Unit 8 – Assignment, environmentally sustainability, reflection


Introduction
On our planet are many environmental problems. We discussed a lot of the most pressing problems of our world in this course. We learned about health problems which are a result of the exponential increasing world population. We learned that the southern hemisphere of our planet – especially Africa has still significant problems with chronic and lethal diseases. But also the developed countries like Europe and America has major issues in water pollution.

I learned that a comprehensive view overall topics in this course the whole apparatus of our planet is a big cycle. All problems are a logical result of other issues. Maybe, some obstacles lead to the none solving of the root causes. For much problems of our modern civilization, people just integrating workarounds and non-sustainable solutions. But this results in other issues. The work on quick and dirty answers result in an endless cycle until the people begin to think and integrate real solutions which are solving the cause.

First of all, I would try to improve the public transport system in my city. Optimize bus lines and integrate strategies which could improve the usability of our system. Later we should focus on improving the parking and street system. Much planning makes at the moment no sense here. Many one-way streets and senseless traffic guidance also makes a heavier traffic and result in detours of this.

We have a lot of road signs, about the half of them are not required.

After improving the traffic system, we can integrate greener areas in our city. Just more lawns, green areas, and plants result in a better feeling of the people and make them happier. Green areas also have a positive long-term impact on our air pollution. Wes should optimized use all possible areas. So we can use the roof of flat buildings for growing some plants and also use facades of buildings. We can develop a system to use the facades without destroying of the surface and protection against moisture accumulation.

A possible step is also the try to use regenerable energy sources in my city. We can move step by step to solar power for public buildings. Why not use the roofs or free space of the governmental buildings to produce cheap and renewable energy? The government should be an example for public problems. For our street lighting, we can use solar street lamps. The investment costs are after some years above the break-even point. The savings are much. Every night the street lights consume much electricity which is a good example of the senseless waste of energy.

In Germany, there is a good example for preventing innovative solutions. My former boss tried to implement the solar lamps in Germany, but the buro-crazy and ununderstandable regulations prevent it. The problem was that our law says a street light require a connection by cable to receive energy. So, why this on a solar lamp which should work without wired power? We could make dispute that in the case of battery problems (which is usually impossible even the battery is without function) we have a backup powering of the lamp. But on traditional street lights, we often have defectives. We have also light on cars and if one single lamp lights or not does not concern. It is easy to implement a self-diagnostic solution in the street lighting, and a, for example, secure system for self-controlling via RFID or just an indicator led on the light case with the battery status is easy to apply and also to check. A regular check in intervals is no problem and just cheaper than powered solutions.

Conclusion
We have many options. Also, we have people who are thinking sustainable all over the world. Some inventions are ready for use and testing, but it lacks on our government. The government is often not considering reliable, or the government can not handle because there are law regulations which prevent the integrating of innovative solutions. So our law is against our self.
The people should also begin to handle; they should break out of their treadmill and began to change (break out) some laws. If we are work together, we can do great things and find appropriate solutions for significant problems. Big problems often require massive changes.

Just do it.

Assignment: The water cycle around me


Earth is the only planet in our solar system that provides a suitable environment for life as we know it. Sustaining these conditions requires a constant recycling of materials between the living and nonliving components of eco-systems.

Select one of material cycles we studied (water, nitrogen, carbon, sulphur and phosphorus) and identify elements of your lifestyle that impact the cycle.

a.    What are the most considerable impacts you make?
b.    How might it change your life if you were to reduce your impacts? What would you need to give up?
c.    How difficult is to balance personal choices with environmental considerations?

Your answer should be between 700–900 words long and should include introduction and conclusion sections.

The water cycle around me

Introduction 

Every human in the world has a significant impact on the water cycle, as well me. Every day I use resources and have a major impact in into this cycle. We often use resources without thinking much about it. It is simply normal to us, that enough of these resources are available for the people. Water is just always available for us. 

At every day that I take a shower, take a bath, cook with water or just go swimming in a sea I have an important influence on our water cycle. Water which I use comes from our community water supplying system. 

This water has been cleaned from bacteria and so on. This water is from reservoirs filled by the rain and ground water. It does cost much work to bring the water into my home. The used and dirty water from my home goes back into this cycle after a recycling process.

To produce our daily life products like plastics, food and the most of all products, water is required. 

The pollution from this production has also impacted the water cycle. Also, pollution of, for example, industries and traffic make the rain acid. The acid rain falls and makes the plants ill. Also, the groundwater could be polluted from chemicals and other toxins if I do not care about the deposit of waste or buy products which are created from plastics.

