Hormones in our foooooood

Canada is one of the largest agricultural producers and exporters in the world. The rapid global human population is increasing at an incredible rate that the consumer demand is changing agriculture. Many provinces and states are increasing the amount of agricultural land dedicated to growing crops so they can have a higher amount of buisnesses making and selling organic products. Although this is a more greener and healthier way to react to the demand, there is also another way to increase consumer goods! What is that you may ask? Well, think about a chicken that can grow twice as fat and lay twice as many eggs. That would be every farmers dream! Well, it has become a dream come true because they have resulted in injecting hormones to increase the rate of animal growth.
Hormones are chemicals that are produced naturally in the bodies of all animals, including us humans! Their job is to release chemical messages into the blood by hormoneproducing organs taht travel to and affect different parts of the body. These hormones are very important because they control major body functions such as growth, development, and reproduction. But...... the hormones that are being injected to animals are hormones that can make young animals gain weight faster. They help reduce the waiting time and the amout of food eaten by an animal. In dairy cows, hormones can be used to increase milk production. This means that hormones have total control of the profitability of the meat and dairy industries.
As early as the 1930s, humans realized that cows injected with material drawn from bovine pituitary glands would produce more milk. This is when hormones was first introduced to animals.
There are six different kinds of steroid hormones that are currently approved by FDA for use in food production in the US which are estradiol, progesterone, testosterone, zeranol, trenbolone acetate, and melengestrol acetate. Estradiol and progesterone are natural female sex hormones while testosterone is the natural male sex hormone. The other three hormones are synthetic growth promoters which are hormone-like chemicals that can make animals grow faster. As of right now, federal regulations allow these hormones to be used on growing cattle and sheep, but not on poultry or pigs.
Steroid hormones are usually released into the animal from a pellet (ear implant) that is put under the skin of the ear. The ears of the animals are usually thrown away at slaughter but improper use of pellet implants in other parts of the animal can result in higher levels of hormone residues to remain in the edible meat. Federal regulations prohibit their use in this manner. Melengestrol acetate is also available in a form that can be added to animal food. When natural hormones are fed to the cattle, the level of their hormones increases from 7 to 20 times more.
After thorough research, the Veterinaryu Meeasures Relating to Public Health (SCVPH) came to the conclusiont hat "no acceptable daily intake could be established for any of these hormones" and those who eat food products having these hormonal residues are at a great risk of severe hormonal imbalance as well as various types of cancer.
If there are numerous of risks that are concerned with hormones being injected in our food, why is it even a question if humans should eat this? In conclusion, I think that the increase in human population has grown so quickly that the agricultural industry has relied more and more on injecting their animals with steroids to keep up with demands.
