Final answer:
Risk assessment in environmental policy-making is not always uncontroversial, as different stakeholders may have differing opinions on risks and appropriate actions to take.
Step-by-step explanation:
The statement that risk assessment depends upon scientific methods and is usually uncontroversial in environmental policy-making is not entirely true. While risk assessment does rely on scientific methods to evaluate potential risks and their consequences, it can still be a topic of debate and controversy in policy-making.
Risk assessment involves analyzing the likelihood of an event or process occurring and the potential consequences of that event. This analysis requires scientific data and research to assess the risks accurately.
However, different stakeholders may have differing opinions on the severity of certain risks, the appropriate actions to take, or the priority given to different risks. These disagreements and debates can make risk assessment a controversial aspect of environmental policy-making.
