It’s no secret that, although progress has been made, school lunches need help to become more nutritious and sustainable.

Half of U.S. farm workers are Hispanic, but few make it to leadership positions. A historically white non-profit, FFA, is creating equal education programs in California to increase leadership opportunities for minorities in agriculture.

The Colorado Correctional Industries is a program that positions inmates in different forms of labor such as making stuffed toys, farming fish, picking fruit, tending livestock, and creating crafts to be sold at grocery stores. The program makes inmates into taxpayers instead of tax burdens and offers skills that are useful for future employment once they leave prison.

In Colombia, traditional cattle pastures have caused soil degradation, deforestation, and desertification. To reconcile this, several thousand acres of land in Latin America have been transformed into a silvo-pastoral system of grazing and raising cattle with agro-forestry. The Colombia-based Center for Research in Sustainable Systems of Agriculture seeks to reduce pasture land by 26 million acres while increasing cattle numbers by 2019.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

Soil in Bangladesh is becoming increasingly saline and infertile due to climate change. Bangladeshi farmers have begun using a saline-tolerant rice seed in order to produce an abundant crop despite salty soil.
