Explanation:

Anthropocentrism, is a worldview that argues that humans are more important and significant that any other entities or species in the world. This view point argues that humans possess greater intrinsic values compared to other species; this viewpoint sees humans as superiors while other entities are inferior to them and hence can be used by humans for their own benefit.

Therefore the anthropocentric viewpoint as it relates to environmental ethics implies that engineers should consider how much pollution their devices create because of how human health is affected.
