What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

World Now on Brink of 6th "Great Extinction"

What's the Latest?

A new study from noted biologist Stuart Pimm of Duke University has measured the rate at which species are currently going extinct and concludes that the plant is on the brink of a sixth massive extinction of plant and animal life. "Species of plants and animals are becoming extinct at least 1,000 times faster than they did before humans arrived on the scene," says the study, which also quantifies past rates of species extinction. Pimm identifies the number-one cause of rapid extinction as habitat loss. "Species are finding no place to live as more places are built up and altered by humans."

What's the Big Idea?

"Five times, a vast majority of the world's life has been snuffed out in what have been called mass extinctions, often associated with giant meteor strikes." Other major contributing factors to the current accelerated rate of extinction include invasive species crowding out native species, climate change affecting where species can survive, and overfishing. But the next great extinction does not have to occur. Whether the human species kills off the diversity on which the planetary ecosystem depends will be determined by our collective action.
