Contemporary environmental sensitivity has characterized for decades the emerging culture in the developed world. It is not yet mainstream in influencing behavior at a global level, as the growing environmental impact of consumerism testifies particularly to it. Present day environmental sensitivity seems somehow at odds with Christianism, charged for decades alongside Judaism with major responsibility in the environmental crisis. This paper explains and discusses on seven interlinked aspects of the environmental value amply recognized across environmentalism. In examining them, Christian environmentalism learns particularly some demands of the Christian vocation that may remain neglected and demand a moral conversion both of Christians and of no non-Christians and non-believers. In accepting this demand, the Christian discerns the life-giving presence of Christ in many traits of the environmental sensitivity and culture. This encounter offers grounds for a reciprocal understanding and enrichment of Christians and non-believers or non-Christians, towards the attainment of a wider and deeper respect of environmental and human shared values.
