Question

Describe the most significant restriction on access to potable water around the world.
in small paragraph

Answer 1

The single greatest restriction to access to potable water globally is inadequate infrastructure and services — a lack of reliable systems for sourcing, treating and distributing safe water, especially in poor, rural and peri‑urban areas. Even where water exists, weak governance, insufficient investment and unaffordability mean people rely on untreated or contaminated sources; this problem is then worsened by pollution, population growth and climate change, producing chronic shortages and stark inequalities in who can get safe drinking water.
