Showing results for "Extinction" in Earth Sciences

In The Last Days of the Dinosaurs, Riley Black walks listeners through what happened in the days, the years, the centuries and the million years after the impact, tracking the sweeping disruptions that overtook this one spot, and imagining what might have been happening elsewhere on the globe. Picture yourself in the Cretaceous period. It's a sunny afternoon in the Hell Creek of ancient Montana 66 million years ago. In a matter of hours, everything here will be wiped away.

The story of our environment may well be the most important story this century. We focus on issues facing people and the planet. Leading environmentalists, organizations, activists, and conservationists discuss meaningful ways to create a better and more sustainable future. Participants include EARTHDAY.ORG, Greenpeace, UNESCO World Heritage Centre, PETA, European Environment Agency, Peter Singer, 350.org, UNESCO Mahatma Gandhi Institute of Education for Peace and Sustainable Development, Citizens’ Climate Lobby, Earth System Governance Project, Forest Stewardship Council, Global Witness, ...

Palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and groundbreaking book, Steve Brusatte tells their—and our—story.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

Speaking to experts in fields as diverse as oil production and ecology, and visiting the places that have escaped recent human activity to discover how they have adapted to life without us, Alan Weisman paints an intriguing picture of the future of Earth. Exploring key concerns of our time, this absorbing thought experiment reveals a powerful - and surprising - picture of our planet's future.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

If you're a person who wants to know the secrets of humankind, nature, and evolution, then you're about to discover how to increase sensitivity to the problems of our planet right now! If you're serious about increase sensitivity to the problems of our planet and you really want to know the answers to these great life's questions, then you need to get a copy of A World without Humans: Pros & Cons of Our Eventual Extinction right now.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. For example, the current eon is called the Phanerozoic Eon, which means “visible life”. This is the eon in which multicellular life has evolved and thrived. Before this, life was microscopic (single cells).

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?
