CURRENT ISSUES IN ENVIRONMENTAL SCIENCE
Catalog Description:
12 – Current Issues in Environmental Science
3 units
Identification of problems created by humans’ modification of their environment. Examination of human
population growth through history, resource use, and pollution. Introduction of fundamental concepts of
matter, energy, and ecology with emphasis on application of these concepts to a range of contemporary
environmental issues. May be offered in Distance Education delivery format. Ecology 10, 11, and 12 may
be combined for a maximum of 4 units. 3 hours

describe cultural changes, human population growth, and the impact humans have had on the
environment through history;
discuss major environmental challenges facing modern societies and explain why environmental
concerns have recently become so prominent;
describe the laws of energy and energy transformations by autotrophy and heterotrophy in food
chains;
describe the levels of organization of matter and recycling of matter;
compare ways that organisms interact within and between populations;
describe the process of natural selection and explain how it causes evolution and speciation to
occur;
explain how communities change through ecological succession;
explain how humans have increased the natural rate of extinction and compare methods used to
maintain biodiversity;
describe genetic engineering and explain how it can affect natural environments;
compare resource use in industrialized and less developed countries;
describe water, soil, mineral, food, land and air resources; list types and sources of pollution and
their impact on these resources;
list types of solid and hazardous wastes and pesticides; describe their impact on the
environment;
identify the causes and impact of global warming, acid deposition, and loss of the ozone layer;
compare the supply, cost, and environmental impact of fossil fuels, nuclear energy and
renewable sources of energy;
discuss sustainable use of resources.

CD-ROM
Internet - the internet will be used as follow:
The Blackboard website will be used to manage the course - assignments, updates, and current
events will be posted. Students will be directed to specific websites for virtual fieldtrips, research,
class assignments, etc. For example, when studying human population growth, students will be
directed to the United Nations Population fund websites where a press summary of the 2001
report on the state of the world population is located. The Blackboard website will be used for
student/instructor communication as well as student/student discussion of current issues.
