By Robert Olson, David Rejeski

We sit down on the doorstep of a number of revolutions in robot, genetic, info, and communique applied sciences, whose strong interactions promise social and environmental adjustments we're simply starting to comprehend. How do we count on their affects and confirm that those new applied sciences support circulation us in a extra sustainable path? Environmentalism and the applied sciences of day after today is a suite of essays via prime scientists, technologists, and thinkers that research the character of present technological adjustments, their environmental implications, and attainable ideas for the transition to a sustainable destiny. It deals a baseline figuring out of latest technological advancements, in addition to very important insights for relocating past business-as-usual through constructing extra anticipatory methods to environmental safety and extra entire recommendations for selling the transformation of technology.Among the members are Brad Allenby, David Bell, Steward model, Michael Braungart, Lester Brown, Joanne Ciulla, Denis Hayes, Hazel Henderson, Amory Lovins, William McDonough, Gary Marchant, David Ronfeldt, John Seely-Brown, Gus Speth, and Timothy Sturgeon.

New American cars average twenty-four miles per gallon (mpg), a twenty-year low. But an industrywide transition is on the horizon. Toyota’s Prius hybridelectric five-seater gets up to sixty mpg. A car fleet as efficient as the Prius would save twenty-five Arctic Refuges, but it’s just the start. , designed a competitively priced concept sport utility vehicle (SUV) as roomy, comfortable, and sporty as a Lexus RX-300—and as safe even if hit by one, although the Lexus is twice its weight. The car’s structure is made of ultralight carbon-fiber composite, which can absorb up to five times more crash energy per pound than steel.

One difference is size. The nanoparticles’ smaller size results in a greater importance for diffusive transport and greater potential for biouptake,8 and a unique surface chemistry. A second difference is structure. Engineered nanoparticles often display faceted surfaces that may affect their transport and reactivity. Toxicity Research While the field of nanotechnology is growing exponentially, a striking feature is the near absence of papers concerning the toxicology of these new materials. Casual observations from laboratories where scientists work with nanomaterials have not, thus far, suggested serious toxicity is- 48 environmental implications sues following nanomaterial exposure.

With this caveat, we believe it is very likely that applications of nanotechnology will lead to new means of reducing the production of wastes, using resources more sparingly, remediating industrial contamination, providing potable water, and improving the efficiency of energy production and use. In short, nanomaterials will be essential to achieving many of the goals articulated in the first section of this book. 41 new technologies As nanotechnology emerges as an important force behind these new environmental technologies, we are also presented with an unprecedented opportunity to consider the environmental implications of an emerging technology at its inception.
