What is a significant consequence of over-extraction of water resources?

Over-extraction of water resources leads to decreased water quality and availability, which is a significant consequence of this practice. When water is extracted beyond the sustainable limits, the natural replenishment process cannot keep up, leading to lowered water tables and reduced flow in rivers and streams. This can result in various ecological issues such as habitat destruction, loss of aquatic life, and degradation of water bodies.

Furthermore, as the quantity of water diminishes, the remaining water can become more concentrated with pollutants and contaminants, thus degrading its overall quality. This has direct implications for both human consumption and ecosystem health, as lower water availability can lead to stressed environments and increased competition for resources among ecosystems. Thus, the over-extraction of water significantly impacts both the environment and communities that rely on these water sources.
