Desalination is the process of removing salt from seawater to provide freshwater, particularly in southern EU countries facing water shortages due to climate change. While it offers a drought-proof alternative, it is expensive, energy-intensive, and can harm marine ecosystems due to brine discharge. The EU classifies desalination as a 'green' investment under strict environmental conditions, emphasizing the need for renewable energy and sustainable practices. Despite its drawbacks, desalination is crucial for meeting water demands in certain regions. Teljes cikk (Euronews.com)
