Complete Course DQ’s Weeks 19 for SCI275 Week 1 DQ 1 In your own words, define environmental sustainability. Then, list three behaviors of your own that threaten environmental sustainability. How could you change those behaviors to reduce threats to environmental sustainability? Environmental sustainability would be the ability to use natural resources without effecting the environment of the area. The first thing I would list is the use of fossil fuels to travel. Since I live over 15 miles away from where I work I use a lot of gas. Apart from helping the world consume the little bit of fuel left I am adding to the pollution with the exhaust and emissions from my truck. The second environmental threat I am involved in would be the use of aerosol cans. Hair spray is the main one used in my home, personally I do not use it but since I purchase it for my wife and children I am just as much to blame as they are. Lastly I would have to say that since the price of dumping garbage is outrageous I am helping pollute our environment because I try to burn whatever I can to keep from paying more at the dump site. However, if you look at it the right way it is either burn and pollute of dump and pollute, both ways are potentially affecting the environment. The landfills we are creating are only getting bigger, filled with items that will not dissolve for many years to come and making the ground unusable. Week 1 DQ 2 Reflect on your own worldview and compare it with the worldviews presented in the text. Provide examples of the benefits of your view to defend your position. Although I do follow the western worldview to a certain extent, I would have to say that I do follow the deep ecology worldview. I am a firm believer that all things should live in peace and harmony and be well balanced, which the world is not and probably never will be again. I was raised to live off the land and only use what was needed. We raised our own cattle, pigs, chickens, vegetables and even spices. I still have my own garden and give away what my family does not need; however, I do live in a rural area so raising animals is out of the question. I do have friends who bring wounded animals over to my house all the time and I will mend them until they are healed and then release it back to the wild. This is always gratifying when this happens, I am a firm believer in do not kill what you do not plan on eating. On the other hand I do indulge in the technology of today and will probably continue doing so until I am six feet under. I only buy what I need though; I try not to over indulge myself or my family in the finer things. Hopefully my children will this when they are grown and leave my house. I feel that if the whole world can work as one we might be able to change some of the tragedies happening to our planet, such as animal extinctions, pollution, over population and so forth. One can only try and do their part and spread the word when they can. Week 3 DQ 1 Identify the fruit or vegetable you selected and relate the second law of thermodynamics to the changes in energy observed in Appendix C. How did the amount of energy gained compare to the amount of energy lost as heat at the second through fourth trophic levels? Considering the amount of energy required to produce animalbased foods and goods, should humans change their habits so they consume products closer to the bottom of the food chain because it is more efficient? The fruit I chose was a mango, then from the list of related foods I chose mango, raw. The calories produced by this particular fruit was 107, however it was mainly the sugar content that gave it a high calorie count. The amount of energy gained by consumption was insignificant to the amount of energy loss, at a 10 percent gain by consumption the loss is at 90 percent. So in my opinion it takes more energy to create what the human race consumes compared to the energy gained by consumption. This does not mean that the human race needs to or even should change the diet. If we take into consideration the world’s population and a changing diet to try and consume the items located on the bottom of the food chain list, we might just have a catastrophe on our hands. With all humans eating the greenery the population of game animals could grow to overrun the area they preside in. This would throw off the ecological balance of that area force humans to take action “again”. However, with the world population being so high, it seems that no matter what we do it has an adverse effect on the ecology of our planet. The best thing to do would be cut down on the population of humans. Week 3 DQ 2 Use the Ch. 6 Biome animation located under the Week Three Materials section of your student web page to identify which biome you live in by clicking on the colored area of your general location. Post a brief description of your biome by responding to the following: Provide a onesentence description of typical precipitation and temperature for summer and winter. Use terms such as cool, cold, warm, hot, dry, and wet. Then, identify the characteristics of a plant and animal that is seen regularly in your region. How do the characteristics relate to the amount of rain or sunlight in your region? When responding