Final answer:
The negative consequences of humans' use of excess water include increased runoff and depletion of water resources.
Step-by-step explanation:
Increasing use of excess water by humans can have negative consequences. One negative consequence is increased runoff, which can carry fertilizers from agricultural areas into water bodies. This can lead to water pollution and damage to aquatic ecosystems. Another negative consequence is the depletion of water resources, as excess water use can result in water not being recycled. When water is not recycled, it becomes unavailable for other uses or replenishing water sources.
