Changes

'''Desertification''' is the spread of [[desert]]-like conditions in [[arid]] or semi-arid areas, due to overgrazing, loss of agriculturally productive [[soil]]s, or climate change. Dredging - the practice of deepening an existing [[waterway]]; also, a technique used for collecting bottom-dwelling marine organisms (e.g., shellfish) or harvesting coral, often causing significant destruction of reef and [[ocean]]-floor [[ecosystem]]s.