to your classmates, explain how the traits of your plant or animal may or may not be adaptable to their biome. I live in south Eastern New Mexico and I would say that we have a strange biome, while being desert the climate says something different. The winter months are very cold, most of the time below freezing and the summer months are very hot with quite a bit of moisture. There are various desert plants which require very little water to survive but the most recognized is the yucca, it is located everywhere something has a chance to grow. The animals seen most often here are skunks, jack rabbits and coyotes. Since these animals are everywhere you see them during the day as well as the evening hours, it could be that I am an outside person and am always fishing so I see them more frequently than others. They are all very timid animals except the skunk; they seem to be a very curios critter. Every encounter with them is quite exciting, I like to watch them and see what they are doing, I even walk with them along the roads or the canals until they get spooked and run off. While most are afraid of skunks I find they are misjudged and really pose no threat unless someone threatens them. Week 5 DQ 1 Go to the Emissions Calculator Web site at http://airhead.cnt.org/Calculator/? sid=a743a150a5f5ff4c72817e723b7c8c14 Fill out the survey to the best of your knowledge to calculate the total pounds of air pollution your household emits. a response to the following: What was your highest contributor? What can you do to lower your total? What is your greatest challenge in lowering your total? When you review other students’ posts, suggest how they might control air emissions for their situations. While the average person emits 1654 pounds of toxins into our atmosphere, the calculator says I am releasing less, about 1138 pounds a month. While I think that is pretty good, I also think that I still have a lot of room for change and lowering that number even more. The biggest contributor I currently engage in is from the emissions from my truck. Although this test is a general overall view of what people contribute, I feel that the numbers calculated for my truck are a little low. My truck in not the normal V8, since my family likes to go camping and I personally enjoy going fourwheeling, I purchased a truck with the V10. Maybe not a good idea for the environment but it is fun to drive. While living in the country and working in the city, I drive quite a bit back and forth to work, buy groceries, and enjoyment. It would be great if there was public transportation available here to take me to and from work, but unfortunately there is not. So I would have to say that my biggest challenge would be to stop all the needless driving that I do. I could even sell my truck and buy a smaller vehicle that is equipped with four wheel drive also, such as a jeep. Some of the jeeps are equipped with a V6 so this would drop my emissions by about 3/8 ’s a month. Week 5 DQ 2 Review the variety of indoor pollutant hazards posted on the EPA Web site at http://www.epa.gov/iaq/pubs/insidest.html#Refguide Post your response to the following: Describe at least three potential indoor air quality (IAQ) hazards in your home. What are the possible health impacts of each hazard? Do you believe your health is at risk based on your exposure to the three IAQ hazards? Why or why not? What can you do to reduce exposure to the hazard? The three potential indoor air quality hazards in my home would be formaldehyde, pesticides and lead. Out of all the different types of IAQ hazards out there I would have to say these three are by far the most prominent in my house and probably in the homes around where I live. I chose formaldehyde due to all the furniture we have made out of particle board, i.e., entertainment center, all of our dressers, fish tank tables, couch and lazy boy chair, dinner table, counter tops, computer table and the bottom of the chairs we use. All of these products are made with a certain amount of particle board, plywood and fiberboard in which I was unaware of the health risks involved with owning products like this. The health risks are numerous but the one that caught my attention was “cancer”. This is something that makes me a little nervous since I do have two very young children in my home, both are my grandchildren. The next IAQ I have in my house would be the pesticides, since we live very close to the local dairies, flies are a major problem. It seems that during the summer months I spend more of Raid for flies than I do on gas for my truck. However, by reviewing the hazards involved with using these chemicals I will take necessary steps to avoid using them in the future. The health effects say that there is an increased risk of cancer and damage to the central nervous system and kidney, ouch. I think it is time to change how I eliminate the problem with flies. The last IAQ I have in my home is lead. This is generally from the paint used around the house and inside the water. The water can be an easy fix, all I need to do is install a filtration system to clean and purify it before use. The paint on the other hand is a different problem; it seems that the particles in the paint can affect a