Eliminating poverty means to be able to supply every human being with the goods to fullfill their basic needs. Such as air, water, food(nutrition), warmth/shelter, medicine, sleep and hygiene.

Besides that we also need light(sun), a stable-enough environment, clothes, social contact, ressources to face future problems.

In the current money-based economy the definition of poverty is mostly based on the costs for an everyday life in a specific region.

Thus we can either get a system running that all people have 'enough' money, or directly supply them with the goods.

​

Zero hunger is almost included in goal 1 but expresses the problem of distribution of agrar-tools, water and land. In some cases there are also problems in growing food because of consistency reasons.

When we deal with the material problems we should build a sustainable cycle. 

On the other spectrum we have a wide variety of problems, from security issues to weather and cultural difficulties. These mostly address the overall living situation of the farming people, but we should have them in mind. 

An overall issue is that the local economy(like farming) has to be cost effective against products from the global markets. I also want to express that we re talking about general solutions for this problem, but it will be brought to action locally, specific and most likely small.

This is one of the hardest goals from my point of view. it is hard to define what global health is and if its ever possible. When i look at the most developed countries(in terms of medicine) there are still illnesses not cured, people dying to injuries and a lot of wrong (especially old) information about health.

But in fact, being healthy is easy to maintain for the most part. The keys for me are good food(enough energy and nutrition), (clean) water, physical activity and hygiene. 

For the medicine: There has to be a set goal of something like " All medicine is available for illnesses that occur in an estimate of 1% of the population in one year". You might add a special, more stricly goal for medicine for lethal illnesses.

There is so much information out there. First of all we should reconsider what should be teached. After that, we have to develop(or just take) teaching styles that encourage students to learn.

Time, effort and will are ressources we have to be aware of, using them wisely.

There s also this (dis)balance between costs and quality of education. One can achieve great quality education with very little money. Information is immaterial and can be shared with no cost but the ressources i mentioned earlier.

The difficulty here in my eyes are the discussions we have to do: To get a consensus what to do. The doing itself depends only on the people though.

Obviously men and women are different, there are characteristics. But its how we deal with these differences. There are a lot of cultural influences or old behaviour, but even modern people have gender equality difficulties. I think there has to be some kind of moral guide, and everyone has to check if he s being just.

On the field of work we have to give equal chances by qualification. But we have to face that there will always be differences.

To even this out, we probably should reevaluate and redefine the worth of a human being.

This is much more technical theme. With that many people on earth, we also need a lot of water. Water waste should be avoided and thus i think we need a regulation. Active with rules or passive with a cost of some sort. New water comes from different sources, but for the amount we need, we should use desalination on seawater. Storage and distribution are the next difficulties. Living near water is easier, probably people will move. I also can imagine floating cities.

Sanitation and hygiene are also important. The waste should be sent to systems that can collect, separate and use it. There are a lot of modern ideas out there already.

This one is on another scale. I thought about production, storage and distribution, but there is the one thing, consumption. When i talk about energy i mean the usable form, mostly exergy.

Energy is easy to produce, but it has devastating long term side effects. 

Until we find the next big energy source, we should learn to limit ourselves. This needs a strong will but i think its a neccessary step towards a long term future for humanity. We really have to think about what we as a whole want to accomplish.

Decent work should be work that doesnt affect our health too much. We also shouldnt be forced to work, but go work on difficulties with a positive mindset.

Economic growth cant be endless until we allow things to fade and take immaterial things into account.

This big tri-field builds around a productive economy. Innovations are new impactful ideas or inventions, fueling our journey to a better life and opening possibilities. Industry is the producing instance for most of the goods. Infrastructure is important for distribution, making resources available where and when they re needed.

Since all humans are human, all should be treated equally. Inequalities are differences so huge that they form own social groups. Problems arise when these social groups fight each other.

Our goal should be to reduce the fighting and that the inequalities are not too big to overcome with kindness. This is part of my understanding on how to avoid difficulties that come from natural inequalities, being kind.

Cities take a lot of resources but also hold a lot of people, they are place for many actions because of that. The chance is to have a high efficiency, the problem is logistics. Sustainability comes from resource-cycles, as i mentioned earlier. But the other, more social side is also important, the city or community has to be stable. This goes along with the prior goal of reduced inequalities. Because there are so many people affected by it, the design and state of a city is an important thing. 

One thing i want to mention is the resources that can be produced in a city, like some projects show on food or energy. These are good, because they avoid the logistics-problem, but may struggle on other parts.

"Take only what you need." We have to take into account what our actions cause on a greater scale, what sideeffects it has. This means we take the responsibility for our actions. We also have to look into the future, find the critical important resources and maybe preserve them or find another source. 

This is not only about the energy production but also the response to  effects that occur in our environment due to climate change.
I can name the melting of glaciers and pole ice, the desertification, fewer rain or water in rivers and ground, changing wildlife and also human habitats. Some things we can change for the better, some we can stop, on some we have to deal with the consequences. A lot has to do with water disappearing, CO2 and other gases in the air. The steps required also will use a lot of energy; desalination and CO2 filtering.
Climate change seems like a slow process but how fast are we in developing and implementing solutions on such a (worldwide) scale?! The changes are massive, require understanding, resources and effort.

Due to overfishing and climate change and all the waste thats thrown into the oceans, life below water is in danger. 

We have to find a solution which saves the underwater wildlife and lets us produce enough food. Fish and other seafood is a healthy food source. Moreover, the oceans hold precious resources which seem to be mined in the near future. 

Its a tough decision to make, how much we should change our environment. The impact should play a big role in the cost-use-calculation.

The impact on land is even greater than on water, we use a lot of space for living, producing food or other goods, industry and infrastructure.

A turning point could be the coexistence of humans and wildlife. We would build our cities in forrests or underground, or even out of living plants.

This lifestyle would require more work/energy and us dealing with fewer comfort than today. But we might find new synergies and a new quality or style of living, which may cover parts of the losses.A problem will be how to deal with the insects, rats, toxic or fast growing plants. Also bad weather and winter are difficult.

Safety is an important factor for everyday life. It strongly determines the decisions we make and is a highly emotional feedback for us. Also bad behaviour needs to be punished, else robbery and such would be done because its simple and successful. To fulfill the requirements for safety, you need a strong community with values or a  strong institution with enough resources. All other plans are difficult to follow if the environment is insecure.

To achieve all these goals we need knowledge and power, hours of work and great ideas. This collaboration is only possible if the right people come together and share one goal. We need a communication system, fixpoints which can coordinate and be addressed.
