Why is water an limited resource?

Water is considered a limited resource due to its uneven distribution across the globe, with some regions experiencing scarcity while others have abundant supplies. Additionally, factors such as population growth, pollution, climate change, and over-extraction from rivers and aquifers exacerbate water shortages. As demand increases and freshwater sources become depleted or contaminated, the sustainability of this vital resource is threatened, making effective management crucial for future generations.
