Global Perspective

For my final blog post of the term, I will focus on Global Perspective. A global perspective is a viewpoint that attempts to understand the place of individuals, groups, cultures, and societies in the world and how they relate to each other. An example of a global perspective is studying the implications of economic policies on illegal drug use specifically the supply chain, where the drug is produced, and the local area where the drug is sold.
The link below provides information on the global perspective of climate change. In terms of the math part of this, According to The Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change, the atmospheric concentration of CO2 has increased from 280 ppm in the period 1000–1750 AD to 379 ppm in the year 2005. The concentration of methane in the atmosphere has more than doubled from 700 ppb in the period 1000–1750 AD, to reach a concentration of 1774 ppb in the year 2005. The concentrations of hydrofluorocarbons, perfluorocarbons, SF6, and N2O have also increased. The tropospheric concentration of ozone has increased even though its stratospheric concentration has decreased.

Gallons of Water Wasted Per Day

Posted on by

For this week’s bog topic, I thought it’d be interesting to reach out to my friends and see how many gallons of water that they believe that they waste a day. Water waste is a huge issue when it comes to sustainability across the globe. Water can be wasted in many different ways and I feel that is often over looked. For example, keeping the water running when you brush your teeth, taking too long of showers, pouring out drinking water, etc. After reaching out to 10 of my friends, I put the data into a bar graph, which is pasted below;

The range of answers is quite obvious as one of my friend’s stated that she doesn’t waste any water, meanwhile, another one of my friend’s claimed that she wastes 20 gallons of water a day. By asking my friends this question, it was intended to make them think of all of the ways that they waste water and in return think of the ways that they can reduce water waste. Making these small changes can have a big impact on our globe.

U.S. Health Care Affordability in 2020

This article looks at health insurance coverage for adults in America during the first half of 2020. This article presents results from the Commonwealth Fund’s latest Biennial Health Insurance Survey, which assesses the extent and quality of coverage for U.S. working-age adults. The survey began in 2001 and has three measures to gauge the adequacy of insurance coverage. The first is whether or not people have insurance. The second is if they have insurance and whether they experienced a gap in coverage in the prior year. The third is whether high out-of-pocket costs and deductibles are causing them to be underinsured, despite having continuous coverage throughout the year.

The survey for this article began in January of 2020. A nationally representative sample of 4,272 adults ages 19 to 64 was interviewed about their health insurance coverage through June 5.

The article gives important highlights of the survey, explains who is underinsured, and gives a graph that shows the percentage change of people that are underinsured over ten years.

The article goes on to present many graphs that present the percentage of ethnic groups who are uninsured, the change over time of adults in employer plans that are underinsured, change over time of the percentage of adults with a share of private insurance with deductibles of $1,000 or more, the percentage of people with inadequate insurance coverage that have more problems paying medical bills, the percentage of medical debt that leaves people with lingering financial problems, the percentage of uninsured or underinsured adults who often avoid or delay getting needed health care and medications, the percentage of people with higher deductibles who report financial problems more frequently because of medical bills or delaying care because of cost, then finally the percentage of adults who look for but do not buy plans in the individual market or marketplaces cite because of affordability.

The article concludes by explaining how the study was conducted.

This article and information relate to Social Injustice by showing the high uninsured rates of ethnic groups. The uninsured rates of black and Latino people are much higher than the uninsured rate of white people.

Food Security and Sustainable Agriculture

Posted on by

As the population of the world continues to grow, this increases the demand for food. For every person that is born, it’s another mouth to feed and eventually another family to feed. Also, it’s important that the food being served to the public is safe to eat and good for health.

The main goals of food security and sustainable agriculture are to improve the global supply chain, decrease food losses and waste, and ensure that all who are suffering from hunger and malnutrition have access to nutritious food.

In 2012 world leaders met at the Conference on Sustainable Development and agreed that everyone has the right to have access to safe nutritious food, adequate food, and to be free from hunger. At the conference, the UN Secretary-General created and launched a Zero Hunger Challenge which called on governments, civil society, faith communities, the private sector, and research institutions to work together to end hunger and eliminate the worst forms of malnutrition.

The goals of the Zero Hunger Challenge are: to make sure there are zero stunted children under the age of two, 100% of people have access to adequate food all year round, make sure that all food systems are sustainable, there is a 100% increase in smallholder productivity and income, and that there is zero loss or waste of food.

These are big goals that can be accomplished over time. Some important math that is important for accomplishing these goals is the use of the rate of change. This is important to calculate how fast the population of the world is increasing or decreasing. To calculate the rate of change two important pieces of information is needed. The first is the amount of change that occurred and how long in terms of the time it took for that change to happen. The formula is the average amount of change divided by the amount of time required for the change to happen. This is a good way to calculate how much the population of the earth changed in one day, week, month, or year. Once these numbers are determined they will give a good idea of how much food needs to be produced and distributed.

