True or False: Pesticides are mainly hazardous to humans.

The assertion that pesticides are mainly hazardous to humans is misleading. While it is true that pesticides can pose health risks to humans, they primarily serve the purpose of controlling pests in agricultural and horticultural settings. The primary concern of pesticide use involves the potential harm to non-target organisms, including beneficial insects, wildlife, and aquatic ecosystems. Thus, while humans must take precautions when handling pesticides to avoid exposure, the broader environmental impact of pesticides is a significant consideration.

Health risks to humans can arise from improper use or exposure during application, but with the correct safety measures and regulations in place, the risk can be mitigated. Therefore, it's important to recognize that the hazards posed by pesticides are not limited to humans and encompass a wider array of ecological and environmental factors.
