What is an example of a sustainable landscape practice?

Rainwater harvesting is a prime example of a sustainable landscape practice because it utilizes natural rainfall to provide water for irrigation and other needs, reducing dependency on municipal water supplies and protecting local water resources. This method can decrease runoff and erosion, contribute to stormwater management, and promote water conservation, which is essential for maintaining healthy ecosystems.

The practice aligns with sustainable principles by enhancing resource efficiency and promoting environmental stewardship. In contrast, the other options do not contribute positively to sustainability: synthetic fertilizers can lead to pollution and soil degradation, ignoring native plants might result in biodiversity loss and require more water resources, and planting grass in shaded areas often requires additional resources to maintain a healthy lawn under unfavorable conditions.
