Question 1

Describe three reasons why government owned lands are important.

Accepted Answer

Government-owned lands provide vital ecosystem services that benefit humans living far from public forests,grasslands,deserts,and wetlands.These services include wildlife habitat,flood and erosion control,groundwater recharge,and the breakdown of pollutants.Undisturbed public lands are ecosystems that scientists use as a benchmark,or point of reference,to determine the impact of human activity.Geologists,zoologists,botanists,ecologists,and soil scientists are some of the scientists who use government-owned lands for scientific inquiry.These areas provide perfect settings for educational experiences not only in science but also in history,because they can be used to demonstrate the condition of the land when humans originally settled it.Public lands are important for their recreational value,providing places for hiking,swimming,boating,rafting,sport hunting,and fishing.Wild areas-forest-covered mountains,rolling prairies,barren deserts,and other undeveloped areas-are important to the human spirit.We can escape the tensions of the civilized world by retreating,even temporarily,to the solitude of natural areas.
