I first heard about Heifer International several years ago when our church handed out small plastic ark banks to the children. The idea was for each child to fill the bank and return it as a donation to to the Heifer project. Heifer's mission is to end hunger. They work with communities all around the world providing livestock and training to small-scale farmers and communities worldwide.
Heifer has a central office in Little Rock. Yesterday we went on a tour of the Heifer Green Building. It is one of the most "earth friendly" buildings I have ever visited. They offer free tours twice daily during the week. You can learn about what Heifer International does and even more about why the building is designed in such an unusual way by going on the tour.
As you look at the building you can tell that it is very long and narrow with many window. That design allows the building to be lit primary with sunlight. The building also captures rain water which it utilizes for the toilets, heating and cooling.
