INCREASING THE REVENUE
-------------------------------------

I am particularly focusing to airliner.In spite of flights filled to capacity,there is not marked profits.
One reason is that the cost-reduction could not go further, as the management has been effectively enforcing the same.Everytime,the management grapples with stiff resistance from the employees,if they are negotiated on reduced pay or benefits.
To generate revenue without a threat to either employees or general public, i suggest displaying commercials in the T.V.screens installed inside the aircrafts.The advertisers ,as and when they launch their services/products would have the benefit of effective propaganda.
If mutually agreed, the new products could be displayed or sold during travel-time.Depending on the volume of traffic,the cost of ads. could be worked out.

FLOOD & FAMINE
-------------------------

Turn the pages of your daily.Not a day passes off without a report about these ,happening in one part or the other.The news about flood/famine affected places narrate harrowing tab of the people -in -anguish..Most of the times, we are caught napping.Before the rush of food &medicine,we are but the phlegmatic onlookers to more chaos and ordeal.
From the previous statistics if the prone areas are identified,preventive measures can be envisaged in order to store the life-saving drugs,baby's food,dairy products ,milk powder besides medicine (to prevent epidemics )and clothes at a convenient but close proximity.
Thus major catastrophe could be staved off.

The need of the hour

Imagine a world--peace everywhere.No aggression or intransigence by breakaway groups or nations.
Yet,we witness the opposite.
What,as individuals,can we  can do to convert the war-ridden world into a paradise?
I believe that if the people   around the globe--a big chunk are peace-loving--are drawn to form a mass movement,we can save the world from the clutches of power -mongers.
Why not we act now?By enlisting support from all such persons ,we could pose a terror to erring Heads of Governments or Nations .
In my opinion, two factors are detrimental to our problems. The first is the interference of religion in the politics.If this is curbed or totally sidelined, there will be progress and overall peace . Another pulling factor is the greed of individuals who wield power out of ill-gotten wealth . This is distinct in developing & under-developed countries.
Thus a war is be launched , not by armed forces but by combined mental strength of the people to weed out the tyrants from the society in  every corner of the globe .
A new era will then be born .
