What might be a consequence of failing to implement green infrastructure?

Failing to implement green infrastructure can lead to higher runoff levels due to a lack of natural solutions that absorb and manage stormwater effectively. Green infrastructure, such as permeable pavements, rain gardens, and green roofs, is designed to mimic natural processes that allow water to soak into the ground rather than flow over impervious surfaces. Without these systems in place, rainwater cannot be absorbed effectively, resulting in increased surface runoff.

This higher volume of runoff can lead to various issues, including flooding, erosion, and the transport of pollutants from urban areas into local waterways. The absence of green infrastructure also prevents the natural filtration of stormwater, contributing to poorer water quality downstream. Hence, the importance of implementing green infrastructure lies in its ability to manage stormwater efficiently and sustainably, ultimately reducing runoff and its associated consequences.
