21.7 Scenario-Based Questions
Read the following scenario and answer the questions below.
Burning fossil fuels and their derivatives produces, among other things, harmful pollutants such
as particulates, acid rain-producing sulphur and nitrogen oxides, and carbon oxides. These air
pollutants threaten ecosystems all over the world, and high carbon dioxide levels contribute to
global warming. Furthermore, fossils fuels have a limited supply. The market price of fossil
fuels, especially crude oil, has continued to rise in recent years. Despite this, Canadians continue
to consume fossil fuels at alarming rates. We rely on fossil fuels for most of our energy needs. At
various times, the federal government has considered mandating higher fuel efficiency standards
for Canadian vehicles as a possible solution to this environmental energy crisis. Most auto
manufacturers, however, are opposed to the imposition of standards.
