Scarcity

This is an excerpt from Wikipedia.

Scarcity (also called paucity) is the problem of infinite human needs and wants, in a world of finite resources. In other words, society does not have sufficient productive resources to fulfill those wants and needs. Alternatively, scarcity implies that not all of society's goals can be pursued at the same time; trade-offs are made of one good against others. In an influential 1932 essay, Lionel Robbins defined economics as "the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses."

Scarcity. Most modern man believe in it. Is it really true? We have 6.6 billion population on earth. Is it true that the dear earth cannot support us? Really? Or have we screwed up the way we should be living? Or have we gone greedy?

John 10:10

The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
