Answer:
D. a school board, responding to fears that antibiotics and artificial growth hormones given to dairy cows xan harm children, mandates that schools only serve organic milk
Step-by-step explanation:
The precautionary principle is a concept that suggests taking preventive action in the face of uncertain risks to protect public health or the environment. It advocates for caution and erring on the side of safety when there are potential risks, even if scientific evidence is not yet conclusive.
In this scenario, the school board is implementing a proactive measure by mandating organic milk to avoid potential harm to children from antibiotics and artificial growth hormones. By choosing organic milk, which typically restricts the use of these substances, the school board is applying the precautionary principle by prioritizing the potential risks over the potential benefits of using non-organic milk.
