Which of the effects of irrigation on the world’s environment is a criticism of using reservoirs?

Answer 1

One of the criticisms of using reservoirs for irrigation is the negative impact on natural ecosystems and biodiversity. Reservoirs often involve the construction of large dams, which results in the flooding of vast areas of land. This process leads to the loss of vegetation, wildlife habitats, and even entire ecosystems. Additionally, the creation of reservoirs requires the diversion and alteration of river flows, which can further disrupt natural habitats and migratory patterns of aquatic species. These alterations in the environment can have long-lasting and irreversible consequences for biodiversity and ecological balance.
