A method for the collection of Aedes mosquito eggs is described whereby collection of mosquito eggs is used to monitor the intensity of egg deposition in urban and rural areas. The data is used to increase public awareness of the effect of human habitation and cultural practices on mosquito abundance.

This article relates the different views from specialists of the scientific expedition team for the exploration of the origin of sand-dust storms. They observed and examined on-site the ecological environment of places of origin for sand-dust storms, and tried to find out causes of sand-dust storm and what harm it can cause in the hope of…

Eco-Inquiry may be defined as a "whole science" curriculum that embeds hands-on science within thematic multi-dimensional learning experiences. Three modules for the upper elementary and middle grades focus on food webs, decomposition, and nutrient cycling. Each module lasts 4-7 weeks and may be used alone or in sequence. Student…

Ecology is the relationship between persons and their environment. A caring ecological relationship is dynamic, able to be affected by the internal environment of the person and by the people/animal/plant/object external environmental surround in which a person lives. This paper attempts to examine the nature of ecology and how to facilitate the…

The cities of the world are great engineering feats. From the earliest dwellings of man constructed out of the raw materials of the environment, man has used his ingenuity to work engineering wonders that improve the circumstances of human life. By engineering technological skills, human beings have altered the environment to suit varied…

Since the 1940's, Operation Bootstrap, an economic development program, has changed Puerto Rico from an undeveloped country to one with increasing energy demands, decreasing natural resources, and alarming environmental degredation. The Puerto Rican government is presently supporting high-energy industrial facilities without regard to…

A possible energy source is the utilization of solid waste as fuel for power production. Although this is only a partial solution to the problem, it will provide some energy while research continues. The economic feasibility of using wastes depends upon a greater amount of energy being produced than expended. (MA)

This collection of data and graphics were prepared in response to a request from the White House Energy Policy and Planning Staff. The focus of this document is on those environmental issues which will, in the near and midterm future, prove important to the rapid development of domestic energy resources. This report emphasizes coal because of its…

First presented at a United States Department of Agriculture (USDA) conference on renewable resources, this material includes information and discussion on critical issues, policies, and future alternatives for natural resources in the United States. (CO)

Third stream evaluation, the fusing of the ecological perspective with experimental or quasi-experimental evaluation design, is described. The ecological perspective necessitates that the conceptualization and analysis of a setting and the design of the study emphasize the interdependent relations among organisms, behavior and environment in…

This companion document to "Air Pollution Primer" is written for the nonexpert in air pollution; however, it does assume a familiarity with air pollution problems. This work is oriented toward providing the reader with knowledge about current and proposed air quality legislation and knowledge about available technology to meet these standards for…

To help urban, suburban, and rural tree owners know about air pollution's effects on trees and their tolerance and intolerance to pollutants, the USDA Forest Service has prepared this booklet. It answers the following questions about atmospheric pollution: Where does it come from? What can it do to trees? and What can we do about it? In addition,…

This two-part bibliography represents an effort to collect, condense, and organize the literature on the hydrocarbons in relation to air pollution. The approximately 2,300 documents abstracted are all included in the information storage and retrieval system of the National Air Pollution Control Administration's (NAPCA) Air Pollution Technical…
