Câu 11: Read the passage and choose the correct answer for questions from 11 to 15.
Invasive alien species represent one of the greatest global threats to native biodiversity. An invasive organism is a plant or animal introduced into an ecosystem where it does not naturally belong, causing substantial ecological or economic damage. A prominent historical example occurred in the 1970s when fish farmers imported silver carp to North America to control algae in ponds. Unfortunately, during heavy floods, carp escaped into the Mississippi River basin. Because they consumed immense quantities of plankton, native paddlefish were deprived of nourishment, resulting in dramatic population declines. Similarly, the water hyacinth, native to South America, was brought to Lake Victoria in Africa as an ornamental plant. It proliferated rapidly, forming dense green mats that blocked sunlight, depleted dissolved oxygen, and devastated local fisheries. Conservationists urge governments to enact strict biosecurity laws to prohibit the unauthorized transport of alien wildlife.
