Q

What is the difference between Biospheric Egalitarianism and Deep Ecology? Which one came first? Why did it change from one to other?

A

Biospheric Egalitarianism came first. B.E. stated that life has intrinsic value. It was changed into Deep Ecology because the idea that non-organic and lower life forms had self interest was controversial.

Q

Name four points of Deep Ecology.

A

Deep Ecology was redefined to say that (1) value is independent of human purposes, and that biodiversity is necessary and should not be damaged by human life activities. It states that the (2) human activities are worsening biodiversity. It further states that (3) policies and ideologies must be changed to appreciate life quality (happiness rather than GDP). Finally, it also says that (4) everyone has a personal responsibility to follow these points.

Q

20th c. Atmospheric Metal Flux in Central Park Lake: What was the method? How was the initial year known? How were the subsequent years known?

A

Take soil sample, assume constant rate of deposition, and analyze samples. The initial year was known to be 1858 because Central Park Lake is man-made. The subsequent year (1954) was known because of Cs-137, which was used during aboveground nuke testing.

56
Q

A

City burns trash at incinerators to provide steam energy, but because the incinerator is in private contractor’s hands with requirement of certain amount of trash burned per day, residential and commercial trash is burned.

65
Q

Incinerators in Detroit: Why did the incinerator become private in the first place?
