Hydropower, or hydroelectric power, uses the kinetic energy of flowing water to generate electricity. Large dams are often constructed to create reservoirs, controlling water flow through turbines. While it provides a clean and reliable source of electricity, large-scale hydropower projects can have significant environmental consequences. These include altering river ecosystems, displacing local communities, and impacting fish migration patterns. What is a potential negative environmental impact of large-scale hydropower projects mentioned in the text?
A) Increased air pollution
B) Altering river ecosystems
C) Higher water consumption
D) Depletion of water resources
