Which statement reflects a concern about biotechnology's impact on ecosystems?

• A. It always improves ecosystem health.
• B. It can be destructive to ecosystems and has many unknowns.
• C. It has no uncertain outcomes.
• D. It guarantees no gene transfer to wild relatives.

Answer: (B)

Biotechnology’s effect on ecosystems is best understood through risk and uncertainty. Ecosystems are interconnected networks where changes in one part can ripple through food webs, species interactions, and nutrient cycles in unpredictable ways. Engineered traits or organisms can move into wild populations via pollen, seeds, or other transfer pathways, potentially altering fitness and ecological balances. Because long-term, large-scale consequences are difficult to predict, it’s important to acknowledge both possible harms and the unknowns. That’s why the statement recognizing potential harm to ecosystems and many unknowns is the most accurate reflection of concern. It avoids certainty about outcomes and notes the real possibility of negative impacts. The other options are too absolute or optimistic: they claim universal improvement, no uncertainty, or no gene transfer, none of which align with how complex ecological systems interact with biotechnology.
