Feedlots

Peer-Review #1: Prevalence, Antibiotic Susceptibility, and Diversity of Escherichia coli O157:H7 Isolates from a Longitudinal Study of Beef Cattle Feedlots –
Escherichia coli O157:H7 (E.Coli) has been identified to be in one of the four feedlots. A recent study shows that there is a way to cure E.Coli infections that is founded in the animals in which we consume daily. Researchers say that the cattle that live on the feedlot did not have the E.Coli infection that it was brought in from the cattle that had not been injected with antibiotics or hormones yet. Therefore the cattle’s feces released CO2 into the air causing the feedlot cows to take in the CO2 giving them this infection of E.Coli.

Do to the fecal matter that the cows produce researchers have found Salmonella. They took samples of the fecal matter and was determined that due to Salmonella, the humans eating the cattle were getting sick due to that. Once the feces is released from the cattle CO2 is produced calling air pollutant which can get us sick but not only is the air pollutant a problem with this issue is how the animals are getting fed as well as how the feedlot owners are injecting into the cattle such as the hormones and antibiotics to get the fatter and to produce meat then the average cow who is not getting injected with needles everyday. Since we eat the cattle it is for sure determined that we will consume some of the hormones injected into them causing us to get sick and possibly even death may occur sue to the percentage of Salmonella or E.Coli the cattle may have.

Enviromental Science Blog #5: Meat Industry and Climate Change

Deforestation, Global warming, and wasted land, water and air pollution are all directly linked to eating meat. These environmental issues are a serious problem of our time. “According to Environmental Defense, if every American skipped one meal of chicken per week and substituted vegetarian foods instead, the carbon dioxide savings would be the same as taking more than a half-million cars off U.S. roads.” Knowing this gives me the knowledge to make a difference within this world and to be a leader to others, to show them that this planet Earth we live on is more important then we think.
America itself has very limited resources some that are even wasted such as land, food, energy, and water. Without these resources animals that we eat are not getting enough water and food which then doesn’t give them energy – and the animals get there energy from the sun; it is a cycle of photosynthesis but due to global warming animals aren’t consuming as much therefore, antibiotics are injected into the animals which causes the animals to get fatter. Not only is global warming an issue that is affecting the meat industry but so much more is as well - such as, feces, the water and the air.

This Article talks about how the climate is affecting the animals. It tells us what we need to do, how it can be done, and what else is wrong with this issue which helped me a lot and made me think even more.

2.principles, enforce RSPO, and &. "Take a Bite out of Climate Change » Food Industry News & Trends." Take a Bite out of Climate Change. N.p., n.d. Web. 11 Feb. 2010. .
This article mainly talks about what we can do to stop global warming from affecting the meat industry. Although it talked about climate change and how it affects the meat I don’t think it was much help.

I loved this article it made me think about certain situation so much. “Shouldn’t we focus on forcing the meat industry to pay up for its massive externalities, including its contribution to climate change?”
