hGH is an important part of fat metabolism, muscle development, and bone growth. Synthetic hGH can be used to treat children and adults suffering from hGH deficiency. More recently, competitive athletes have began taking hGH in an attempt to improve athletic performance. The use of hGH for athletics is banned by many major sporting organizations. A recent study of 44 athletes who took daily injections of hGH over 20 days showed that, on average, the athletes gained 4.2 lbs of muscle, but the gain in muscle did not translate to increased athletic performance.

Evaluate each statement regarding the use of hGH by competitive athletes to determine whether the statement is an example of an ethical, economical, societal, or environmental issue.

1. Athletes who play professional sports should be encouraged to take synthetic hormones to improve performance because their job is to win.
2. Athletes who took hGH did not improve their sport performance but did improve their appearance and marketability. This may lead to more opportunities for endorsements.
3. Drug companies producing synthetic forms of hGH for therapeutic purposes may be approached by sports teams or networks to supply hGH to their athletes or to create new versions of hGH that are not detected by current anti-doping technologies.
4. Athletes taking hGH may excrete excess hGH in their urine. These hormones may remain in water and affect the endocrine systems of other animals.
