Life Is Like That

The value of anything increases once it is needed. Waste is like that too. Look at what happen to empty fruit bunches (EFB) and other wastes in the oil palm industry. Its disposal at one time incurred cost, it is the reverse now as many products can be made out of EFB.
Something that works well tend to be forgotten. Its presence were felt only after it was lost. A case in point - electricity.
Something may be left idle, not used, or used only sparingly or selectively. Its importance suddenly rise once it is lost. Life is just like that, we value less what we have until it is taken away...
