Book Description
A fascinating look at the historical relationship between environmental issues and scientific study, social attitudes, and public policy from the 17th century to the present. The Environment and Science: Social Impact and Interaction explores the history of how science investigates nature and how those studies both shape and are shaped by the social attitudes, philosophies, and politics of their times. It follows the changes in perceptions of the natural world and humankind's place in it from the European colonization of North America through the Industrial Revolution and westward expansion, to the rise of the consumer economy and the recent hardening of the ideological battle lines over environmental policy. Coverage includes the emergence of ecology as a science and conservation as a movement, the long history of conflicts between business interests and environmentalists, and the role of scientific studies in debates over atomic and nuclear power, pesticides, toxic emissions, and other human-made sources of environmental degradation.

Book Description
S2Pills of paraformaldehyde (trioxymethylene) are commonly used in tapholes in sugar maple trees (Acer saccharum Marsh.) to increase the yield of sap collected for making syrup and sugar (2, 4, 5, 8). The explanation offered for this increase in sap yield is that microorganisms in the tapholes (7) cause premature decline and stoppage of the sap flow (1, 6), but that paraformaldehyde increases sap yield by inhibiting their growth (2). But what happens to the tree? To determine the effects of paraformaldehyde on the tissues surrounding tapholes, and on the microorganisms in those tissues, sugar maple trees were dissected and studied. This paper is a report on that study.S3.
