Human Activities Are Causing Many Stresses in Nearshore Estuarine Habitats

Human activities are causing many stresses in nearshore estuarine habitats, which are vital habitats for breeding and development of young marine fish and other animals.These stresses are occurring as a result of climate change, pollution, coastal construction, and a variety of other factors.Of the changes that occur in estuaries, which would not be considered a stress?

A) Increased salinity when drought decreases freshwater inputs
B) Increased acidity (decreased pH) as atmospheric CO₂ rises
C) Excess sediment due to nearshore dredging activities
D) A ban on a fishery that has been depleting fish stocks
E) Introduction of a non-native fish species that competes with native species
