Heifer International works to ensure that the gift of each animal will eventually help an entire community to become self-sustaining. Animals such as goats, water buffalo and camels are "seven M" animals: they provide meat, milk, muscle, manure, money, materials and motivation. Once its immediate needs have been met, a family is free to sell any excess at market. Heifer International provides a breeding animal along with the gift animal so that it can produce offspring. Participating families are required to "pass on the gift", that is: they must give at least one of the female offspring to a neighbor who has undergone Heifer's training. In time, that neighbor will pass along one of the offspring of its animal, and so on.
So go on, give what you can, it's for a good cause. Check out the Team Bloggernacle website and click on the "General Team Donation" tab at the top to donate.
