Have you ever seen an ad, picture, or clip on the news of a developing country and wondered, “What’s it like to live like that?” Your answer might be based on actual experience if you lived in that country, or you might form your opinion by reading about conditions in different types of countries or watching a video, such as any of these:

The United Nations and World Bank compare such parameters as gross domestic product (GDP), education, literacy rate, health care, and life expectancy to distinguish between developed and developing countries. Using these measures and those for standards of living, level of industrialization, and quality and range of infrastructure, countries are placed in a sort of scale called the Demographic Transition Model (DTM).

(Roser and Ortiz-Supina, 2018)

Assignment Details

Choose ONE of the following four topics. For that topic, and using what you have learned about living conditions and the DTM, discuss your experience in a Phase 4 country (presumably the United States) and compare and contrast that with the same resource in a country in Phase 2 or 3 of the DTM.

Topic Choices

  • Describe your educational experience in a developed country, and compare it to the educational experience in a developing country. 
  • Describe the last time you went to the hospital, and contrast how this experience might differ in a developing country.
  • Describe your last trip to the grocery store, and compare the availability of food with that in a developing country. 
  • Explain your biggest use of water, and then describe how this differs from the availability and supply of water in a developing country.

Earth’s Greatest Enemies?

Climatologist James Lovelock (http://www.jameslovelock.org/) (originator of the Gaia_hypothesis ) once said that Earth’s greatest enemies were the Three C’s: cars, cows and chainsaws because of their contributions to destabilizing planetary climate.

A. In this final Discussion Forum, you will answer the following question to show your ability to find connections among the environmental issues that you have learned about in this course.
Number your responses so I can see you have addressed each part.

You must cite specific evidence from any Unit of the course to support each of your responses.
Each contributing factor is worth 4 points x 3 = 12 points.

1. What and how do each of these things contribute to the destabilizing of Earth’s atmosphere and its climate?

1a. cows?
1b. cars?
1c. chainsaws?

You must cite at least one source in your posting. Please use MLA or APA formating to cite your source. 

Reminders:

  • Loss of land plants because of human activities will not result in a reduction of atmospheric oxygen because most of planetary photosynthesis and its resulting oxygen production is in the oceans.
  • Be sure to back up your explanations with some research before discussing this topic online with your classmates. Be sure to read relevant sections of your text (and supplementary readings from this Module) and look online.  Start with the links in this question and the Resources listed for this Module.

Power’s on, Power’s Off!

How convenient is it to have electricity come right to your home? We use electricity for so many things: lighting, heating, cooling, entertainment, cleaning, food storage and preparation, and even for taking this class!

Generating electricity from any source creates varying levels of environmental damage, including ecosystem disruption, water contamination, or polluting gas emissions. If we reduce energy use, then we reduce these environmental impacts.

We make choices about our energy use based on how we feel about conservation, the environment, and convenience. Reflect on your energy use, and review the following resources:

  • Review the tips at this site for ideas to reduce energy use at home.
  • Review this site for power outage readiness.

Respond to the questions for ONE of the following scenarios:

  1. Power’s off!  
    1. When the power goes out, explain your biggest inconvenience. What do you manage to live without?
    2. If the power is out for 3 days or more, what are your main concerns? What are the absolute essentials? How do you know food is safe?
    3. Explain what the best back-up source for a power outage would be (for example, solar panels, a gas-powered generator, or even a power inverter for your car).
      • Include 1 benefit and 1 drawback. What is your back-up plan?
  2. Power’s on!    
    1. In the U.S., heating, ventilation, and air conditioning accounts (HVAC) for 48% of home electricity costs (DoE, 2018). Describe one behavior you can change to reduce heating or cooling energy use.
    2. Americans pay 9% of their electricity costs for lighting (EIA, 2018a). Explain how changing all of your light bulbs to LEDs can help save energy.
    3. On average, 18% of home electricity costs go to heating water (EIA, 2018b). Describe one way to reduce hot water use. How easy or difficult is this to do?

chose one: you’ll politely offer your opinions on which proposed law would be most likely to be enacted and why. Make sure to address comments your group members may have left you. between 150 to 200 word onlay for one of the proposed law below:

needed in 5 hours please.

 

 

 

1-Earth is a planet that people have to take care of, if people do not take care of it now, we will see the consequences in the future. Global warming is a problem that has been seen since many centuries now, and it will continue to be a problem if people do not make smarter choices. One of those smarter choices could be an alternative and safer choice when using gasoline for cars. Some researchers at the University of Cincinnati have researched about another better and safer choice for fuel, which includes coffee beans. A lot of car brands have started to use biofuel cars which are somewhat better for the environment than other cars. The United States is a country that should invest and also countries that have big populations. This will help clean the environment clean. The proposition that the University of Cincinnati made, is a good one and so is the one on the video about biodiesel in London. People would still be able to drink coffee but instead of the leftovers of the coffee beans, it would be used to make biodiesel out of it. We would have a better environment and promising future for everyone.

