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.

Different species have their different tricks for getting by. Human beings are smart, quick-moving and numerous. We're also pretty large, as mammals go. Sloths, on the other hand, take a whole different approach. Rather than compete for high-energy foods, they eat leaves, which nobody else much likes, because they don't have a lot of fuel to offer. To cope with their low-intensity diet, sloths have simplified and slowed the processes of life: They have half the muscle weight of a similarly sized monkey or cat, their metabolism is extremely slow, and they let other creatures do as much essential work as possible: Their fur is home to symbiotic bacteria and insects, and their stomachs are filled with other bacteria, processing those leaves.

As the name "sloth" suggests, humans don't really get this alien approach to life, but in the Central American jungles, five of the six living species of sloth are doing fine. Still, human indifference takes its toll: Sloths are killed by poachers, and regularly zapped on power lines.

When those deaths leave baby sloths behind, the orphans are sometimes taken to the Aviaros del Caribe sloth sanctuary in Costa Rica. There, according to Lucy Cooke, the "amphibian avenger," the animals are cared for by "the legendary sloth whisperer Judy Arroyo." Cooke shot this video there (there are more on her blog).

The videos show clearly that young sloths, despite their alien ways, certainly the "innate releasing mechanisms for affection" that Konrad Lorenz attributed to big heads, big eyes, small chins and other signs of juvenility. In other words, they're pretty cute. You could reflect on the evolutionary and psychological significance of this. Me, I just kicked back and went "aww."
