The issue of accidental environmental contamination of homes and businesses has been of increasing concern. Actual costs to state and federal governments for relocation of persons and restoration of habitats have run into the tens of millions of dollars. In addition to these real costs, there have been more illusive costs to public health. These…

Innovations in teaching consumer ecology (environmental preservation vs. satisfaction of current demands), possible unit topics, causes and possible solutions for environmental problems, and teaching through filmstrips, audio tapes and games simulating real life decision-making situations are described. A seven-item bibliography accompanies the…

This document contains informational guidelines for identifying and evaluating the nature and extent of pollution from salt water intrusion.
