Ebook Plants And Society

This introductory, one quarter/one-semester text takes a multidisciplinary approach to studying the relationship between plants and people. The authors strive to stimulate interest in plant science and encourage students to further their studies in botany. Also, by exposing students to society's historical connection to plants, Levetin and McMahon hope to instill a greater appreciation for the botanical world. Plants and Society covers basic principles of botany with strong emphasis on the economic aspects and social implications of plants and fungi.

This introductory text focuses on how humans interact with plants. The topics covered include: botanical principles; commercial products derived from plants; plants and human health; fungi; and plants and the environment.

A country's vision for developing renewable and sustainable energy resources is typically propelled by three important drivers – security, cost, and environmental impact. The U.S. currently accounts for a quarter of the world’s total oil consumption, with domestic demands necessitating – at an ever growing cost – a net import of more than 50% of the oil used in this country. At the same time, Brazil, because of its forward thinking on energy strategy, is today energy independent. As emerging economies around the world increase their petroleum use by large margins and as large fractions of that new consumption are necessarily supplied from unstable parts of the world, the inevitable repercussions on petroleum-driven economies will continue to escalate. In addition, there is an unequivocal imperative to take immediate and aggressive measures to reduce net greenhouse gas emissions by decreasing fossil fuel consumption and increasing our use of carbon-neutral or carbon-negative fuels as well as improving efficiency of fuel use. Economic growth and development worldwide depend increasingly on secure supplies of reliable, affordable, clean energy. Together with its counterpart societies, was convened the First Pan-American Congress on Plants and BioEnergy, which was held in June, 2008, in Mérida, Mexico. Sponsored by the American Society of Plant Biologists, this congress was designed to initiate Pan-American research collaborations in energy biosciences. At that congress, the organizational committee committed themselves to continue the meeting biennially, resulting in the 2nd Pan-American Congress on Plants and BioEnergy to be held with the endorsement of ASPB, July 6-10, 2010, in São Paulo, Brazil. Whereas the 1st congress covered a broad range of topics that bioenergy impacted, the second congress will focus more on the advances in plant biology: the genetic improvement of energy crop plants, their fit into regional environments, and the development of a sustainable energy agriculture.

The instant New York Times bestseller | A Washington Post Notable Book | One of NPR's Best Books of the Year “Expert storytelling . . . [Pollan] masterfully elevates a series of big questions about drugs, plants and humans that are likely to leave readers thinking in new ways.” —New York Times Book Review From #1 New York Times bestselling author Michael Pollan, a radical challenge to how we think about drugs, and an exploration into the powerful human attraction to psychoactive plants—and the equally powerful taboos. Of all the things humans rely on plants for—sustenance, beauty, medicine, fragrance, flavor, fiber—surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable. So, then, what is a “drug”? And why, for example, is making tea from the leaves of a tea plant acceptable, but making tea from a seed head of an opium poppy a federal crime? In This Is Your Mind on Plants, Michael Pollan dives deep into three plant drugs—opium, caffeine, and mescaline—and throws the fundamental strangeness, and arbitrariness, of our thinking about them into sharp relief. Exploring and participating in the cultures that have grown up around these drugs while consuming (or, in the case of caffeine, trying not to consume) them, Pollan reckons with the powerful human attraction to psychoactive plants. Why do we go to such great lengths to seek these shifts in consciousness, and then why do we fence that universal desire with laws and customs and fraught feelings? In this unique blend of history, science, and memoir, as well as participatory journalism, Pollan examines and experiences these plants from several very different angles and contexts, and shines a fresh light on a subject that is all too often treated reductively—as a drug, whether licit or illicit. But that is one of the least interesting things you can say about these plants, Pollan shows, for when we take them into our bodies and let them change our minds, we are engaging with nature in one of the most profound ways we can. Based in part on an essay published almost twenty-five years ago, this groundbreaking and singular consideration of psychoactive plants, and our attraction to them through time, holds up a mirror to our fundamental human needs and aspirations, the operations of our minds, and our entanglement with the natural world.
