Paragraph 1: The global demand for fresh water is rapidly increasing due to population growth, urbanization, and rising agricultural needs. Many regions, especially in developing countries, are facing severe shortages that threaten health and food security.

Paragraph 2: Traditional solutions such as building more dams or extracting groundwater are proving unsustainable, as they often cause environmental harm and deplete natural resources further. Scientists and policymakers now recognize the urgent need for alternative, sustainable water management practices.

Paragraph 3: Innovations such as water recycling, desalination, and efficient irrigation techniques offer hope, but require substantial investment and international cooperation. The passage emphasizes that securing a sustainable water future will depend on both technological advances and responsible global policy.
