Final answer:
Monoculture is the farming practice that does not support wildlife preservation as it reduces biodiversity and can lead to increased pest issues.
Step-by-step explanation:
The farming practice that does not promote the preservation of wildlife is c) Monoculture. Monoculture involves growing the same crop repeatedly on the same land, which depletes soil nutrients and may lead to an increase in plant pests. This practice can be detrimental to biodiversity, as it tends to reduce habitat complexity and welcomes the potential for significant pest outbreaks. In contrast, agroforestry encourages biodiversity by integrating trees with crops and livestock, organic farming avoids synthetic chemicals, benefiting the environment and wildlife, and integrated pest management (IPM) employs ecological pest control strategies, minimizing the need for harmful pesticides.
