Natural resources

-
Hey there,
Exams are slowly creeping closer and closer and I just started revision.
I am going to try kill two birds with the same stone here.. Revise and add a new blog post..
This post is not for the weak hearted.. Hard core Material Worlds stuff.. :)

Natural resources- These are the products of ecological, biological and geological processes that satisfy human needs. This term is widely used in human geography. and signifies the functional utility that is attached to certain elements of the natural world by various social groups.
Eg: Coal, Water

They may be important for several reasons:
  1. Direct consumption
  2. Important for the maintenance of life or economic production (Eg Maintenance of Biodiversity)
  3. Ethical, Aesthetic, Ecological Values attached to it
These natural resources, you would be 'happy' to know (if you haven't dozed off yet) into sub categories on the basis of several grounds.

  • Biotic and Abiotic resources: By far the easiest one to classify. As you already might now, Biotic resources are those which are living (Flora and fauna) and have the power of reproduction. Abiotic, on the other hand, are the productive (water and minerals, for example) and ambient (solar radiation) resources. Some of the abiotic ones can regenerate over a period of time, eg gravel and groundwater.
  • Based on the Spatial Extent of resources: The 'Ubiquities' that are those which are found anywhere on earth, such as nitrogen and oxygen. The 'localised' ones which are restrained in geography and frequency of occurrence. This may also be the case of a certain level of quality, For eg aluminium is found in several parts of the world, but the good quality usable aluminium might be restricted to only certain regions.
  • Based on whether or not they can regenerate and renew their availability in time: The 'Stock', basically the non renewables, once used they cannot unfortunately be replenished.. For eg: Oil. The 'Flow' on the other hand, are renewable.
  • Based on the mobility and how easily they can be captured: Fixed resources and Fugitives(the availability of these not controlled by human made boundaries and hence difficult to enforce exclusive ownership).

Moths to a flame

The addictive intoxication of nostalgia, Leads many to the path of doom. Time and time again, they succumb, Flying into the Flame. Like moths, their insides burn, And their wings sing. They fall befuddled, Wondering where they went wrong.

Dreaming about the dreaming spires

From the moment my father handed me that first book which I hungrily demolished in a matter of days, it has been a dream, to study amidst its dreamy spires and brush shoulders with its legendary figures. Visiting King's Cross and the highlands of Scotland only served to cement my decision further. No prizes for guessing the Institute of Interest then. Attending a mundane university with the rest of the muggles holds no promise or excitement for someone like me, who is convinced that it is in the magical school of Hogwarts where I belong. Over the years, with each book of the series devoured, I have admired afar the interesting curriculum offered at Hogwarts. The sheer variety of interesting subjects offered is reason enough for me to pack my bags and zip my way through to Platform 9 3/4 and board the next Hogwarts Express to Hogwarts. Astronomy, Dark Arts, Flying, Potions, Transfiguration and Charms are so much more indispensable to human existence than the ubiquitous Biolo

love at first sight, they say

 At first a non believer, all Love took was a glance and talk at the local cafe, He walked into my life like a tornado and nothing remained the same. Flowers blossomed, birds chirped and the once lonely heart beat back to life. Years down the road, over some kathi rolls and coffee, We plan our happily ever after and laugh with glee.
