The majority of meat and dairy produced in the US has been produced using artificial hormones. Some of the hormones used to produce meat and dairy are: Oestradiol, Progesterone,Testosterone, Zeranol, Trenbolone, and Melengestrol.
The European Union’s Scientific Committee on Veterinary Measures Relating to Public Health has determined that growth hormones in beef production poses a potential risk to human health.
Growth hormones are in meat and diary, but the hormones are also excreted in cattle manure and enters the environment, sometimes contaminating water and harming fish and other wildlife.
Since people don't need to eat meat or dairy and thus don't need to use hormones to produce meat and dairy, one can only conclude that meat people like hormones.
