पृथ्वी की छिपी हुई जल संकट: उपग्रह द्वारा भ्रमण कराते हुए वैश्विक ताजा जल की कमी

A wave of new research using decades of NASA satellite data has uncovered a dramatic and unprecedented loss of freshwater across the planet. Scientists have found that over the past 20 years, Earth's continents are drying rapidly, with groundwater depletion and overpumping now major contributors to both water scarcity and rising sea levels. Four massive 'mega-drying' regions have emerged, mostly in the Northern Hemisphere, threatening food security, agriculture, and the stability of communities worldwide. The crisis is driven by a combination of climate change, increased evaporation, and unsustainable human extraction of groundwater. Experts warn that if current trends continue, billions could face severe water shortages, making urgent action to protect and manage freshwater resources critical.
