A student is conducting research on the impact of humans on whooping crane populations in the North America. Which statement best supports the student’s claim that animals have been positively impacted by human intervention?(1 point)
Responses
A. Captive-bred whooping cranes have been introduced to natural environments.
B. In the 1800s, North America was home to over 1,000 whooping cranes.
C. Although the hunting of whooping cranes was criminalized, their numbers continued to decline.
D. In the early 1900s, the U.S. and Canada jointly signed a migratory bird treaty.
A. Captive-bred whooping cranes have been introduced to natural environments is the statement that best supports the student's claim that animals have been positively impacted by human intervention. This is because captive breeding programs have helped increase the population of whooping cranes and reintroduce them to their natural habitats, which is a direct result of human intervention.

The statement that best supports the student's claim that animals have been positively impacted by human intervention is:
A. Captive-bred whooping cranes have been introduced to natural environments.
To determine the statement that best supports the student's claim that animals have been positively impacted by human intervention, we need to analyze each option.
Option A states that "Captive-bred whooping cranes have been introduced to natural environments." This suggests that humans have intervened by breeding whooping cranes in captivity and then releasing them back into their natural habitats. This intervention can positively impact the whooping crane populations by increasing their numbers and helping to establish or restore populations in their natural environments.
Option B states that "In the 1800s, North America was home to over 1,000 whooping cranes." While this statement provides historical information about the population size of the whooping cranes in the 1800s, it does not directly address human intervention or how it has positively impacted the species.
Option C states that "Although the hunting of whooping cranes was criminalized, their numbers continued to decline." This statement implies that despite human efforts to protect the whooping cranes by criminalizing hunting, their population numbers still decreased. Therefore, this option does not support the claim that animals have been positively impacted by human intervention.
Option D states that "In the early 1900s, the U.S. and Canada jointly signed a migratory bird treaty." This treaty suggests that human intervention through international agreements aimed to protect migratory birds, including whooping cranes. The treaty could imply coordinated efforts to address threats to the species and their habitats, which could positively impact their populations over time.
Based on these explanations, option A, "Captive-bred whooping cranes have been introduced to natural environments," best supports the student's claim that animals have been positively impacted by human intervention.
