Question

what is the current approach to dealing with pests?
pest control
leaving pests unchecked
eradication of all pests
using pests as a food source

Explanation:

In pest management, the current common approach is pest control, which involves managing pest populations to reduce their negative impacts (like on crops, health, or property) rather than leaving them unchecked (which would let problems escalate), eradicating all pests (impractical as some pests have ecological roles or are too widespread), or using pests as a food source (not a standard or common approach for most pests).

A. pest control
