Unit 8 – Assignment, environmentally sustainability, reflection

Environmental science


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 of 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 many 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 results in an endless cycle until the people begin to think and integrate real solutions that 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 that 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 make heavier traffic and result in detours of this.

We have a lot of road signs, about 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 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 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 of 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 of 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 a 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, a 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 interval is no problem and just cheaper than powered solutions.


We have many options. Also, we have people who are thinking of 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 it because there are laws regulations that prevent the integrating of innovative solutions. So our law is against ourselves.
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 working together, we can do great things and find appropriate solutions for significant problems. Big problems often require massive changes.

Just do it.
