Why might pesticides be banned or restricted in certain regions?

Pesticides may be banned or restricted in certain regions primarily due to concerns about their potential harm to human health and non-target organisms, which include beneficial insects, wildlife, and aquatic ecosystems. Regulatory bodies often evaluate the risks associated with pesticide use, and when evidence suggests that a pesticide poses significant risks—such as toxicity, persistence in the environment, or potential to harm endangered species—restrictions or bans may be implemented as a precautionary measure. This helps to safeguard public health and protects biodiversity, ensuring that ecosystems remain balanced and functional.

The other options—promoting agricultural productivity, simplifying pest management strategies, and increasing pesticide sales—do not accurately reflect the rationale for banning or restricting pesticide use. Concerns about health and environmental safety take precedence over any potential benefits related to productivity or sales.
