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.

Canada To Restrict Certain Rodent Poisons; US May Follow

November 14, 2012, 6:17 PM

What's the Latest Development?

In response to studies showing that current varieties of anticoagulant rodenticides (ARs) build up in, and eventually kill, birds and other animals that feed on rodents, Canada will restrict outdoor household use of ARs to less-toxic versions starting January 1. In the US, the Environmental Protection Agency is looking at banning second-generation ARs from the consumer market and increasing the use of bromethalin, a neurotoxin.

What's the Big Idea?

The human blood thinner warfarin was originally developed as a rodenticide, but as a first-generation AR still in use today, it is considered less toxic because it doesn't accumulate in the bodies of predator animals. Second-generation ARs, on the other hand, were present in almost all of the dead owls and most of the dead hawks studied in and around Vancouver. Most users of these ARs are pest control professionals, who leave their products outside in permanent bait stations. One expert suggests that these be banned instead, that operators should use ARs only when necessary, and that customers should be warned of their environmental effects.
