Polluting Pigs Hit Again Over Air Emissions in Iowa
Imagine settling into an idyllic country locale only to have a polluting pig CAFO move in next door. Living near a CAFO can be like being held prisoner in your home, unable to go outside because the air has been tainted. In one of the latest cases, Iowa residents are suing the Iowa Department of Natural Resources over noxious air emissions being released by local CAFOs. In December 2017, four residents of northeast Iowa petitioned the state’s DNR, asking them to regulate emissions from CAFOs. While Iowa code requires CAFOs to retain its manure prior to disposal, the petition noted that the CAFOs are venting manure-laden air into the surrounding environment 24/7:1.
The petition cited research by Jillian Fry of Johns Hopkins University, which noted the health and environmental risks posed by CAFOs and the inability of state agencies to address the related public health concerns. The next step for the residents was to file a lawsuit asking for regulation of the emissions, in particular because the area is now home to CAFOs raising some 25,000 pigs all within 5 miles of an elementary school. If left as is, the resulting fumes would kill the animals, so the CAFOs use fans to blow the toxic air out of the building – and into the surrounding communities. While Iowa regulates CAFO manure in liquid form, this doesn’t cover the manure particles found in CAFO air emissions, which aren’t regulated. For children, living near the state’s many CAFOs can pose serious health consequences.
She’s right to be concerned, as a number of studies have looked into the effects of CAFO air emissions on schools and children’s health, with disturbing findings. The simplest solution to the complex problems created by CAFOs is to turn away from the CAFO model entirely and toward the much more sustainable, humane and healthier grass fed model.
How to Care for Your Guinea Pig: Getting to Know Your Pet
If you are one of them but are not sure about how to care for your guinea pig, read on to learn about where they come from, their personalities, care, health issues, and socialization. The origins of guinea pigs are in South America, and though there are many species of this animal, only the domestic cavy can be kept at home as a pet. Their average lifespan of a guinea pig is approximately four to eight years, so if you are planning to adopt one, know that you are making a long-term commitment. You can keep your guinea pig indoors or out, but make sure their environment is quiet. If you do keep your guinea pig outside, get her a large wooden hutch, with a separate section for sleeping, eating, and play.
Avoid giving your guinea pig potatoes or tomato leaves because these can be quite poisonous for a guinea pig. Finally, make sure to give your guinea pig lots of clean and fresh water, in large quantities, every day. A guinea pig infected with urine problems may be prescribed antibiotics, but in some cases, they may require supportive care, therapy, or even surgery. Encourage adequate exercise by allowing your guinea pig to run about the house as much as possible. At first, it may seem that your guinea pig is not truly connecting with you, but after a while, you will notice that they are very happy and friendly creatures once they recognize you and are given proper love and care.
Having more than one guinea pig is a good idea; otherwise; they might end up being lonely. We have laid out to you some facts about guinea pigs and a few quick points on how to take care your guinea pig.
Students will be provided a copy of the simulation program to work at their own pace for this assignment. The aim of this assignment activity is to provide an opportunity for you to design and perform experiments to investigate the properties of agonist and antagonist drugs using the isolated ileum of the guinea pig, and investigate the pharmacological effect and mechanism of action of given antagonist drugs on the contractility of isolated guinea pig ileum. Experimental Setup: The software simulates an experimental setup on an isolated piece of guinea pig ileum removed from a freshly killed guinea pig and suspended in warmed and aerated physiological solution called Tyrode’s solution. The tissue is carefully suspended in an organ bath with the bottom end of the tissue fixed and the top end attached to a freely moving isotonic lever which is in turn connected to a transducer. The lever responds to the contractions of the longitudinal muscle in the ileum and the resulting movement is converted into an electrical signal by the transducer.
The electrical signals are then sent to a chart recorder which displays the signals as a trace. The organ bath is kept at a constant temperature of 37C by means of a water jacket which circulates water at the required temperature. A variety of drugs are added into the organ bath to observe the effect on.2 intestinal contractility. The set up also allows examining how antagonists can interfere with agonists at tissue level. Experimental Procedure: When performing experiments in which you are.
