 Chapter 1-1
 Environmental Problems, Their Causes, and Sustainability
 Goals for today:
 Contrast more and less developed countries
 Identify resources as perpetual, renewable, and nonrenewable
 Describe sustainable yield and how it relates to environmental degradation
 What do you think are some of the major causes of our environmental problems today?
 The major causes of environmental problems are:
 Population growth
 Wasteful resource use
 Poverty
 Poor environmental accounting
 Ecological ignorance
 Economic growth provides people with goods/services.
 Measured in gross domestic product (GDP) market value of goods/services produced in a country for
use within a year. Requires more production/consumption.
 Economic development: using economic growth to improve living standards.
 The world’s countries economic status (more developed or less developed) are based on their degree of
industrialization and GDP.
 GDP per capita: means divide GDP by population
 In Latin, per capita means “per head”
 PPP- (purchasing power parity) relative value of currency
 Per capita GDP and PPP: figures out how much an average citizen can buy in that country
 The UN uses per capita GDP and PPP to categorize countries:
 3 Largest Economies by GDP
 1. U.S.
 2. China
 3. Japan
 Populations and Economy
 More Developed - highly industrialized
 18% population, 85% wealth, 88% resources, 75% pollution and waste
 Less Developed - low to moderate industrialization
 82% population, 15% wealth, 12% resources, 25% pollution and waste
 The gap between rich and poor has increased substantially.
 Global Outlook
 More Developed: U.S., Canada, Japan, Australia, New Zealand
 Less Developed: Countries in Africa, parts of Asia, Latin America
 More Developed countries have a stable/slow growing pop.
 "BRIC" countries: Brazil, Russia, India, and China. Difficult to categorize because of recent rapid economic
development.
 New topic…
 RESOURCES
 Inexhaustible: (perpetual) on a human time scale are continuous. (solar)
 Renewable: On a human time scale can be replenished rapidly (e.g. hours to several decades). (soil)
 Nonrenewable: On a human time scale are in fixed supply. (minerals)
 Which describes each item in the list below: Renewable, nonrenewable, perpetual
 Wind
 Fish
 Animals
 Fresh water
 Fresh air
 Fossil fuels
 Phosphates (non-metallic mineral)

Sustainable yield: using renewable resources without reducing its supply
Does sustainable yield apply to fossil fuels?
Environmental degradation: using more renewable resources than can be replaced
Give one example.
Check for Understanding:
1. What % of the world’s population lives in more developed countries?
2. Give 1 example of each resource type: perpetual, renewable, and nonrenewable
3. Although China has a high GDP, explain why its GDP per capita is so low.