2-To discover a new law, is a rather difficult to answer and discover. As a construction management major and being in a construction course that talks about being sustainable, I would like to find innovative ways that would help a construction site be more green and eco-efficient. It is really difficult to think of something because of everything that is involved within a construction site that it would have to be in a budget. It can go both ways as being expensive or cheap (or a reasonable price). One idea is that there should be a possibility of running all (or at least some of the construction vehicles) run on electrictiy. As modern vehicles have grown towards fueling on electricity, which has really improved the environment by not producing toxic chemicals into the air, but also the fact that electricic vehicles have gone more miles per gallon (MPG). A majority of construction vehicles today run on diesel fuel which realeases toxic chemicals into the air which affects wildlife. Another good possiblity is that there should be greener routes for transporting construction materials which long routes may cause more emmissions into the air. Summary: make construction vehicles run on electricity and find alternative routes for transporting construction vehicles to and from the construction site.

1. Damon Lancaster

  1. Were you surprised at the current size of the human population or at its changes since your year of birth?

Honestly I was kinda shocked at how the population has changed since I was born. I was born in 1999 and according to Ined.com there were 308,978,000 people on earth the year I was born. Just  twenty years later and the population has multiplied by 1.19. There are 366,601,000 people living in Northern America today. This means that in that twenty year time span there were approximately 57 million people born.

  1. How many people do you believe the Earth can support without dire environmental damage? 

I believe that earth can support everyone’s basic needs but the problem is when people start to get avaricious and start thinking of only themselves and taking more than they need not the next person.

  1. Should developed countries help slow the population growth of developing countries? If so, what sorts of methods should be employed to do this?

I don’t think developed countries should slow the population growth of developing countries because we all have different beliefs and morals. For example, if we were to adopt China’s One Child Policy many Americans would not be very pleased with this because they would have to lose their child. According to an article written by Kristen Bialik on Pew Research the average household has “anywhere from 2 to 3 children in it”. After doing more research on Statista.com I found out that there are about “7.13 million families with more than one child”. This policy would affect this nation tremendously.

2. Most of the electricity which is used in my area comes from a dam on the Chattahoochee river.  There are two dams on the river which are the Oliver Dam and the North Highland dam.  The majority of the power that is used in my area comes from the North Highland power plant.  Where I live, Georgia and Alabama are very close.  The river is a natural boundary between the two states. The two dams are owned by Georgia but it is shared in respect to the power distribution.  Alabama Power has transmission lines which come from the North Highland dam.  Although the river provides power to the power plant, there are effects from the dam on the local ecosystem. The two dams block the natural flow of the river thereby trapping sediment, logs, and nutrients which the organisms in the river need.  The river beds are disturbed by the build up of sediment and other things which harms the spawning of the fish and hinders the other freshwater creatures.  Not to mention when the flood gates open, the force from the rushing water pushes away any creatures that are close to the churning water. The damming of the water actually decreases the water’s quality.  The water which comes from the river is turned into potable for the local communities as well.

  It is even believed that dams cause water born illnesses, global warming, and even earthquakes.  The artificial reservoir changes the ecosystem upstream.  The lack of oxygen in the dammed water does allow for the natural plants and animals to survive.  The organisms upstream and down stream both have to adapt or die.  All in all, a dam may help provide power, but the organisms in the river and the people using the power are feeling the direct effects of the dammed waters.  Really the only solution would be to not use the dams for power.  Maybe one day the benefits of having a healthy river would outweigh the need to draw power from the river.  Personally I like having clean lakes and rivers.  Removing the dams would allow the river to become cleaner and thereby making the environment healthier.

3. I live in Valdosta, Georgia which is Lowndes County. After using the energy map I found out that there are 2 petroleum power plants, 2 solar power plants, and 2 biomass power plants in the Lowndes County area. I like that there are 2 solar power plants because while they are expensive to build, they do produce clean energy. However, between the biomass power plants and petroleum power plants my main concern is air quality and the affects that it is causing to the o-zone. I think a way to reduce some of the impact would be to look more into solar power plants, we do have two that are in effect right now so we know that they obviously work but maybe we can rely a bit more on them. I think it might be hard to completely rely on the solar power plants because they are weather dependent and expensive but it would be a start to cutting down the negative emissions. During months when we have a large sunlight exposure we can use the solar energy and months when we are not able to use solar energy we can turn towards the biomass source since it is less of a pollutant than fossil fuels like petroleum. I think that over all the cost of the changes would be worth it. It may be a bit expensive upfront to make these changes but in the long run it could have a positive effect and return of the money that was put into it.

4. I recycle everything that can be recycled here in Columbus, Georgia.  Such as papers or cardboards, plastic (even bags).  Mostly I use the curbside pick up that comes around with the regular waste removal or if it is too big a local park has a large recycle drop off.   When I moved here I discovered they did not recycle glass which I found really bizarre and bothersome because I think glass has a lot of uses.  Just a few would be for countertops, being recreated as another type of container or if it is ground and used as an additive to other products.  I also discovered that some types of plant containers (non decorative) sold at our local home improvement stores are not recyclable.  Which with such a broad distribution seems wasteful.  I think its useful to recycle overall if it reduces the impact on the environment.  However, if recycling becomes better for our soul than the actual environment then the entire premise would be moot.

5. Dalton, Georgia is known as the carpet capital of the world and with that being said the carpet material that is leftover should be recycled. It can be left at the carpet plants and the workers can break it down and reuse it. Almost all types of carpet are recyclable. Depending on the makeup of the carpet, it can be broken down into fibers, or plastic pellets. The leftover carpet and materials can be recycled into new carpet or new construction projects. It is worth recycling in my area considering there are so many carpet plants, roughly 150 of them.
