The main problem with domestication is that only a select few genetic combinations and species are selected to breed. This causes genetic erosion within species of stock animals. This makes
stock animals vulnerable to disease and environmental conditions that are not common to the normal stock animal such as drought. For example, back in the 1970s most of the cattle in Africa were of an imported breed. Local breeds of African cattle had almost completely been replaced by these imports, however, a few small herds remained. When a 7-year drought hit the continent most of the imported cattle were wiped out, as they had not evolved to endure drought conditions. (Kaufman and Franz, 1993, 361). In order to rebuild their herds, the African native breeds of cattle where reintroduced because they had evolved to withstand the effects of cyclic periods of drought. There are many things that people can do to help minimize the impacts of human interference. First, land can be set aside to give wildlife a permanent and secure place to live that is protected against poaching, harvesting of timbers and animals, and that is free
from the threat of human development. In order to make long term gains in conservation and wildlife protection, the public also needs to be re-educated on the importance of conservation and protecting the ecosystems of the world, and the importance of biodiversity to the quality of human life.
