Logging is the main threat to old growth forests found in the northwestern united states. true or false?

True  it is logged because America needs
 more space so they cut down the forest and that is why it is the biggest problem 

That would be true. because logging is technically contributing to deforestation and thus causing a threat to old growth forests. the demand for resources is a factor in what causes this logging, therefore yes it is true.
