Recitation classes for the environmental science course will begin the week of April 4th. The classes will cover material from the textbook as well as journals and news sources. Exams will be based primarily on the material discussed in lectures. Students have the option to complete a current events project for 50 extra credit points, which is equivalent to 10% of the final grade.

6. Environmental Science is the
interdisciplinary study of humanity’s
relationship with other organisms and
Earth. It combines many disciplines
such biology, geography, chemistry,
geology, physics, economics,
sociology, anthropology, resource
management, agriculture, law, politics,
engineering, and ethics.
Physical Environment consists of the
incoming radiant energy of the sun, air, Global Environmental Awakening
water, and soil, which is required for Occurred in the 1960s
life on Earth. 1.Rachel Carson’s book “The
Silent Spring”
Biological Environment 2.Major environmental
encompasses the organic catastrophes including Lake
components, organisms (including Erie, California oil spills, threats
humans) and their relationships on of extinctions whales,
Earth. elephants, birds.

7. DTT is a persistent
organic pollutant
DDT
dichlorodiphenyltrichloroethane
An organochloride first synthesized in
1874
Insecticidal properties not discovered
until 1939
Effective control of malaria and typhus
during WWII
bioaccumulation
Nobel Prize in Medicine 1948 to Paul
Mueller for discovery that DDT could
be used as pesticide
Toxin, carcinogen, mutagenic

8. 1950-1980 DDT used worldwide in
agriculture as pesticide
U.S. banned its use in 1972
The book “Silent Spring” by Rachel
Carson brought issue to public view
arguing that pesticides, including DDT,
were poisoning wildlife, environment and
humans.

Several geologists believe that a Ohio hazardous-waste well
triggered a series of earthquakes near Ashtabula from 1987
through 2001. Waste was injected into the well from 1986 through
1992. Apparently what was happening was the fluid was
encountering faults at near-failure condition," said Michael Hansen,
the state seismologist. A team of Columbia University geologists
concluded that the well caused the quakes.
