Final answer:
The application of toxic chemicals for pest control should be managed by a licensed pest control operator due to the potential harm to humans and the environment and the required specialized training for safe handling.
Step-by-step explanation:
The individual responsible for the application of toxic chemicals used for pest destruction should be a licensed pest control operator. This is because the misuse of pesticides can have severe health and environmental consequences. Pesticides, by nature, can cause harm to humans, animals, and the environment as they are made to kill or adversely affect living organisms. Given the dangers associated with improper pesticide application, such as the potential for high-level long-term exposure and the complex risks involved in handling toxic substances, it is critical to ensure that those applying such chemicals are properly trained and certified.Pesticides serve an important role in agriculture and public health by managing pests that threaten crops and carry diseases. However, they also carry risks. Indiscriminate and excessive use of pesticides can lead to environmental damage, destruction of natural pest predators, the development of pesticide resistance, and health risks to humans involved in their application.In developed countries, growing awareness of these risks has led to stricter government regulations. In contrast, many developing countries face greater instances of pesticide poisoning due to weaker regulatory, health, and education systems, which makes the role of licensed professionals even more crucial.
