ENVIRONMENTAL ISSUES, THEIR CAUSES, AND SUSTAINABILITY
1.1:LIVING MORE SUSTAINABLY
I. We face many environmental problems:
population growth
increasing resource use
destruction and degradation of wildlife habitats
premature extinction of plants and animals
poverty
pollution
II. We use natural resources to support our existence and lifestyles:
solar capital
natural capital
solar energy
III. An environmentally sustainable society is an ideal society that:
a. satisfies the needs of its people
b. without depleting or degrading its natural resources
c. and doing so, does not prevent current and future generations of humans and other species form meeting their basic needs.
1.2: POPULATION GROWTH, ECONOMIC GROWTH, ENVIRONMENTALLY SUSTAINABLE DEVELOPMENT, AND GLOBALIZATION
I. Linear growth makes less dramatic changes than exponential growth
II. The rule of 70 calculates doubling time: 70/percentage growth rate=doubling time
III. Economic growth is measured by an increase in:
Gross national product (GNP)
Gross domestic product (GDP)
Gross world product (GWP)
per capita GNP
IV. Developed countries (U.S., Canada, Japan, Australia, New Zealand, countries of Europe):
include 20% of the world's population (1.2 billion people)
have about 85% of the world's wealth and income
use about 88% of the world's natural resources
generate about 75% of the world's pollution and waste
V. Developing countries (in Africa, Asia, Latin America):
a. include 80% of the world's population (4.9 billion people)
have only about 15% of the world's wealth and income
c. use only 12% of the world's natural resources
VI. The Wealth Gap:
20% (1.2 billion) of the world's 6.1 billion people have a high per capita income.
25% (1.5 billion) have a moderate per capita income.
30% (1.8 billion) have a low per capita income of around $2-3 per day
25% (1.5 billion) have a very low per capita income of no more than $1 per day
VII. Each year, at least 10
