At the Fujitsu factory in Japan, a significant decline in demand for semiconductor computer chips meant the company had large empty factory space sitting unused. A new business approach allowed them to dually address both the need to evolve their business model with a global decline of viable agricultural space needed to grow the world's food.

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

The Holberton School, a San Francisco "start-up" university with a two-year curriculum, aims to provide an affordable and estimable computer science education while removing barriers to knowledge -- age, gender, ethnicity, past professional life -- typically confronted by minority and low-income students across the nation.

Most of the communities didn't have regular access to rupees to help sustain their solar water pump micro-enterprises - what they did have, however, were goats.

Teens selling water on the sweltering streets of Atlanta are typically dealt with by police officers who often crack down on "unpermitted sales of water by youth." In a new approach, city officials convened a council to offer alternatives to police action and suggested ways to promote and develop the entrepreneurial spirit in teens through a variety of programs. The council looked to a similar program in Baltimore that re-engaged windshield-washing teens in school and re-directed others to full-time jobs.
