What is one reason why pesticide exposure can be hazardous?

Pesticide exposure can be hazardous primarily because it has the potential to cause both immediate and long-term health effects. Many pesticides are designed to be toxic to pests, and this toxicity can extend to non-target organisms, including humans and pets. When someone comes into contact with, ingests, or inhales pesticide residues, it can lead to acute symptoms like headaches, nausea, or skin irritation. Moreover, chronic exposure may increase the risk of more serious long-term health issues, such as cancer or neurological disorders. This dual possibility of health impacts underscores the importance of using pesticides responsibly and with appropriate safety measures.

The other options suggest aspects that are not accurate; for example, while some pesticides may contain natural ingredients, this does not inherently make them safe. Additionally, stating that pesticides are harmless to all living organisms is misleading since many pesticides are indeed harmful to non-target species. Lastly, while pesticides are intended to target specific pests, their effects can unintentionally impact beneficial organisms, demonstrating the need for careful use and consideration of broader ecological consequences.