So, every time I use a product created from plastics or produced with water, I have also a major impact on our water cycle. If I don’t take care about of our environment and for example don’t recycle waste I impacted our water cycle.

I consume a lot of electricity in my home, every day. Electricity requires to a whole part, fossil fuels for producing in power stations. There is also an impact on the water cycle – the stations use coal for example. There is an impact to the cycle because coal is mined in crafts. If there is less coal in the soil, the water is less filtered and not as clean as before. The trees can’t grow on the crafted soil. Fewer trees produce, less condensate. Less condensate produces less water in the reverse.

My life changes significantly if I try to reduce my impacts on the environment because I diminish my comfort. Maybe I think deeper about the consequences, of my personal actions, maybe more concrete about the products which I buy in a supermarket. I could think about the production steps of a product or how many toxins are being released in the economic cycling after or until producing the product.

It is hard to find a wise way for the environment next to my personal lifestyle. If you worry too much about our environment we lack in personal comfort; if we take to less about our environment we shall experience in the future maybe the consequences of our personal lifestyle. Also, our personal budget is an essential factor in environmentally conscious thinking.

But, if all the people don’t take care of our environment, we get wicked results, like global warming, toxic water and so on. So, we should find a middle way of this.  

Conclusion

Yes, I can change some behaviors to reduce the impact to our water cycle. I can take a shower instead of taking a bath to reduce the amount of water I use for my personal hygiene. I can try to reduce the amounts of waste from plastics (much water is required to produce). I can use also public transport instead of my own car to reduce the emission of greenhouse gasses.

A big impact to the water cycle has the energy consumption of my electronic devices and light bulbs, which is easy to reduce.

I easily can reduce the amount of consumed energy in my home with installing energy saving lamps or LED lamps to reduce the amount of energy used in my home. I can switch off devices if I don’t use them actively because devices sometimes use energy in standby mode.

The selection of an electric supplier, which use renewable energy sources, like wind or solar could also have a positive impact on our water cycle.

My personal target in the next months is to find a reasonable way to have an average level of comfort next to sufficient and average environmental considerations.

Hello,

1. What is this report about?

The report is about climate change, the reasons for a climate change and tries to handle the problems of climate change by the government and the influences of the government to third-parties.

2. What climate change vulnerabilities are identified for your region?

Greenhouse gasses are a big problem. Pollution from the cars has a major impact on our environment. Also, water pollution is a more and bigger problem.
3. Did they surprise you? Why or why not?

# No it does not surprise me because the car companies also faked the customers and government about greenhouse gas emission of the cars. The people do not use public transport systems because there are too lazy…they always want cars, bigger cars with more power. The car companies also not interested in making effective solutions for the oil problems because the oil companies always want to make money with the oil. It is a big cycle and problem.

4. Describe (in your own words) three adaptation measures that have been for addressing global climate change in your region.

There are tries to recultivate an old military training place in a town near me. But a real recultivating or adoption measure they not trying to improve the water problem here. The storage of water has an impact also on the environment.

They try to improve the greenhouse gas emission with alternative energy like gas stations or electric energy stations for e-cars. But it is not cost effective.

5. In your opinion, which one is the most important? Why?

# Recultivating polluted and wasted areas in our county is one of the most important actions they should do. The water is stored in sees but the water is still. They deactivated the water flow to hide the truth here.  A first action to improve the water quality could be the reactivation of the water flow with activating the big river. They deactivated the river many years before.

6. Outline two steps you could take to lower your climate impact. Check the Union of Concerned Scientists for some ideas.

# They can try to improve the public transport system and reopen the train system here. They closed many train stations here and that’s a problem because bus also has a pollination. A try could be also to use more alternative energy like electricity or gas. The problem is that are not enough electrified or gas stations here.

Also, the industry could focus more on alternative energy but they don’t do. Maybe the problem is the power of the lobby?

Sincerely,

Michél


 

Go to this website, which is hosted by Skeptical Science. Read up and then answer the following questions. http://skepticalscience.com/argument.php

  1. This link covers many of the myths about climate change.
    • List two of the myths that you found most interesting.
    • Outline what each myth is, and what the right answer to that question or item is.
  2. Has your view on climate change evolved since before taking this course? Why or why not?
  3. Choose one the Review Questions from this week’s readings and answer it in full.
  4. Please tell me how the course is going for you so far? Is it hard, “just right”, or easy?

1. This link covers many of the myths about climate change.

• List two of the myths that you found most interesting.

• Outline what each myth is, and what the right answer to that question or item is.

I chose the myth number 23.: “Does cold weather disprove global warming?” (Meador, n.d.).

