. What will happen if you place a stone on top of this piece of paper? The paper sinks! This is what mankind is doing by building enormous buildings, skyscrapers, bridges and flyovers!
If we can treat the land (1/3rd of earth's surface) as a physical structure for a moment, we should also understand that this physical structure is also subjected to stresses and strains. Any physical structure has a point of failure / breakage. Applying strain above a certain limit is going to drive the physical structure (land) towards the point of breakage!
Having said that, here is my next question - "Can we make this better? Can we give Earth and mankind a little more time to exist? If so, How?" Here are my thoughts on how we can give ourselves and the generations to follow, a better and safer planet from an infrastructure perspective -
- Reduce the number of tall skyscrapers - Build smaller structures and use more of the earth's surface to build structures. Start building satellite towns and start expanding away from main cities
- Stop reclaming land from natural water bodies - Use what is available! Did you know that a very large part of Australia is uninhabited? Did you know that vast areas of land in India and China are uninhabited? This is the case in most countries!
- Stop breaking mountains to create artificial structures (viz., man-made caves, rivers, etc)
- Stop mass deforestation! There enough land available to build homes and offices - Let's leave the jungles to the flora and fauna
- Stop building dams to obstruct the natural flow of water....unless or until its absolutely essential
Let us make the world a better and safer place to live. Peace..
