Human Ecology

Even if we've never had direct contact with one, we will have seen one, or at the very least, heard one. For those of us who live in the Western world, it is more than likely that one sleeps in our house, possibly even on our bed. I'm talking, of course, of the dog. Yet, this animal, which lives alongside 500 million of us all over the world - as an invaluable partner and a trusted confidant - presents us with one great unsolved mystery: how did this relationship - the most complex and enduring of any between human and animal - start in the first place?

America was built on white pine. From the 1600s through the Civil War and beyond, it was used to build the nation's ships and houses, barns, and bridges. Yet this popularity came at a cost: by the end of the nineteenth century, clear cutting had decimated much of America's white pine forests. In White Pine, ecologist and writer John Pastor takes listeners on walk through history, connecting the white pine forests that remain today to a legacy of destruction and renewal.

Geography GCSE AQA (8035) specification audiobook is essential listening for students, teachers and examiners as it contains chapters on all the topics covered in the GCSE specification. The physical geography section covers the challenge of natural hazards including tectonic and extreme weather events. The physical and human causes and effects of climate change are discussed and exemplified. The living world and ecosystems including hot deserts, cold environments and tropical rainforests are examined.

Mosquitoes are among the most notorious insects globally, infamous for their role as vectors of various deadly diseases. Yet, their existence is a complex interplay of detrimental and beneficial effects on both ecosystems and human societies.

This work is an examination of Darwin's theory of evolution, in particular his belief in competition as the driving force behind human development.

For the last three billion years or so, life on Earth was shaped by natural forces. Evolution tended to happen slowly, with species crafted across millennia. Then, a few hundred thousand years ago, along came a bolshie, big-brained, bipedal primate we now call Homo sapiens, and with that, the Earth’s natural history came to an abrupt end. We are now living through the post-natural phase, where humans have become the leading force shaping evolution. This audiobook considers the many ways that we’ve altered the DNA of living things and changed the fate of life on earth.

Although it is widely understood that energy and water are the world’s two most critical resources, their vital interconnections and vulnerabilities are less often recognized. This farsighted audiobook offers a new, holistic way of thinking about energy and water - a big picture approach that reveals the interdependence of the two resources, identifies the seriousness of the challenges, and lays out an optimistic approach with an array of solutions to ensure continuing sustainability.

The Digital Age was expected to usher in an era of clean production, an alternative to smokestack industries and their pollutants. But as environmental journalist Elizabeth Grossman reveals in this penetrating analysis of high tech manufacture and disposal, digital may be sleek, but it's anything but clean. Deep within every electronic device lie toxic materials that make up the bits and bytes, a complex thicket of lead, mercury, cadmium, plastics, and a host of other often harmful ingredients.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?
