Answer to Question 1

Five key modifications include irrigation, deforestation, construction of dams, desalination projects, and urbanization. Some of these include both positive and negative aspects. Irrigation, for example, helps expand agriculture into more arid locations, but contributes to the salinization of soils. The construction of dams provides hydroelectricity but has also contributed to the increased siltation of reservoirs and rivers.
