Animal Cell Model

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 Local breeds of African cattle had almost completely been replaced by these imports, however, a few small herds remained.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.

The availability of clean drinking water for animals from a formerly reliable source is eliminated by pollution, as is the aquatic wildlife that once served as an important link on the food chain for land animals. The once natural balance in population and general health of all wildlife is altered beyond repair, as one species nearly becomes extinct while another grows in numbers that cannot be supported in the long-term by available natural resources. Lastly, water pollution not only affects the wildlife at the location of the pollutants presence but with the earth's natural heating and cooling the pollution is spread to distant locations globally through acid rain. Unfortunately, the affects of water pollution on wildlife that is delivered so discretely and without obvious notice often results in damage to existing ecosystems that may not be assessed for decades. Atlanta isn't the only attraction in Georgia. Acres of untouched land reach out inviting avid hunters into their living forests.
