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.

How to Replenish an Ecosystem

What's the Latest?

The Colorado River has reached the Gulf of California for the first time in 16 years, thanks to the combined efforts of the American and Mexican governments to restore the Colorado Delta after decades of damming and irrigation had caused it to dry. The reuniting of the river with its natural outlet is a result of a pulse flow beginning at the Hoover Dam and rolling through the Morelos Dam on the Arizona-Mexico border in March. The raising of the gates at Morelos allows shots of water to burst out, emulating the natural, undiverted springtime flow of the river.

What's the Big Idea?

The Colorado Delta last felt the touch of the river during the 1998 El Niño, but it's been several decades since the river flowed regularly though the Delta. As a result, the once-lush ecosystem had become nearly uninhabitable. Eight weeks of river flow coupled with the planting of cottonwoods, willows and mesquite by local conservationists has set the foundation for an unprecedented effort by the two nations to give back to a region from which they have taken so much. As the river carries sediment, nutrients, and freshwater back to the Delta, scientists hope habitats for the region's plants and wildlife can be resurrected. Although the amount of water currently flowing into the Delta is minuscule compared to the pre-dam era, the table has been set for a long-term revitalization that may serve as a model for future endeavors to rejuvenate parched ecosystems elsewhere.
