A. Log and replant ¼ of the forest every 15 years.
Explanation:
As Sam utilizes simulation technology to demonstrate the greenhouse tactics that can maintain the woodlands and deliver an endurable source of food and wood, as it has already been given that the simulation needs a regeneration rate of 60 years.
The tactics that would allow the fast regeneration and longevity of the forest preserves would stand to log and replant one-fourth of the forest every fifteen years. Hence providing the most sustainable wood resource.
These forests were also known as coal forests, because they later all turned into coal. Hope this helps!
<span>True.
The scientific consensus is that global surface temperatures have increased in recent decades and that this has been predominantly anthropogenic (caused by humans) through the emissions of greenhouse gases.
"No scientific body of national or international standing disagrees with this view." (Oreskes, 2007)</span>
