How is the environment affected by desalination?

Desalination can negatively impact the environment in several ways. The process typically requires significant energy, often derived from fossil fuels, contributing to greenhouse gas emissions. Additionally, the discharge of highly concentrated brine and chemicals back into the ocean can harm marine ecosystems by altering salinity levels and affecting local wildlife. Furthermore, the intake of seawater can inadvertently trap and kill marine organisms, disrupting the ecosystem.
