Former President, OLUSEGUN OBASANJO has asked Nigerian leaders to begin to put in place measures to prepare against population explosion.

He said Nigeria's population is becoming a liability due to its improper management, stressing that except there is urgent intervention, then the nation may be declared the third most populous nation in the world.

The former president stated this in Abeokuta, the Ogun State capital, during a mentoring session with students of some selected schools across the country tagged "raising the next wave of innovative leaders through entrepreneurship."

According to him, population management must come to the fore, especially in the face of the geometric population explosion without a corresponding socio-economic development.
