befoulment การใช้

• We seem to have exhausted our appetite for harsh naturalism, for raw shock value and gratuitous befoulment of the screen.
• The litany of worries about overpopulation extends from food shortages to global warming; economic paralysis to warfare over resource shortages; pollution of water supplies and the oceans to denuding of forests; befoulment of air to decline in soil quality; greater traffic congestion to fewer educational opportunities.
