Ocean acidification and overfishing threaten the marine food chain

Evidence

Humans have had a hand in the destruction of the maritime environment and are not merely passive blameless observers of its natural cycle. Carbon emissions are increasing the ocean’s acidity, threatening destruction of organisms at the base of the marine food chain that supports stocks of food fish (Chu, 2015; Kleypas et al., 2006). Such developments make interdependent environmentalism a lived reality, not just an abstract ethos. Massive overfishing to feed growing populations has already obliterated some fish species and has decreased the numbers of others. — Albert Bandura, Moral Disengagement, 2785
