TED-Ed: Are we running out of clean water? - Balsher Singh Sidhu

The video explores the paradox of water scarcity on a planet covered mostly by water. Despite the abundance of water, only a small fraction is accessible for human use, leading to global water scarcity issues. The water cycle ensures Earth doesn't run out of water, but uneven distribution and overconsumption, especially in agriculture, exacerbate the problem. The video highlights the need for sustainable practices in agriculture and personal lifestyle changes to conserve water. It emphasizes that while Earth won't run out of water, local shortages require global solutions.
