This article talks about the effects of climate change, but more specifically about what it is doing to the production of meat in livestock animals. In this article, farmers talk about how the increase in heat causes pig production to decrease because they store less protein when it is hot because their sweat glands are inefficient. The overall physique of pigs are now thinner and lighter making the meat production decrease.

This article talks about the increase in pig population in a town in North Carolina and the effects the odors of the hogs and their feces have on human health. Steven Wing did research and found a correlation between air pollution from the pigs and an increase in rates of nausea, blood pressure, and respiratory issues in children and natives who live in this area. The stench of feces that causes air pollution is a natural thing, but not when the area is being overpopulated with these animals.

Feral pigs are domestic pigs that were released or escaped into the wild that now live as a wild animal. This article talks about how feral pigs are harming the environment. They wallow, root for food, and have selective feeding and destroy plants, crops, and habitats which disrupts biodiversity in areas that they live in.

Not only do an overpopulation of pigs and hogs cause air pollution, but also water pollution. This article talks about how in a town in Iowa there are large scale hog farms. In this town, the water has been contaminated because of all of the pig feces and manure. It explains how over 10 billion gallons of liquid pig manure in fields which causes runoff into the drinking water. There have been recent protests in these towns to stop the spread and large scale farming.

This article discusses two key points regarding cows. Cows themselves are not necessarily causing harm to the environment, and neither is the aspect of eating the meat produced by the cows. This article talks about how if we removed eating cows and the amount produced, only 2.6% of greenhouse emissions would decrease, so not significant enough.

This article discusses the effects of climate change on livestock. This article is specifically focusing on the effects climate change on cows. The key point made was that harvests and cow meat production was at an all time low this year since 1976 due to the droughts from the increasing climate.

As there are more demands for cattle, populations of cows tend to be larger now. This causes more methane gas to be released from the farts of the cows. The methane gas emissions have increased 10 times from 2000 to 2006, which contributes to climate change and greenhouse gases. Methane gas accounts for approximately 16% of greenhouse gases.

This article once again talks about the effect of cows' gases and the methane production, but more specifically about a study done to decrease this. Zhongtang Yu wanted to see if there was a way to reduce the methane, nitrogen, and phosphorus in their manure, which is a leading cause in the emission. He added additives to their diet to see if the cows would burp and fart less, and have a lower concentration of nitrogen, phosphorus, and methane in their feces.

All livestock contribute to greenhouse gases, large amounts of water consumption, and land use. This article makes the point that out of all livestock, cows contribute negatively the most out of all of these categories. A study was done that showed cows needed 28 times more land space and 11 times more irrigation than any other livestock.

Climate change is directly affecting the ocean and rising its temperature. This is causing the aquatic life to suffer due to the increasing temperatures. Fish populations have shrunk 35% in coastal regions near China and Japan. The fishing catches has declined 4%. Fish and aquatic life are suffering due to the rising temperatures from 1930 to 2010.

Overfishing is a rising problem in today's society. Not only is it affecting fish populations, but it eventually comes back to harm humans as well who are the cause of it. This article discusses how in the past, fishing used to be sustainable and regular, but now it is exploited. The focus of this article was to discuss how many humans rely on fish as their main food source, and how if we continue to overfish them instead of just a constant regular fishing, then the population will eventually be scarce and cause harm to those humans that are dependent on the fish as well.

Main pollution topics in the ocean such as straws and plastic bags have been widely covered by the media and publicized, but there are still many aquatic problems not brought up to people's attentions. This article discusses one of the main causes of fish death most people did not even know about. Mark Browne did a study and found microscopic pieces of plastic in fish's blood cells. These particles cause harm to the organs and release chemicals in the fish's bodies which can cause lethal effects.

As discussed in previous articles, increasing climate causes more fish deaths due to the higher ocean temperatures. This article talks about more affects climate change has on fish, besides the deadly outcomes. Higher temperatures cause fish's metabolism to drastically increase, which means fish overall are now shrinking in size. This negatively affects their survival, development, and humans who rely on their dietary needs of fish.

