Why is water pollution a concern if water is continuously cycled through Earth’s systems?

Answer 1

Water pollution is a concern because although water is continuously cycled through Earth's systems, the rate at which water is cleaned and replenished may not keep up with the rate at which it is polluted. Polluted water can have harmful effects on ecosystems and human health. Additionally, not all areas have access to clean water, and pollution can exacerbate water scarcity issues. Therefore, it is important to prevent and address water pollution to protect the environment and human health.
