Pesticides that degrade quickly in the environment are generally considered to be less harmful because their rapid breakdown reduces the duration of their potential impact on non-target organisms, ecosystems, and human health. When a pesticide has a short half-life, it means that it does not remain in the environment for a long time, leading to a lower risk of accumulation and toxicity over time.

This property is beneficial as it helps minimize environmental persistence and the likelihood of residue issues in soil, water, and living organisms. Additionally, pesticides that break down quickly may pose less risk of developing resistance in pest populations, further supporting their classification as less harmful compared to more persistent agents. In contrast, options that suggest higher hazard levels, suitability for long-term use, or persistent nature do not reflect the implications of rapid degradation in the environment.
