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.

Amazon Deforestation Down 27 Percent, A New Low

November 28, 2012, 10:30 AM

What's the Latest Development?

The Brazilian government reports that, thanks to government action, the rate of deforestation in the Amazon rain forests is the lowest it's been since monitoring began 24 years ago. The 27-percent drop represents the difference between this year (up to July) and the previous 12 months. Overall, rates have been declining since 2004, and two states which had lost much of its forest experienced the largest drops: 31 and 44 percent.

What's the Big Idea?

Unfortunately, according to environment minister Izabella Teixeira, "[it's] the only good piece of environmental news." The bad news is that in that same year 4,600 square kilometers (just under 1,800 square miles) was still lost. Some Brazilian states saw an increase in deforestation, possibly due to less stringent enforcement of policies. Also, the large drop applies to a period prior to a recent change in the forest protection code, which environmentalists say could reverse the progress. The government disputes this, saying that the country is on target to meet its goal of reducing deforestation to 3,925 square kilometers (just over 1,500 square miles) per year by 2020. Large-scale deforestation continues to make Brazil one of the world's top contributors to greenhouse gas emissions.
