Final answer:
The statement that the comparative hazard of a pesticide is indicated by its specific precautionary signal is true. Signal words on labels communicate the pesticide's hazard level. The precautionary principle underscores the importance of these signals, especially when the full risks are not known.
Step-by-step explanation:
The comparative hazard of a pesticide is indicated by its specific precautionary signal. This statement is true. Pesticide labels contain signal words like 'Danger', 'Warning', or 'Caution' to indicate the level of toxicity and the potential hazard the pesticide poses to human health and the environment. The precautionary principle plays a key role in this, suggesting that one should proceed with caution when potential risks of a substance are not fully understood.
For instance, DDT is a pesticide that can be categorized as a C. Chemical agent, known for its adverse environmental effects, which were not immediately apparent upon its initial use. Thus, precautionary signals on pesticides are critical in guiding safe usage and handling, adding a layer of protection based on assumed risks.
There are also other factors to consider in human health, such as malnutrition, which is a significant contributor to child mortality, making it a severe health issue.
