Answer to #1

False. We can make a pretty good soil substitute, but true soil is made over time by natural processes

Answer to #2

False. A complete soil also contains organic matter

Answer to #3

Sustainability is a concept rather than a movement. Sustainability involves the principles of wise use, just as traditional
conservation did, but it adds the corollary that wise use should not totally exhaust a resource. The so-called
green movement is an offshoot of the sustainability idea, but it is an activist movement rather than a concept

Answer to #4

Conservation concentrates on the management of natural resources for the economic and political good of humanity,
in the long run. Preservation seeks to maintain something in its original state without the possibility of its
direct use by people

Answer to #5

The human population level has grown at an increasing rate (except briefly during the Black Plague) for the
past 8,000 years. There were an estimated 10 million humans in 6,000 B.C.E. compared to over 7 billion today.
Population levels are expected to level off in the next 250 years

All correct!