Cold weather comes mostly from the wind and the current distance from the sun to the earth. Also, the wind comes from gravitation waves and the status of Phi. The reason for the gravitation waves is the current power of Psi and Omega resulting in Phi.

So the global warming is a problem, sure. But the rotation of the planet and location in the universe of our planet is mainly a reason about the status of Phi (Picker, 2016).

So we can conclude that the actual location of the earth is a factor for global warming, the wind also has an influence on this but also the destroying of the ozone layer which prevents the earth from alpha radiation.

2. Has your view on climate change evolved since before taking this course? Why or why not?

Yes, my view has changed significantly because I now opened my eyes and view more critically to some facts like climate change and energy sources and the energy cycle. I now know that some problems are made from the industry because the government wanna change but can not do.

Now I knew where we are from and have knowledge about the whole cycle of the energy. The energy is all made from light. And some other. The course opened my eyes.

3. Choose one the Review Questions from this week’s readings and answer it in full.

I chose the review question:

“What are the pros and cons of various waste management strategies? Do you agree or disagree with the general waste management hierarchy?”

It depends on the specific strategy a government in a specific country are using. If a community, for example, incinerates the waste at high temperatures emission and pollution is released into the environment. The incinerator could adhere to a filter system but there is always a rest. Buring waste with zero emission is with this method not possible. There should be a system with zero emission. The waste could be changed to waste with a specific wave height with zero emission. So there should be a “transformer” system which changes the wave height /gravity of the waste to a specific level so the waste is gone back to its basic matter/light.

Recycling is okay, but it lacks in the basics. What do they in our community with the waste? They fire it and do not recycle it at all. Makes no sense. Why are they not hundred percent recycle and sell the plastics for example back to the industry? The costs are too high for the industry. The whole system is not effective enough at the moment.

The waste management pyramid is okay but it lacks in a 7th step. What about the waste which we can not recycle, reuse or whatever? Like nuclear waste? They just storing the old radiated minerals. Why not reuse these? Or just turn them back to its matter with a transformation system.

I agree yes, but we should add the seventh layer.

The other question I answer is: “It’s cosmic rays”. Cosmic rays show no trend over the last 30 years & have had little impact on recent global warming. Question number 21.

It is true. Cosmic radiation (mainly Alpha) (Picker, 2016) is increasing because the ozon layer devastation  goes still on in the last decends. Radiation has no impact to the global warming. The problem of warming is the trouble between the two quanta animals, the chaos in which the two animals are in a specific orbit. The more heat of friction is between the specific amounts (N) in a orbit Ox in a room Rx is the more friction heat will be free (Picker, 2016).

4. Please tell me how the course is going for you so far? Is it hard, “just right”, or easy?

For me, it is still hard because I have not much time at the moment to focus on the study at all.

I look for an appropriate job at the moment and have to push my projects to the public. But it is okay., that is my problem :).

Unit 5: Sustaining Energy Resources


  1. What does the term “renewable” mean?

Renewable means in this case that the source is endless like a “Perpetuum mobile”.

The energy is endless normally. Energy is a product created from other sources. I explain it on an example. If we light a fire the heat is the energy which is before in the wood. The wood has been grown before, the wood lives – ATP (adenosintriphosphat) is used as energy of the cells to grow and live. The ATP is produced by photosynthesis (maybe) and photocatalysis from the energy around.

If we fire the wood, the heat (energy) goes back to our environment and goes back to the environment. After it is gone to an environment the energy goes back to outer space and changes the wavelength because it changes the speed.The speed of the light is changed because our earth is magnetic.

So the changed light spectrum is not visible in outer space.

We can explain this with the “fata morgana” phaenomena. It is a little black hole what show us the opposite or the end of the black hole. We can also name it an anomaly of gravitation.

So a renewable energy source is a light. Because light is Energy of a specific wavelength.

So every source is a renewable energy source because energy is not lost. Only the aggregate condition has changed. But maybe we are all building from light?

 

  1. Which two renewable energy forms did you choose?

We only have gravitation normally because no change of the wavelength is required. We can use the already changed light/gravitation – Solar cells are catching the Gravitation/Lambda of a specific length.

So maybe we can use also Gravitation as an energy source. I would like to prefer this. But it is not available so I chose maybe wind because is also effective.

We can use the gravitation to create a machine which forms the light to electricity. We can build a transformer which changes the wavelength to E^2.

 

  1. For each, describe two benefits.

Solar is the best because it is present. So just a catching of energy/light/gravitation without destroying the gravitation of a lifeform. Don’t harm our environment and is effective and simple to handle.

 

  1. For each, describe two drawbacks.

Solar technology is not optimal realized maybe the storage of energy is not so good. We should focus on a better storage solution.

