We show that any co-orientable foliation of dimension two on a closed orientable 3-manifold with continuous tangent plane field can beC0-approximated by both positive and negative contact structures unless all leaves of the foliation are simply connected. As applications we deduce that the existence of a tautC0-foliation implies the existence of universally tight contact structures in the same homotopy class of plane fields and that a closed 3-manifold that admits a tautC0-foliation of codimension-1 is not anL-space in the sense of Heegaard-Floer homology.
