California Water Issues Practice Test 2025 – Complete Exam Prep Resource

Implementing rainwater harvesting systems is an example of a sustainable water practice because it effectively captures and utilizes rainfall for various purposes such as irrigation, landscape watering, and even household use. This method reduces reliance on traditional water sources, lowers water bills, and alleviates pressure on municipal water supplies, particularly in regions prone to drought, such as California.

In contrast, using bottled water is not sustainable due to the significant environmental impact associated with plastic production, transportation, and disposal. Continuously draining wetlands disrupts local ecosystems, reduces biodiversity, and affects water quality. Increasing reliance on groundwater can lead to depletion of aquifers, causing long-term sustainability issues for water resources. Therefore, rainwater harvesting represents a proactive approach to managing water resources responsibly while promoting environmental stewardship.
