actions have led to current prob- 
lems. Section II suggests additional 
basic causes, e.g., world population 
growth and the errors of technol- 
ogy. Section III concentrates on 
the atmosphere and climate rang- 
ing from types of pollutants, 
sources of air pollution and world 
climate to city weather and noise. 
Sections VI and V consider the 
effects on water and on land soil 
respectively. Topics on water in- 
clude types of contamination, 
eutrophication, oil pollution, and 
Soviet plans to reverse river flow. 
Surface mining, land subsidence, 
and effects of highways among 
others are discussed in Section V. 
Sections VI and IX emphasize 
the spread of organisms by man 
and man as maker of new plants 
and animals, and should be consid- 
ered in view of Sections VII and 
VIII which discuss destruction of 
vegetation and animals by man. 
With the reading of these sections, 
there is a full and startling realiz- 
ation that man, for all his intel- 
ligence and knowledge, is destroy- 
ing the earth’s lifeblood, and, 
since the beginning of civilization, 
has tended to destroy desirable 
plants and animals while uncon- 
sciously promoting less desirable 
ones. 
In the last section, Detwyler 
summarizes the major trends and 
common characteristics of environ- 
mental alteration and offers some 
solutions. A glossary of environ- 
mental terms is appended. The 
author has put it all together in an 
excellent volume that will give the 
reader ammunition for use against 
the anti-environmentalists.

DESIGN WITH NATURE 
by Ian McHarg 
Natural History Press (Doubleday)

Until recent years, most conserva- 
tion organizations were primarily 
concerned with greater land ac- 
quisitions for park and _ forest 
preserve purposes, via the problems 
caused by pesticides, the slaughter 
of wildlife by careless gunners, the 
litter problem along our highways, 
and the pollution of our rivers. 
Only in the last few years, have 
some environmental groups become 
aware of the great issue of urban 
planning and land zoning. Some 
haven’t reached that plateau yet. 
For those who have matured in the 
conservation field, Ian McHarg has 
written a classic in the area of 
urban planning and its impact upon 
the natural landscape. Originally 
published at $19.95, and written 
under a grant from the Conserva- 
tion Foundation, it should now 
reach a wider audience at a much 
lower price. It provides much
