Compartmentalization of ideas will only weaken EVOKE

Keep power crisis at bay

Power is the issue
That scratch many a head,
Power is wanting
How can I go to bed?
Power to be tapped
From sun and the sea,
From electromagnetic waves
And from tree-
Power to be harnessed
From the cosmic ray;
I promise to keep
Power crisis at bay,
For future generation
I'll connect the power way.

The declining per capita water availability coupled with degrading land and water resources pose serious challenge to humanity and underscore the need for protection and efficient management. Multiple use of water is one option which has the potential to meet future demand for increasing productivity in the long term.

Direct falling rainwater, overland flow of runoff, lateral seepage flow (emerging within the watershed boundaries) can be stored in a reservoir formed due to…

Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
