Question

Quizplus · Accepted Answer

Preventing the introduction of invasive species is the most effective way to limit their impact. Once they are established, controlling or eradicating them can be extremely difficult and expensive. Using pesticides or destroying them may harm native species or ecosystems as well. Importing natural predators can also have unintended consequences and may not be effective in controlling the invasive species. Altering their genes to die is not a feasible or ethical option.