The technology is too expensive at moment.

The transformer has no drawbacks. Maybe it is expensive to build one and the people do not want it at moment.

  1. Which of these you feel would best serve your community? Why? Explain.

The transformer because we can use it in the night to make light.

It also does not need to change the gravitated objects like wood and so on and has no economic impact.

  1. According to The Energy Report prepared by WWF and Ecofys, “by 2050, we could get all the energy we need from renewable sources.” What is your response to this statement?

That is true, but it depends on the people and the support of each other to change something. If we can use our skills to develop a better source and make the methods for electricity cheaper then we should do that. Why not? Not wasting the fossil matter just use what we have.

M = λ = G * C = E^2 * Mc² = G

G = λ

EE or E² ist the Energy on Earth  = c * λ in S

c * λ = E² ist the Energy on Earth = light of a specific wavelength  in a room S on earth

S = a room r3 with an Element-X

Z=A Element 5 which changes the wavelength and state of matter.

G=Gravitation = c * λ

c = Speed of Matter

A>= c * X in Room S = E² *M

Y = Gravitationwaves + H

H+ = power of the planet movement in R

R = Einsteins Room

G = Gravitation

λ = Constant of  Einsteins Universe = is the wavelength/Spectra of light

M = Matter

M = λ

1. Summarize, in Your own words (do not copy from the website) two of the methods for sustainable agriculture from “Solutions: Advance Sustainable Agriculture: Using science-based practices, we can produce abundant food while preserving our soil, air, and water” including all hyperlinks used.

Sustainable agriculture means often the renounce to chemicals and herbicides for farming/agriculture use.
The farmers can do that with classical methods like rotating of seeds and crops. Crop rotation every year is a often used method that our farmers in Germany in most cases do. The advantage of this is that the soil can regenerate in the time until other crops grow.

The use of natural fertilizers is a well used practice in my country and have much benefits. Since agriculture of the humans exist, the people use natural fertilizers. The soil is not polluted through chemicals and there’s no big impact like the use of chemicals. Also the advantage is that no unnatural fertilizers go in our food cycle.

My suggestions are: Also possible methods are, the use of the whole plant as a possible solution, I think. We should use every ingredient from a plant and use it as a delivery service for medications for example. Chemistry alone and chemical synthetical compositions are not always the best solution.

A reason is that we should combine natural ingredients for a sustainable effect.  We can combine different characteristics like apples and chili. Apple for eating and chili as a barrier against pests.
We also shouldn’t eat the source for other food. Like chickens. They are our supplier for eggs. So why eat a source of food?
That is sustainable.

2. List one method that you think would work well in your local village/town/region. Why would it work well? Explain.

I think all of the above methods could work.
The farmers in Germany already using the most of the advanced agricultural methods to improve the natural sustainable cycle.

My suggested methods also can work here. We can habitat the plants for natural Pest barriers for example also in most of the countries.

3. Please outline in your own words, one other new thing you learned this week in the course. How does it apply to your life?

I learned that not all is like we think. If we do not look closer we can not find a solution. If we do not understand the basics we can not find a solution. Some views are often not the real true. Sometimes our point of view is not the correct. Science depends often on our point of view and the impact of the industry to he government.

Unit 8: Sustaining Human Societies


Hello,

please find my answers below for this week’s discussion assignment.

1. I think the most influencing change is Curitiba’s public transport system. It has reduced the heavy traffic resulting in personal transport with cars.  Reducing of the private transport in the city has a positive impact on the pollution of the air. It also is a sustainable solution which increases the livability of the city  (Gnatek, 2013).

2. The county of Paraná has a lot of universities. Why not make one big school to lower the administration costs and gain a higher efficiency in the structures?

Another idea is maybe the automation of some government processes – much countries already try to improve these processes and try to move to more and more self-administration via the internet. But it lacks on transparent processes and planning. Optimizing of these processes could be an improvement which is helpful to reduce time and money waste. Also, it is a greater comfort for the citizens.

A more important step could be the move to “free energy.” If we change the power of the used electricity to a non-harmful level (which is possible!) or move to D.C. (direct voltage) which is not harmful to the people, then we can introduce a “free power.” Free power means the distribution of power energy without the requirement of cables. To move to D.C. power at all is no problem if someone with excellent planning skills does.

The people could not be harmed from D.C in such a scope as the alternating voltage does. Thomas Alva Edison ‘s problem was the distribution of the electric energy through long distances, so he and Tesla moved to A.C. as a workaround. Also, the industry would earn money from electricity. If we have free electricity in the environment, the electricity producing companies cannot count them.

We can improve the voltage of the electricity to gain higher distances with D.C.

