Answer:
the government
Step-by-step explanation:
It certainly is the government as they deal in paper, conservation, lumber, and all sorts. In general, the government agencies are always the biggest, and hence the government is the most common employer for the foresters, and not various others mentioned as they are private and limited to resources. The paper companies cannot be as big as government, as government deals in all sectors, and hence they are the biggest employers, and also the most common employers.
