The Ecosystem Within

The microbiome is the term doctors use to describe the countless organisms each one of us carries in and on our bodies. In the last few years there’s been an explosion of research around how the gut microbiome is linked with our health. As Microbiologist Justin Sonnenburg tells producer Anna Lee, our microbiomes are like the control center of our bodies, affecting cognition, digestion, mood, and overall wellbeing. It turns out that that much of the current research into our gut microbiomes is best examined through the prism of environmental sciences. The challenges we face in the Anthropocene are the same challenges faced by the ecosystems we carry within.

The Evolution of Fire

Fire is evolving. The three necessary ingredients for fire – heat, fuel, and oxygen – each appeared at different times in geological history, meaning that fire wasn’t always around on Earth’s surface. Fire historian Steve Pyne describes the origin and evolution of fire over the past 420 millions years on Earth, including history’s true Promethean moment.

In a bonus segment, producer Mike Osborne chats with paleoclimate scientist Jud Partin about his new publication exploring the Younger Dryas, the most recent time in Earth’s history to experience abrupt climate change. Hear Jud describe what happened as Earth left the last ice age and why he’s still optimistic about abrupt climate change today.

What Went Wrong in Rondônia

In the late 1970′s, tens of thousands of Brazilian agricultural workers found themselves out of work due to technological advances on farms.  To combat the problem, the government, with help from the World Bank, set up a program to settle people into the rainforest and allow them to farm commercial crops.  The hitch? No one had tested the soil to see if it could support the crops being grown.  From there, the ambitious social and ecological experiment quickly turned into a nightmare of Hollywood proportions involving strife between ranchers and local tribes, clear cutting of the rainforest, and disease outbreaks of all kinds.  What can we learn from what went wrong in Rondônia?