Climate change and human health

Posted on by

While we often think about the environmental effects of climate change, we don’t always consider how those environmental changes can affect human health.  Global warming is one of the most prevalent issues associated with climate change and while many people have noticed the effects of this issue, not many know the health issues that come from this increased global temperature. According to the EPA, unusually hot summers with high temperatures and heat waves have become more and more common over the years.  With this increase in hot weather comes an increase in heat related deaths. For instance, the rate of heat related deaths in the United States has increased from 1979-2018.  In 1979, the rate of deaths was 0.240 per million people.  In 2018, that increased to 1.635 per million people, making the total change 1.395 per million people and making the percent change between 1979 and 2018 a 581.25% increase.  With a growth factor of 6.81, you can see the large increase in deaths caused by heat in the last 40 years alone.  Climate change, especially global warming, can have an extreme adverse effect on human health, which we are already starting to see.  If we don’t do something to keep the global temperatures from becoming even more extreme, we can expect to see the rise in heat related deaths become even higher.

Water is Life

Posted on by

Water is an essential part of the human experience. We are made of water. We use water to drink. We use water to clean. We use water to cook. We use water to bathe. In fact, the origins of life on earth stem from the water itself. Water is essential for life on earth, however, it is being jeopardized by the huge amounts of pollution that humans are creating. Companies and industries are particularly bad for producing waste that ends up in our water. This is a serious threat to human health. Unbelievably “Unsafe water kills more people each year than war and all other forms of violence combined” (Denchak). While citizens of developed countries may not think twice about the water that they drink, and how they get it, citizens of developing countries are still at risk of being poisoned by unhealthy water. Many people believe that water is a basic human right. In my opinion, the fact that Americans use 5 times more than the global average is pretty sad. Access to water is a human rights issue as well. Another huge problem is that the vast majority of water on earth is not drinkable. Most of the water on earth is saltwater that cannot be used as a drinking source for humans and  “Less than 1 percent of the earth’s fresh water is actually accessible to us”. This means that the amount of freshwater that we have as a resource for the almost 8 billion people here on earth is very limited. While the human population continues to grow, eventually it will get to the point where there simply is not enough water for everyone on earth. This is a very depressing thought to me. I believe that developed counties have a responsibility to help provide developing countries with access to water. If the United States wants to be a great country, it must act like one.

Rising Co2 levels impact on human health

Posted on by

When researching rising levels of CO2, it’s easy to find topics such as climate change and how that may affect the environment as we know it.  However, what’s not talked about throughout the media often is the affect the rise of Carbon dioxide has on human health.  In fact,  CO2 levels of 1,000ppm have been found common in small confined spaces, such as classrooms, offices, bedrooms, and planes.  Now this may not seem that important, but carbon dioxide levels over 1,000ppm can cause inflammation as well as reduced cognitive function, and those levels are not that hard to pass within the confined spaces that I mentioned.  Chronic Exposure  levels from 2,000ppm to 3,oooppm can cause even worse damage such as kidney calcification and bone demineralization.  When thinking about the environment, and how climate change is impacting the world, that also causes quite the dilemma when it comes to human health as well.  Air pollution kills 9 million people every year, and as the temperature rises, the problem only gets worse.  In a 2008 study, rising levels of CO2 can cause the temperature to go up by 1 degree celsius, causing ozone damage which can kill 22,000 people due to asthma or some sort of respiratory illness.

I think human health is very important to note since there are still quite a lot of people who do not believe in climate change still to this day.  Possibly bringing up the fact that CO2 levels rising can directly affect one’s health may shine a light on the subject, since the affect on the environment may not be enough.  It’s very evident to see that within the media there’s been a rise in hurricanes and fires, and ticks have been increasingly apparent due to climate change.  Although these are little things at the moment, it’s only a matter of years before there’s irreversible damage to the planet as well as people’s lives.  Hopefully with more outlets supporting the negative impact climate change has on human health, more people can be aware and acknowledge the dangers.

Fossil Fuels and Human Health

Posted on by

We talk a lot about fossil fuels, greenhouse gases, and how the impacts they have on the environment. Something that is not often talked about, however, is the impact of fossil fuels on human health. According to an article published by the NYU School of Law, the burning of fossil fuels and the inhalation of the subsequently polluted air contribute to several health conditions, including, but not limited to: asthma, cardiovascular disease, and preterm birth. What’s more, the article states that “if fossil fuels were completely eliminated, the global average life expectancy would increase by 1.1 years”. The article then goes on to describe the effects of burning fossil fuels, and different variations of pollutants. The thing that interested me most about this article was the mention of a study done in Southern California, where diminished levels of particulate matter (mixture of solid particles and liquid droplets) and nitrogen dioxide over a 21 year period lead to 20% fewer cases of childhood diagnoses of asthma. This is just one of many examples of how fossil fuels and greenhouse gases effect both the environment, the world around us, and humanity as a species.
