By creating herds of cloned animals that have the same genetic composition, either entirely or with respect to some particular traits, the diversity of those animals is significantly reduced. As a consequence, cloned animals and herds may be more susceptible to disease and less able to withstand an outbreak. This could have serious repercussions for the population as a whole and for the agriculture industry.

The range of potential environmental impacts associated with the proliferation of cloned animals has not been thoroughly investigated and is largely unknown and uncertain.[1]
