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.

The Big Idea for Monday, April 22, 2013

Has the impact of human behavior on the Earth's atmosphere created a new geological epoch? If so, we must shift gears radically, and that is what today's "Eco Warriors" -- people like Richard Branson, Michael Bloomerg, Stella McCartney and others -- are doing, forging innovative partnerships between science, business and activism to manage mankind's impact on the environment. 

In today's lesson we trace the modern environmental movement from its origins in Rachel Carson's seminal book Silent Spring to photographer Roger Moenk's project to rebrand the movement, I Am Eco Warrior

Along the way we also trace significant milestones that occurred since the first Earth Day was observed in 1970. We also consider the responsibility that corporations have in combating climate change. 

If we are to make significant changes in our relationship to the environment, Moenks argues we need new role models, and we need to support these "Eco Warriors" so they can "get to work and keep on raising the awareness and push corporations, governments, society at large to make better decisions."
