IFAP topic 1: public health

IFAP systems are very harmful to workers, people who live nearby, also those who live far away from the systems. They are harmful because they produce a lot of air pollution and water pollution. Workers and people who live nearby the IFAP systems go through more problems that affect their ability to breathe clean air. People who work in the IFAP systems can bring nasty diseases into their homes, which causes the disease to spread and eventually can affect a whole community population. This disease that the meat carries causes the human body to form a resistance against it. Then when there’s a time where you need assistance with something minor, the antibiotics most likely won’t work because your body has created a resistance to it because you’ve been around the meat with the disease. In the end appropriate treatment of great amounts of waste needs to occur or it will result in contamination in close waters. This will cause the water to have very harmful levels of toxins, such as viruses and nasty bacteria.

EROI Hw

Which energy source should we extract and use first, oil shale or tar sands? Why?

•  We should extract oil from tar sands first. We should do this because they have a higher EROEI than oil shale does.

Describe one similarity between the process used to get oil from tar sands and the process used to get oil from oil shale.

• Both tar sands and oil shale must be heated in order to obtain the oil from it.

Describe one key difference between the process used to get oil from tar sands and the process used to get oil from oil shale.

•  A key difference between the process used to get oil from shale and tar sands is when they collect it. Tar sands are mined while oil shale is drilled. Drilling is less intruding than mining is. Rock containing oil shale has to be heated to take the oil. Tar sands is extracted then heated in water, which is less energy consuming than heating oil shale.

Explain, in terms of EROI, why the author believes "off-shore oil drilling may be a smart way to actually reduce greenhouse gas emissions in the long run".

• When it comes to off-shore drilling there is a higher EROI and consequently you get more oil and also have to use less fossil fuels to acquire.  In the long run, this means we produce more oil without having to use as much oil or fossil fuels to get it. This causes lower rates of CO2 pollution in the air.

Use EROI/Best First Principle to explain one decision that you have made in your day-to-day life. This could literally be anything, but I am looking for new examples other than the energy resources we have been studying. In other words, you should provide an example of how EROI influenced a decision at your individual level rather than the societal level.

• When tests come up I don't study the night before. So the day of the test I have a lot more energy to actually take the test because I wont be tired from studying.