Runoff from chemicals is a modern day problem with all of the new advances and chemicals made. This article talks about how some chemicals are spreading into the ocean and infecting the fish populations living there. Not only does this harm the fish's health, but makes them toxic to humans who want to consume them. The fish end up with parasites and deadly diseases growing inside of them.

Poultry is one of the fastest growing meat consumption areas in the world. With more and more chickens being killed for their meat as opposed to an average amount, there have been some strange consequences. This article talks about how the populations of chickens killed is higher than any other bird population. This article explains how many birds have beginning to be silent and not sing as a result of being in pain or struggling to remain above extinction. This affects humans because they are a main source of protein, but cannot be over killed.

With all of the negatives that come from cows and producing beef, many people have just switched to eating chicken and poultry. This article explains why this is a problem that cannot happen. Not only would this cause an over population of chickens and an over killing of them, but chickens also require a lot of land and irrigation. Cows do use a lot more of these resources, but it is more difficult to account to the needs of chickens because to equal the amount of beef to poultry, requires a lot more chickens. Chickens must be kept indoors to be slaughtered, so there would be more land taken up because of the over population of chickens.

Chickens excrete some elements that contribute to pollution. This article talks about how it raised right and given proper nutrients this will not occur as much. When given a well balanced diet, chickens will secrete less phosphorus and nitrogen into the environment, which are two main chemicals found from livestock pollution.

When massive amounts of chicken are bred, growers are left with litter, mixture of manure and bedding. They typically dispose of this litter by spreading it over fields. When it rains, this goes into nearby water as runoff, contaminating it and causing harm to the nearby environment. Humans and their water-quality are affected as well.

This article focuses on the effects of farming a lot of chicken in small confined areas. It talks about how this causes a contamination of soil and pollutes air and water. As previously discussed, this can harm human health, but it can also harm other animals. With runoff from all of these highly populated areas of chicken, fish and local aquatic life will suffer from the chemicals and feces/manure that will buildup and contaminate where they live.

Many animals that humans cherish, whether it be for the consumption of them or for their looks, all have an impact on the environment whether we know it or not. For my CCA topics, I chose to focus on four different animals that are common to society and see what effects they have on the environment and local ecosystems today. The reason why I decided to focus on these topics is because most animals seem harmless, but as the population of humans is increasing, I want to see what effect all of the species have on the environment and humans as well. To focus in on one specific topic, I am going to discuss the research I did on pigs and hogs in today’s culture. Pigs were my initial topic before I decided to expand it to other animals. I started with pigs because they are my favorite animals and I have also wanted one as a pet, especially on my farm. Having this background, I wanted to see what effects pigs have as a whole especially if humans are producing more and more of them. I looked into how the environment is affecting pigs and also how pigs are affecting the environment.

Climate change and the increasing global temperatures is a rising problem in today’s society. Not only is it affecting humans, but it is also affecting animals and different species. One of the articles I read and discussed talked about how the increasing climate is causing pig production and livestock meat production to decrease. When the temperature increases, pigs’ sweat glands are inefficient causing them to store less protein. This overall causes the pigs’ physique to be thinner and lighter, so there is less meat to be used for production. This causes issues for the pigs because their overall health is decreasing. This also causes problems for humans who are dependent on the meat production of pigs because if they are smaller, there is less meat to be produced and sold for human consumption.

One problem pigs cause for the environment is their production of manure and feces. Some of the articles I read talked about how pig and hog manure causes problems for human health and also water contamination. With the population of humans increasing, more pigs are needed to keep up with the needs of humans. This causes small areas to be highly populated with pigs to be able to use them for meat production. With highly populated areas of pigs causes there to be excessive amounts of manure in small areas. This stench builds up and is found to have a correlation to air pollution and human health risks such as nausea, increase in blood pressure, and respiratory issues. This is only a problem because the areas are so densely populated, so there is a large concentration of manure being produced causing this unbearable and harmful stench. With an excessive amounts of manure buildup, this also runs off into local areas of water. This contaminates drinking water for humans and other animals.

Pigs are animals that are often overlooked in today’s society. After reading articles, I learned that pigs are affected by the environment in many different ways and also impact the environment whether it be negative or positive as well.
