Final answer:
All the options listed (A: Source of wealth and employment, B: Natural habitat, C: Carbon sink) are indeed benefits of the boreal forest. The boreal forest serves as a carbon sink, supports biodiversity, and provides economic benefits through jobs and resources.
Step-by-step explanation:
When looking at the various benefits of the boreal forest, we can see that options A (Source of wealth and employment), B (Natural habitat), and C (Carbon sink) all describe true benefits. Forests, and specifically boreal forests, provide critical ecosystem services such as carbon storage, habitat for wildlife, and resources for economic activities. Carbon sink refers to the forest's ability to absorb and store carbon dioxide, thus reducing the amount of CO2 in the atmosphere and mitigating climate change.
Boreal forests are also biologically rich, serving as a home to numerous species and supporting biodiversity. They offer a place for wildlife to live and thrive, which is another significant benefit. Moreover, forests contribute to the global economy through jobs and resources, making them an important source of wealth and employment.
The options provided in the question are therefore all true benefits, so the correct answer to the question, 'Which of the following reasons is NOT a benefit of the boreal forest?' would be D. 'All of the above are benefits.'
