Why is making a conservation plan without understanding the cause of wildlife decline risky?

Correct answer: Because the problem may be identified wrongly

A conservation plan should begin by identifying why a species is declining. Different causes need different responses. If habitat loss is the problem, protecting or restoring habitat may be needed. If hunting is responsible, enforcement and community protection may be more important. If disease, pollution, invasive species, or lack of food is involved, those issues require other measures. Without this diagnosis, money and effort may be directed at the wrong problem.

Therefore option A is correct: the problem may be identified wrongly when its cause is not understood. The statement that every cause has the same solution is false, because conservation actions must match the cause. Data is useful for finding patterns, and understanding causes is not against the law; both are essential for effective planning.
