Answer:
The Labrador duck was a species of sea duck that was native to the coasts of North America. Unfortunately, this species is now extinct, and human actions were a major factor in its decline.
One of the main ways that human actions affected the carrying capacity of the habitat for Labrador ducks was through habitat destruction. As human populations grew, more and more land was converted for agricultural and urban use. This led to the destruction of the coastal wetlands and marshes that were the natural habitat of the Labrador duck. As the ducks lost their habitat, their population numbers began to decline.
Another factor that led to the decline of the Labrador duck was hunting. During the 19th century, there was a high demand for feathers to use in clothing and other items, and ducks were a popular target for hunters. The Labrador duck, with its distinctive white plumage, was particularly sought after. As a result, large numbers of these birds were killed for their feathers, which further contributed to their decline.
Overall, human actions such as habitat destruction and hunting had a significant impact on the carrying capacity of the habitat for Labrador ducks and contributed to their extinction.
