Thanks to the work of historians like Al
Crosby (The Columbian Exchange, Ecological Imperialism), most World
History textbooks now address the massive ecological consequences of contact
between the "old" and "new" worlds after 1492. Those of us who teach World
History often include at least one lecture about the highly unequal spread
of disease that marked this new relationship, not to mention the exchange
of edible plants, weeds, and animals that transformed both the Americas
and Afro-Eurasia. Beyond this attention to the 'American' or 'Columbian'
exchange, however, it seems safe to say that both texts and teachers of
World History tend to give ecological concerns rather short shrift. At best,
most of us treat the natural environment as a stage on which the real stuff
of history politics, cultural developments, warfare, intellectual movements happens.
John McNeil's Something New Under the Sun, however, helps us understand
that such an approach is just not good enough. Indeed, the environmental
changes wrought by contact in 1492 pale in comparison to those changes caused
by humans in the twentieth century. Now more than ever, the history (and
future) of humanity and the history (and future) of the planet are so tightly
interwoven that they are nearly incomprehensible in isolation. |

The reasons for this, according to McNeil,
lie in the massive environmental changes humans produced in virtually every
ecological sphere during the twentieth century changes that have affected
the planet's soils, air, waters, and its living plant and animal organisms.
The main engine for these changes was an "enormous surge of economic activity"
in the last century, which itself was fueled by rapid population growth
around the world and the exploitation and use of energy based on fossil
fuels (356). Each of these causes of environmental change were in turn caused
and sustained by social and political preferences that favored rapid industrialization,
production for national protection and war, and the accumulation of wealth
by the world's most powerful nations. |

The book is divided into two main sections,
preceded by an introductory chapter and followed by an epilogue. Part One,
"The Music of the Spheres," chronicles the astonishing changes humans have
caused to the lithosphere and pedosphere (chapter 2), the atmosphere (chapters
3 and 4), the hydrosphere (chapters 5 and 6), and the biosphere (chapters
7 and 8). Part Two, "Engines of Change," explores the human causes for these
changes in terms of population growth and urbanization (chapter 9), energy
use and economic expansion (chapter 10), and political and ideological regimes
(chapter 11). The epilogue, called "So What?", both recaps the book's major
arguments and seeks to identify the lasting significance of these changes
in terms of the human future. |

The net result of so much environmental change,
according to McNeil, is that our current situation represents "an extreme
deviation from durable, normal ecological circumstances" (326). For example,
in the twentieth century alone, humans likely used more energy than in all
of previous human history (15). Whereas natural forces (ie. wind, water)
were once responsible for the majority of soil erosion, in the twentieth
century that role was assumed by humans (35). Now, nearly a third of the
world's land surfaces suffer from soil degradation (48). But that's only
the tip of the iceberg. Human pollution of air and water by fossil fuel
combustion and chemical and organic contamination has resulted in the deaths
of millions of people, not to mention countless plants and animals. Forests
on the scale of the Indian subcontinent have disappeared (236). And although
some wealthy countries have taken impressive steps to clean their air and
water and to slow deforestation, these efforts have come at the cost of
increasing exploitation of natural resources in poor countries. Likewise,
while humans have had some successes in increasing food surpluses and fighting
both pests and microbes, these successes have come at the cost of decreasing
biodiversity and increasing pest and microbe resistance. In fact, we have
evidence that human actions have brought us to the verge of what may be
the sixth mass extinction of plants and animals in the history of the Earth
(262). As all of these examples indicate, McNeil hopes to show that our
current ecological situation shaped as it was by the historical processes,
choices, and preferences of the last century is fundamentally unsustainable
over the long term. More ominous still, it seems certain that many of the
consequences of environmental change wrought by humans in the twentieth
century (global warming, ozone depletion) will only become fully apparent
in the future. |

Something New Under the Sun is written
in a style that is accessible to teachers and college-level students at
all levels, and perhaps even to advanced high school students. As a result,
its possibilities for use in a World History classroom are several. At the
very least, teachers can use the book to provide background reading for
specific information about the ecological consequences of modern, industrial
economies in the twentieth century. Lectures about the social and political
consequences of the World Wars, the Cold War, or globalization, for example,
could be supplemented by attention to the ramifications each had for the
environment. Alternatively, teachers could use selections from the book
to augment textbook readings as a means of spurring discussion about the
relationship of humans to the environment. While any of the chapters could
work well for this purpose, chapter four ("The Atmosphere: Urban History")
is particularly suited to framing the long-term consequences of the Industrial
Revolution in a global, ecological context; while chapter eight ("The Biosphere:
Forests, Fish, and Invasions") makes an excellent complement to readings
and discussions about the effects of globalization in recent history.
Whether used as background reading or as a classroom text, teachers may
do well to consider McNeil's prediction that the colossal scale of human-induced
change to the natural environment in the last century may turn out to be
of more historical importance than anything else that occurred in the same
period more important, even, than "World War II, the communist enterprise,
the rise of mass literacy, the spread of democracy, or the growing emancipation
of women" (4). If nothing else, this idea may attract the interest of students
who might otherwise feel disengaged from the past, for this view of history
places their own futures squarely at stake. |
