What is the potential drawback of focusing solely on aesthetic design?

Focusing solely on aesthetic design can lead to the neglect of ecological impacts, which is the primary reason why this answer is correct. When the emphasis is placed predominantly on the visual appeal of a landscape, it often disregards how the chosen plants and layout affect the local ecosystem. This oversight can result in choices that may not support wildlife, disrupt local flora and fauna, or fail to consider the environmental conditions that contribute to ecosystem health.

For example, using non-native plants that look attractive may provide little support to native species or local pollinators, which in turn impacts biodiversity. Additionally, such practices can contribute to drainage and soil erosion issues, adversely affecting water quality and further ecological balance.

In contrast, other potential drawbacks like increased maintenance requirements, limited plant choices, or higher initial costs do relate to aesthetic decisions but do not capture the broader implications on ecology in the same direct way as neglecting ecological impacts. These considerations often come into play when balancing aesthetics with practicality and sustainability, but they do not inherently stem from a singular focus on aesthetics.
