Notre planète va mal : réchauffement climatique, épuisement des ressources naturelles, pollutions des sols et de l'eau provoquées par les industries civiles et guerrières, disparité des richesses, malnutrition des hommes, taux d'extinction effarant des espèces vivantes, etc. La situation est-elle vraiment dramatique ? Que penser des thèses qui contestent ce pessimisme ?

Time rules our lives, woven into the very fabric of the universe-from the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day. Nothing so pervades our existence and yet is so difficult to explain. But now, in a series of 24 riveting lectures, you can grasp exactly why - as you take a mind-expanding journey through the past, present, and future, guided by a noted author and scientist.

In this course, we will discuss the moral aspects of human reproduction. We will discuss various influences on reproduction as well as the scientific advances in reproductive technology. At the end of this course we will not have arrived at answers to the various questions raised, but instead will have provided a base for us to consider the issues at hand and a desire to pursue more study in the important aspects of creating humans.

The history of Western civilization can be divided neatly into pre-Darwinian and post-Darwinian periods. Darwin's 1859 treatise, On the Origin of Species, was not the first work to propose that organisms had descended from other, earlier organisms and the mechanism of evolution it proposed remained controversial for years. Nevertheless, no biologist after 1859 could ignore Darwin's theories and few areas of thought and culture remained immune to their influence.

Best-selling author Michael Crichton talks with Audible's publisher Beth Anderson about his latest book, State of Fear. In this interview, Crichton explains how he came to rethink common wisdom about global warming. In the three year process of writing and researching the book, Crichton witnessed firsthand how difficult it can be to unearth scientific truth in a heavily politicized atmosphere. He warns against fanaticism and explains why a healthy skepticism is imperative in these fearful times.

Author Elizabeth Kolbert talks about how global warming is not a theory, but a fact. She speaks of the deep concern the scientific community has, and how other countries have begun to take steps to address this growing problem while America lags far behind. Field Notes from a Catastrophe is a compelling audiobook you'll want to listen to and share with others.
