Evaluating Scientists' Arguments on Carbon Dioxide Effects

In a recent study, two groups of scientists conducted experiments on the effects of increased carbon dioxide levels in the atmosphere. The first group, led by Dr. Smith, argues that higher carbon dioxide concentrations significantly accelerate plant growth, particularly in staple crops such as wheat and corn. They suggest that this could lead to increased food production in the face of climate change.

In contrast, the second group, led by Dr. Johnson, contends that while initial plant growth may increase, the overall negative effects of higher carbon dioxide levels—such as drought stress, nutrient dilution, and potential changes in plant disease dynamics—could negate any positive impacts on crop yields. They stress the importance of considering environmental stressors when evaluating the benefits of enhanced carbon dioxide.

Based on the arguments presented by both groups of scientists, which of the following statements is most accurate?
