Final answer:
The boreal forest has significant economic and ecological value, serving as a vast carbon sink, contributing to climate regulation, and covering more area in Canada than all other forest types combined. Option D is incorrect as it has significant economic importance.
Step-by-step explanation:
The characteristic of the Boreal Forest that is not true is D) It has no significance to the Canadian economy. The Boreal Forest, or taiga, is significant to the Canadian economy and many others as it encompasses vast regions across Canada, Alaska, Russia, and northern Europe. The importance of these forests can be seen not only economically but also ecologically, as they are vast carbon sinks, help regulate climate through their albedo effect, and are rich in biodiversity despite lower species diversity than that of temperate and tropical forests. They are part of a forest complex that encircles the globe (A) and act as a global carbon sink as well as a carbon source (B), playing a crucial role in mitigating climate change. In Canada, the boreal forest area is indeed greater than all the other forest types combined (C), emphasizing its vastness and ecological importance.
