More than half of the world's lakes have shrunk in the past 30 years.

Since the early 1990s, approximately 53% of the world's lakes have shrunk due to industrialization, the climate crisis, population growth and the construction of waterworks. This can lead to problems with drinking water and water supply for agriculture and energy facilities. The world's lakes were losing water at a rate of 22 gigatonnes per year. Reservoirs in Central Asia and the Middle East, as well as in Finland, Canada, Australia, and Brazil suffered the most.
