As the Climate Warms, the Population Ranges of Organisms May

question 40

Multiple Choice

As the climate warms, the population ranges of organisms may shift to different areas that are cooler. However, as humans continue to fragment large tracts of land, species will face increasing challenges in adapting their ranges to new climates. For example, movement corridors may not be able to be built if the amount of land needed for a species' range is fragmented due to cities and roads. One alternative to creating movement corridors is called managed relocation. This requires physically moving species to cooler climates.
-What is a disadvantage of using managed relocation?

• A) Many vehicles will be needed to transport the species, so carbon dioxide (CO₂) emissions from the vehicles will cause an increase in global greenhouse gas levels.
• B) Governments will face long-term high fuel costs for the many vehicles that will be needed to move the species.
• C) Scientists may move the species to ranges where they will become invasive.
• D) Local economies will see an increase in jobs as many individuals will need to be hired to help move the species.
