A crash course in changing the world.
"Innovation (often) comes from constraint (If you’ve got very few resources, you’re forced to be very creative in using and reusing them.)" -Ethan Zuckerman
It has always been a personal belief of mine that when the need for something is greatest, it comes about. It is shown to be true by the human body during times of great duress we get a surge of strength and courage to help combat our antagonist.
I believe the same concept holds true in society. When a community needs something, and it seems as though they have nothing, wheels begin to turn in the minds of the locals. Next thing you know there are bamboo sticks, bike chains, make shift blankets and old T-Shirts put together with soft clay and shoe laces all put into a pile that oddly resembles a Wind Mill to grind grain or move water. To us in the modern world this doesn't seem like innovation, but these people took what appeared to be nothing and transformed it into something (to them) that was NEW and invaulable.
This is all because a need that counld not be satisfied by existing means reasonably presented itself. The human mind took it fom there.
