◍ after a long time, s curve populations.
Answer: have birth rates equivalent to death rates
◍ after a long time, j curve populations.
Answer: have death rates higher than birth rates
◍ Regions of low biodiversity have, by definition.
Answer: few species
◍ why do curves in figure not follow paths shown?.
Answer: curved path will become straight, point of crisis changes
relationship between lines, after intersection curved line shouldnt exceed
straight line, exponential path cant continue indefinetely
◍ trends of all countries.
Answer: increased food production, lower mortality
◍ Are "cost-benefit" and "precautionary principle" approaches to
environmental regulation compatible? (2 marks).
Answer: Cost-Benefit Analysis means - Valuation of cost and benefits for
each year of project/policy; by aggregating and comparing costs and
benefits over the whole life of project policy. The precautionary principle
underlying sustainability dictates that in the face of high risk or insufficient
data, the priority should lie with ecosystem preservation rather than on
industrial development and market growth. They are not compatible because
unless the benefits outweigh the cost then it won't be done while the
, precautionary principle always supports helping the ecosystem.
◍ Describe the "Kuznets curve" and discuss a case in which this curve fails to
describe observed resource use.
Answer: There are limits to the Kuznets curve such effectiveness of
government regulation, the development of the economy, population levels.
Also developed countries tend to have less deforestation, but import meat
from countries who are having more deforestation.
◍ malthusianism.
Answer: population growth is limited by agricultural productivity and
resultts in inevitable mass poverty
◍ affluence.
Answer: average consumption of each person
◍ population is higher this year than last year (T/F).
Answer: True
◍ How have
U. S. minorities been differentially impacted by environmental degradation?
Cite at least two examples, and link them to course concepts, in your
answer.
Answer: Communities of color are more often located by a waste site than
white communities. They also tend to have higher exposure to air pollution
because of their location.
◍ Richest countries have highest birth rates T/F.
Answer: False
◍ What are "carbon footprints"? As applied to food, how are they different
from "food miles"?.
Answer: Carbon footprint measures the total amount of greenhouse gases
emitted. Food miles measure the distance that food travels from production
to consumption. If someone's food miles were big then their carbon footprint
would also be.
