The state of São Paulo, Brazil, is one of the most densely populated and developed areas in South America. Such development is evident both in terms of industrialization and urbanization, as well as in agriculture, which is heavily based on sugar cane, Eucalyptus plantations and livestock. This intense land use has resulted in great alteration of the original land cover and fragmentation of natural ecosystems. For these reasons, it is almost a paradox that jaguar, a species that requires large areas of pristine forest to exist, is still found in some parts of the state of São Paulo. It is possible that wild animals could leave in coexistence with intense land use, or is it the case that such rare encounters with large wild animals in São Paulo will disappear in the near future?All ecologists are aware of the problems of habitat changes caused by humans, but it was not until recent years that researchers started to consider that the land used for production could also serve as an important habitat for many different kinds of wild species. This book is about this new approach to conservation. It also highlights the important role that sciences could and should have in this discussion in order to better understand the problems and propose possible solutions.

Are humans too good at adapting to the earth's natural environment? Every day, there is a net gain of more than 200,000 people on the planet-that's 146 a minute. Has our explosive population growth led to the mass extinction of countless species in the earth's plant and animal communities? Jeffrey K. McKee contends yes. The more people there are, the more we push aside wild plants and animals. In Sparing Nature, he explores the cause-and-effect relationship between these two trends, demonstrating that nature is too sparing to accommodate both a richly diverse living world and a rapidly expanding number of people. The author probes the past to find that humans and their ancestors have had negative impacts on species biodiversity for nearly two million years, and that extinction rates have accelerated since the origins of agriculture. Today entire ecosystems are in peril due to the relentless growth of the human population. McKee gives a guided tour of the interconnections within the living world to reveal the meaning and value of biodiversity, making the maze of technical research and scientific debates accessible to the general reader. Because it is clear that conservation cannot be left to the whims of changing human priorities, McKee takes the unabashedly neo-Malthusian position that the most effective measure to save earth's biodiversity is to slow the growth of human populations. By conscientiously becoming more responsible about our reproductive habits and our impact on other living beings, we can ensure that nature's services will make our lives not only supportable, but also sustainable for this century and beyond.
