Pollution https://www.sciencedaily.com/terms/pollution.htm

Pollution comes from environmental contaminants often causes by humans. Some examples of pollution can include: air, water, and ground pollution. Pollution can cause disease, including cancer, lupus, immune diseases, allergies, and asthma. Pollution can often be the cause of death for many animals in wildlife as well. It's causing out Earth to suffer and the organisms on it as well. One of the main causes of air pollution in the world is the emissions from cars.

This article basically explained the definition of GMO's which are a genetically modified organism. Some of the new material I learned is that genetically modified crops are made to be herbicide tolerant which has made it weed resistant. As a result sometimes as much as four time more herbicide has to be sprayed. What I found the most interesting that in 2015 glyphosate, an ingredient used in Round Up or herbicide, is a probable human carcinogen. This article was written by a holistic nutritionist with more than 20 years clinical nutrition experience.

LA TIMES Article: Polluted air, health problems brought by Southern California fires are expected to linger

Article Link: http://www.latimes.com/local/lanow/la-me-fire-air-20171209-story.html

Module 12 discussed the impacts of poor air quality on human healthy. Recently, my sister, her boyfriend and my nephew were affected by the Thomas Fire in upper Ojai, CA. Their entire property had burned to the ground, but thankfully, they made it out alive as the flames were very close to them leaving them only a short time to quickly evacuate. Now, another risk imposes them as bad air pollution enters their lungs. This article discusses the current severity of polluted air in southern California contributed by the ongoing wildfires. The article mentions, “The air is not healthy for you because of the fire. There’s chemicals and all sorts of toxins that got released into the air.” The air quality has been so bad that people have been advised to wear N95 and P100 respirators to protect against particulate matter.

Article Review on Gecko Evolution

http://onlinelibrary.wiley.com/doi/10.1111/j.1469-7998.1954.tb07789.x/abstract

I read an article out of the Journal of Zoology (Volume 124, Issue 3) by Garth Underwood which discussed the 'classification and evolution of geckos'. The article was easy to understand and detailed over thirty different topics about the diferences in the evolution due to locality differences. For example, Garth Underwood discussed how few geckos have eyelids and how this evolution had come to be. Overall, I found this article to be very descriptive, informative, and helpful in furthering my own knowledge about gecko evolution.

Ethical Concerns with fracking.

I read an article from the University of Pittsburg that dealt with some of ethical issues surrounding hydraulic fracturing for our critical thinking project. I thought overall, it posed some really good points and made me think about natural gas in a different way. l think for a lot of people where we get our energy is not something we think about, as long as we get it. So we also don't think about the people behind the energy. The article made me think about the type of men and women risking their lives in order to keep our society moving. It is a high pressure job and something that requires many different kinds of training. They not only have to knowledgable in chemical engineering. These workers need to be trained on how to deal and report issues that may have fatal consequences. Along with raising ethical concerns, I thought the article did a good job explaining what fracking is, some of the other issues associated with it, and some possible solutions. Although this was helpful, it did make the topic of the article a bit unclear. The title states that it will discuss an ethical perspective, but I did not not think the majority of the article was spent on this.

Today, transportation is the because contributor towards air pollution. It contributes primary and secondary pollutants to our atomosphere.

https://www.ucsusa.org/clean-vehicles/vehicles-air-pollution-and-human-health/cars-trucks-air-pollution#.Wi33QUqnE2w ;

Cars, Trucks, and Air PollutionTransportation is the largest single source of air pollution in the United States.

Dirty cars, dirty air

In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.This air pollution carries significant risks for human health and the environment. Through clean vehicle and fuel technologies, we can significantly reduce air pollution from our cars and trucks, while cutting projected U.S. oil use in half within the next 20 years.

The ingredients of air pollution

Cars and trucks produce air pollution throughout their life, including pollution emitted during vehicle operation, refueling, manufacturing, and disposal. Additional emissions are associated with the refining and distribution of vehicle fuel.Air pollution from cars and trucks is split into primary and secondary pollution. Primary pollution is emitted directly into the atmosphere; secondary pollution results from chemical reactions between pollutants in the atmosphere. The following are the major pollutants from motor vehicles:

Particulate matter (PM). These particles of soot and metals give smog its murky color. Fine particles — less than one-tenth the diameter of a human hair — pose the most serious threat to human health, as they can penetrate deep into lungs. PM is a direct (primary) pollution and a secondary pollution from hydrocarbons, nitrogen oxides, and sulfer dioxides. Diesel exhaust is a major contributor to PM pollution.
Hydrocarbons (HC). These pollutants react with nitrogen oxides in the presence of sunlight to form ground level ozone, a primary ingredient in smog. Though beneficial in the upper atmosphere, at the ground level this gas irritates the respiratory system, causing coughing, choking, and reduced lung capacity.
Nitrogen oxides (NOx). These pollutants cause lung irritation and weaken the body's defenses against respiratory infections such as pneumonia and influenza. In addition, they assist in the formation of ground level ozone and particulate matter.
Carbon monoxide (CO). This odorless, colorless, and poisonous gas is formed by the combustion of fossil fuels such as gasoline and is emitted primarily from cars and trucks. When inhaled, CO blocks oxygen from the brain, heart, and other vital organs. Fetuses, newborn children, and people with chronic illnesses are especially susceptible to the effects of CO.
Sulfur dioxide (SO2). Power plants and motor vehicles create this pollutant by burning sulfur-containing fuels, especially diesel. Sulfur dioxide can react in the atmosphere to form fine particles and poses the largest health risk to young children and asthmatics.
Hazardous air pollutants (toxics). These chemical compounds have been linked to birth defects, cancer, and other serious illnesses. The Environmental Protection Agency estimates that the air toxics emitted from cars and trucks — which include Benzene, acetaldehyde, and 1,3-butadiene — account for half of all cancers caused by air pollution.
Greenhouse gases. Motor vehicles also emit pollutants, such as carbon dioxide, that contribute to global climate change. In fact, cars and trucks account for over one-fifth of the United States' total global warming pollution; transportation, which includes freight, trains, and airplanes, accounts for around thirty percent of all heat-trapping gas emissions.

Article discussing air pollution. https://www.theguardian.com/cities/2017/feb/14/bakersfield-california-bad-air-pollution-us

This article discussed the reasons why Bakersfield has one of the worst air qualities amongst the U.S. Throughout the article the author brings up some compelling reasons as to why the air quality in the Central Valley is really bad. For example, the surrounding agriculture, industrial power plants and even the traffic from cars release emissions into the air making it harder for its residents to breath.The article states statistical data correlating with specific health issues that people suffer from in Bakersfield. The air quality with causes such as asthma, cardiovascular diseases and chronic obstructive pulmonary diseases. However, the town has paved new regulations and standards to reduce the amount of harmful emissions into the air. Working on a common goal to achieve better air quality can be accomplished if everyone follows these regulations and continues to limit certain things in their daily lives.

Article on Climate Change http://science.sciencemag.org/content/306/5702/1686.full

In this article it suggests that the majority of observed warming in the past 50 years has been due to greenhouse gases and human activities are mostly to blame for this. Because of humans temperature's are rising and ocean temperatures are too. There has been debates whether humans are the cause of this or is it just mother nature. Many studies have been done but scientists have not been able to come to a conclusion.

Article Review- Should Fracking Stop?

I read an article arguing two sides of a debate on fracking. One side was against fracking, saying it is too high risk, while the other side of the article was saying it was too valuable of a resource to stop. The risks of fracking include harmful effects on the environment. When extracting the natural gas, harmful elements can contaminate nearby water resources as well. However, the other side argues that fracking is crucial to our economy and those benefits outweigh the environmental risks. This debate is further discussed in the article.

The Impact of the Fracking Boom on Arab Oil Producers

This article presents information in regards to four major contributions. First, it presents information in regards to the investigation to the extent to which the U.S. fracking boom has affected Arab oil exports to decrease since late 2008. Second, the article presents the information in regards to calculating for the first time by how much the U.S. fracking boom has lowered the global price of oil. Using an specific type of methodology called "novel econometric methodology", it is shown that in mid-2014, for example, the Brent price of crude oil was lower by $10 than it would have been in the absence of the fracking boom. Thirdly, the article provides evidence that the decline in Saudi net foreign assets between mid-2014 and August 2015 would have been reduced by 27% in the absence of the fracking boom. Finally, the article concludes with the policy choices faced by Saudi Arabia and other Arab oil producers.

Renewable Energy

I read an article on science daily that talked about creating wind farms in the ocean. The thought is, that since there is a lot more wind out over the ocean since nothing is blocking it, that we can create more renewable energy. They are not sure if it will work, because there may be a capacity to how much energy can be created.
