The World is the planet Earth and all life upon it, including Human civilization.

In a philosophical context, the World is the whole of the physical Universe.

In a theological context, the World is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred.

The ‘end of the World’ refers to scenarios of the final end of Human history, often in religious contexts.

The World Population is the total number of Human‘s currently living.

As of March 2017, it was estimated at 7.49 billion. The United Nations estimates it will further increase to 11.2 billion in the year 2100.

Scientists have argued that the current World Population expansion and accompanying increase in resource consumption threatens the World‘s ecosystem.
