4. The United States consumes more than twice as much petroleum as any other country–19.5 million barrels per day in 2000. Japan, the second-largest consumer, only used 5.5 million barrels per day in the same year. The United States must import more than half of its petroleum from such OPEC countries as Saudi Arabia, Nigeria, and Venezuela. The United States also imports petroleum from Canada, Mexico, and the United Kingdom.

5. Resources • As people use up more and more nonrenewable resources, such as minerals and fossil fuels, scientists work on finding alternatives. • Hydroelectric power, which comes from water, and solar energy, which comes from the sun, are two alternatives to fossil fuels.

6. Economic Development • Natural resources are not distributed evenly over the earth. In developed countries only a small portion of the population works in agriculture. • In developing countries most of the people are subsistence farmers. • Industrialization has recently helped change economies in countries that once relied mostly on agriculture, such as China and Malaysia.

8. Certain militant groups in developing countries have used terrorism to counter the global influence of developed countries.

9. World Trade • Barriers to Trade Countries trade because of the unequal distribution of natural resources. • Each government tries to manage trade to benefit its people. • Countries often add tariffs to imported goods or set limits on how much can be imported. • When a country bans trade with another country for political or economic reasons, this action is called an embargo. 3.4 analyse factors that influence development within regions

11. Free Trade The World Trade Organization promotes free trade internationally. • The North American Free Trade Agreement (NAFTA) has removed trade barriers among the United States, Canada, and Mexico.

13. People and the Environment • Water and Land Pollution Water pollution includes oil spills from tankers, chemical and industrial waste from factories, fertilizers and chemicals used by farmers, animal wastes, and untreated sewage. • Land pollution results from unsanitary dumpsites, radioactive waste, and chemical waste.

14. Air Pollution The burning of fossil fuels by vehicles and industries causes air pollution. • Burning fuels give off gases and combine with precipitation to form acid rain, which can destroy whole forests. • The Fragile Ecosystem People can help protect the environment by treating water, preserving wilderness areas, recycling, and using hydroelectric or solar power instead of burning fossil fuels.
