What is the main reason that total forest area is increasing in many developed countries?
A. Technology is improving in the timber industry.
B. Natural forests have been replaced with planted and second-growth forests
C. Interest rates tend to be increasing
D. Falling timber prices make harvesting less profitable
D45. Trees in the forest cormpete for limited resources like space, sunlight and soil nutrients.
Some small plants like grasses and shrubs can't grow well therefore, population decreases.
