The issue of what to do about growth hormones in cattle is complicated, and has not clear-cut solution. There are many factors involved with making a decision as to what to do about growth hormones.

First, there is the environment to consider. Grazing land for cattle, as well as fertilizers, affect the environment by allowing heavy metals to enter the soil and water. It seems that growth hormones, which allow for greater retention of protein in cattle, could possibly reduce the amount of land needed for grazing. This would have a positive influence on the environment, but possible negative influence on humans, as some believe that growth hormones are bad for public health.

Certain hormones are believed to be deleterious to human health. Links to cancer and thyroid cysts have been associated with certain FDA-approved hormones. However, no conclusive evidence suggests that these findings are accurate. As of yet, evidence is not strong, one way or the other, for the effects of growth hormones used in cattle production on human health.
Economically, growth hormones make sense. Naturally occurring hormones like testosterone or BGH are used to increase yield in beef and milk production, respectively. Considering hunger problems of the world, and the current economic slump of the United States, farmers and consumers need maximum cattle yield, as long as it is safe for the public. The use of growth hormones is highly regulated by the FDA; the practice of routine hormone injections has been approved by the FDA, and farmers would lose money if they veered from the FDA-approved dosage of hormones. This fact effectively cuts out a black-market for growth hormones amongst farmers.

The fact that certain hormones, like BGH, are banned in some areas of the world is an issue that needs to be resolved. Genetic modification is a part of the future, and global organizations need to begin setting standards for how to deal with new innovations in agriculture and cattle production. It makes no sense that some foods are deemed safe in one country, while deemed unsafe in another country. Some consensus must be reached by countries like the US, Canada, and European countries in the near future.
