Samuel van Ooijen (23) is a Bio-Pharmaceutical MSc student at the University of Leiden. He has a high affinity with health care and conservation. The human-wildlife conflict is what drives him in his work for the foundation;

Raising the standard of living through healthcare and education opens up the possibility for families to rely less on the quantity of children and more on the quality of life per child. ”
