B. the appearance of lichens and mosses in an area where a glacier has recently melted away
Explanation:
Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.
Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.
According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.

b. Engineers should consider how much pollution their devices create because of how human health is affected.
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.
