Fresh Water

This article explores the crucial steps for sustainable fresh water use by analyzing the historical context of the Aral Sea, which was once the fourth-largest enclosed body of water and has decreased in size by approximately 25%, leading to a five-fold increase in salinity. It contrasts this with Lake Baikal, the largest freshwater body, which holds 20% of the world's supply. Additionally, we examine the impact of climate change on runoff in Puget Sound and the Georgia Basin, emphasizing the importance of sustainable practices driven by natural cycles and solar energy.