person when trying to remove it as well as using it to paint. When one removes paint it needs to be scrapped off causing dust particles, this in turns releases the lead and one can breathe it in. I think that I will just leave the paint that is already there and not worry about it until I need to. As is stands the paint problem should cause no problems, however the water still can. Lead poisoning can lead to death if not reduced to the proper levels that the body requires. Lead can also cause severe health problems and even death if it goes below the required amount the body needs to function. I say one needs to just monitor the daily activities of one’s family members and note any changes. If changes are seen in any family member then take them to a doctor and find out what was the cause and fix it. Week 7 DQ 1 View the Don’t Say Goodbye VLR located under the Week Seven Materials section of your student web page. Post your response to the following: Identify a viewpoint given in the video that highlights the importance of biodiversity. Do you believe that every species is connected to one another as expressed in the video? Why or why not? A good viewpoint in the video is when Tom mentions that more than half the medicines we take have come from nature. Everything that is out there could hold the key for a cure to cancer, aids, or other terrible diseases. The need to keep looking and checking plants and animals is big, with all that has been found, there could be more. If one was to look at areas where animals have become extinct or on the verge of extinction then we can really see the extent of how connected we all are. By over hunting the seals we have taken away the very food the Orca eats. Now they are feeding on other animals such as the sea otter, which feeds off of crustaceans in the kelp fields. With the low population of sea otters the crustaceans are overrunning the kelp fields killing the kelp. This type of example can hold true for any organism on the planet, kill one off and the next in line that depended on the first will soon die as well. So I would say that everything is tied into one, with the loss of one comes the loss of others until nothing is left. Week 7 DQ 2 Choose one of the following terrestrial resource challenges: Loss of agricultural land Reducing solid waste Post your response to the following: What are the challenges of managing your chosen terrestrial resource issue? What human activities contribute to the problem? The terrestrial resource issue I have chosen to discuss is the loss of agricultural land. As we all have heard and seen the planet is not made up of unlimited resources but we as humans take the mother earth for granted. By overpopulating the earth we are forced to move into other wise small populated or unpopulated areas consuming the very ground that supports the life we have. Our cities of the world are only large enough to hold some of the population, the rest is forced to move elsewhere, develop elsewhere, build, take land, reproduce and continue this cycle as long as we can survive. To manage the remaining agricultural land we have left we need to stop building, stop taking away from the earth and start giving back. Instead of a family having four children, have two and help recycle what you use. Those who have money buy some land; start growing crops not building shopping malls, gas stations, movie theaters, trailer parks and whatever else it is that land developers build. Capstone Discussion Question Week 9 Post your response to the following: If you were an environmental researcher and were given funding to assist with one environmental issue, which of the following topics would you choose to spend your funds on? Human population Atmospheric pollution Water resources Terrestrial resources Energy conservation What influenced your choice? What would the ultimate goal of your research be? The funding I was given would be used in the study of advanced techniques to help control our population. Most of the world’s problems are a direct result for overpopulation, and not just in one or two countries, this is everywhere. With the population controlled our natural resources would last longer, we would create and release less toxins into the atmosphere and the overfishing of our great oceans would come to a stop. If one was to post all the problems around us on a board and try to decipher where the root cause was in the creation of these problems, all the lines would point right back to us. That is why I would go this route instead of the others. I would try to create better birth control, not only for women but also the men. Give seminars on why we need to try and control our population, open up web sites, TV programs, info commercials and even paid incentives for those who want to help in the process of population control. The best way to go about something like this would be a world campaign, involve all countries and get as many politicians to help back it up. This would help promote the idea even better to larger communities. There are countless ways one could help teach why we need to control our population, the main problem would be the funding and if the poverty stricken ones would be able to afford the control methods.
