The lack of access to healthy food has always been a problem for the financially unstable. Food stamps can now be used to buy fresh produce at farmers markets, but greater success could be achieved by getting grocery stores involved.

To decrease the nation's food waste, activists in Denmark showed the people that it was safe to buy and consume items that were very recently expired.

With child obesity on the rise, public school students have lacked the motivation and access to eat healthy food. Different programs around the country aim to improve student diet in public schools, including Real Eats for Academics and Life in Los Angeles and Cornell’s Smarter Lunchrooms Movement, by emailing nutrition report cards to parents, presenting the healthy food with aesthetic pleasure, and the arrangement of the food for access.

Organizations in Detroit are piloting a program to apply food stamp credits in grocery stores towards the purchase of nutritious produce, in order to increase access to healthy items. The initiative can also help the local economy prosper through increased promotion of locally grown produce.

America is the world’s main supplier of food aid to impoverished countries; however, food aid has the problems of long-distance transportation, the cost of the transportation and storage, and the navigation through dangerous zones.

Asian cities are over-crowded and many residences are kitchenless, causing families with children to consume unhealthy food from the street vendors.

The food carts are marketed at serving poor children a healthy meal.

The San Francisco Unified School District is piloting a collaboration with the design firm IDEO to re-imagine the school food system and help combat childhood obesity by better designing the space and the experience of how children eat, as much as the type of food they consume.

Ecological toilets that use natural composting to break down waste are simple to construct, waterless and are easy to fix. But as philanthropists are finding, getting these to those that need it most is harder than anticipated.
