What is one environmental concern associated with large water projects?

Large water projects can significantly reshape landscapes and ecosystems, leading to notable impacts on local wildlife habitats. When sizable water infrastructure, such as dams or reservoirs, is constructed, it often floods areas that were previously home to various plant and animal species. This inundation can destroy existing habitats, displace wildlife, and disrupt migration patterns. Additionally, changes in water flow, temperature, and sediment transport can alter the ecological balance, putting further stress on native species and potentially leading to declines in biodiversity.

The construction and operation of these projects may also involve the introduction of non-native species, which can outcompete local flora and fauna, further endangering local wildlife. Thus, the environmental concern tied to the effects on wildlife habitats is a crucial consideration in the planning and execution of large water projects.