After the introduction of free energy, we can use this as a fuel for urban regions. The public transportation system could be powered by that fuel.

Also my former boss, and now friend developed a system for self-supporting street lights. They need no cable and connection to whatsoever. The lamp gives light for about three days also without direct sun emission. It could help to reduce the high costs in more rural regions. Also, it saves energy costs.

3. Not only one solution could work in my country, but all of the solutions are also possible for my town and country. Like the public transportation system. If the public transit system did work more efficient, the more people would use this transport system. If more people use the public infrastructure, also the costs go down.

My county has a lot of little towns with long distances to the next town – the problem is bus transport is not efficient. A few decades before, every small town had a train connection. The problem is that they now removed the most train connections. Fewer train stations – fewer users. But the decisions makers do not understand this simple rule of business.

There are many current projects around the world to support sustainable development and growth in urban areas. The general goal is to create livable cities in which people have open spaces, nature, and areas for congregation and relaxation. The idea is also to have well developed public transport systems that would reduce the need for cars and other transport that contribute to air pollution. Through good education programs there can be less litter and reduced waste. Finally, thoughtful use of more eco-friendly products, renewable energy, and materials can make a huge difference in reducing both waste production and energy use. Basically, cities can be built and developed in a way that is healthy for the local environment as well as those living within the city. Curitiba, Brazil, is a city that has become a model of sustainable city growth and quality urban planning. At the following links you can learn more about the different ways in which Curitiba, and its mayor, have supported sustainable, environmentally friendly, urban growth.

Read and learn about this city at the following links and the textbook, then answer the questions below:

Questions to answer:

  1. What is the most significant change or project in the city of Curitiba that you feel has influenced it becoming more livable, clean, or sustainable?
  2. What do you think the future steps in Curitiba should be? For example, what would be a good ‘next project’ to continue their movement forth in sustainable development and quality urban planning?
  3. Do you feel that any of the planning, projects, policy, education programs, and/or changes they have made would work well in your own city? Which one, and why? Explain.

Hello,

1. Please list two bits of information, statistics or facts that you found at some of these links which interested and/or surprised you?

It is new for me that every day 2 million of sewage are going into our water cycle and the people die from the polluted water (United Nations, 2015).

This is a big problem and should be solved soon because the water is most important for the human life. It is a bad cycle because polluted water also goes into the atmosphere which results in acid rain. The acid rain disturbs the plants from growing. Fewer plants result in less oxygen production.

One-fifth of the population of the world lives in regions with physical scarcity to water  (United Nations, 2015).

2. Explain, in your own words, what the difference is between water quality and water quantity?

Water quality is the cleanness of water, the specific pollution of toxins or pests in a specific amount of water for example. Quantity means the amount of water which is available for use.

3. Is water quantity or quality the biggest issue in your local village/town/city? Why? Explain.

In my town is water quantity a bigger issue than the quality. The quality of water is in Germany very good. We have good waste water treatment plants here. The issue is that water here has a long way to go, it comes from some storage seas in the near, next to pipelines from other treatment plants. The water supply companies store the waste water in big cisterns for further cleaning. After they clean the water it goes back to the fresh water cycle. “New” and fresh water is supplied from other seas in the near and wells. So the amount of water is always a problem. Also, it is very expensive here.

4. Are there disputes, violence or wars over water in your local village/town/city?

No there are no disputes, violence or wars or something similar about water in my town. Also not in my country.

5. Look up what IWRM is: define it.*

I have the understanding of IWRM that it is a process which coordinates the use of the water in different branches. We have different use cases of water with different priorities.

We have for example water for the people – for life, drink, washing and similar activities. But we also have the industry which uses water for the production of goods. There are also two other use-cases, water for food production and plants.

IWRM means here in my understanding that the organization coordinate the use of the raw water in these four branches and make sure that the whole cycle of water goes correctly as planned.

Next to distribution of the water, the IWRM also plans the cleaning of the water (“What is IWRM? – THE CHALLENGE – Global Water Partnership”, 2016).

6. Would IWRM work to help water issues in your local village/town/city?

Yes, I think the method could be work in my county and help to optimize the water flow and reduction of the costs.

Dear Andrew,

thank you for your statement to the question of our instructor.

I agree with your meanings. I think the problem of water availability is a big problem in developing countries. The few water well’s in Africa, for example, are controlled by some companies, like Nestlé. They sell the clean water to the people. So they are dependent then.

Money is often a problem, also for industrial countries, the companies often want a margin for their services. They clean the water and this is cost effective, surely. But the problem is the big margin they often calculate in the costs.

Such services should be government controlled, not private.

Sincerely.

Michél
