      Question:  Water composition of human body in relation to water security

The human body is about  60% water, necessitating a continuous intake to survive, which directly links to the critical issue of water security. The body cannot store large water quantities, so a daily supply of adequate, safe water is a fundamental human need and a key component of public health and global stability.  Physiological Need: The body requires a constant intake of water (around 2-3 liters daily for adults) to maintain essential functions like temperature regulation, waste removal, and cellular health. Dehydration impairs cognitive function and physical performance. No Internal Production: Humans lack the capacity to produce enough water internally for homeostasis, making external water sources vital. Vulnerability: This daily requirement, coupled with the body's inability to store reserves, means that communities without reliable access to safe, affordable water are highly vulnerable to health crises, disease (like cholera from contaminated sources), and economic decline. Global Impact: Water scarcity, driven by population growth, climate change, and poor management, directly threatens human health and well-being by making this essential resource unreliable.
