One way to protect biodiversity is to set aside more wilderness land. humans are not allowed in these areas. a. true b. false

False, but it is also some what true.

It is true that one way to protect biodiversity is to set aside more wilderness land, but hikers and campers can visit such areas as long as they do not stay long. Scientists estimate that a wilderness area needs to be roughly at least 1,500 square miles in total, or it will be negatively impacted by affected by bad air, dirtly water, noise, and pollution from nearby human activities.

When dealing with the environment and ecosystems, it is important to establish a good balance between human activities and the conservation efforts. One good example of this is ecotourism. Some of the activities that fall under this catagory are hunting, fishing, off-road recreation, and even boating. Ecotourism is a billion-dollar industry, and without theses activities the funding to protect the wilderenss would be sparse if non-existant.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
