Today’s Outline

1. Today’s Outline • Announcements • Silent Spring discussion • next reading, Our Stolen Future • A Brief History ofEnvironmental Engineering

2. Announcements • Writing 1 revision due today • your revised file • OWL comments file • Writing 2 due next week • “Silent Spring book review” • submit first draft before class next week • Lastname Writing 2.doc • ideas…

3. Writing Assignment 2 • Silent Spring “book review” • Evaluate Rachel Carson’s writing style. Illustrate the writing style in two or three passages from the book. • Did Silent Spring change attitudes? Check the EPA’s pesticides web page and assess changes in the government’s attitude toward pesticides. • Examine the labels of some household pesticides and report on their hazards (using the EPA web site for information). • Rachel Carson makes the case that many pesticides are persistent and widespread – what does that mean for farms seeking the “organic” label? • You just read Silent Spring in 1962 – write a letter to your congressional representative to insist that something be done about the pesticides problem.
