Acquaintance
Today, humanity is facing a number of global challenges that threaten the sustainability of the planet and endanger the survival of the species inhabiting it. The world's growing population, climate change, scarcity of natural resources and environmental degradation are just some of the problems that we need to address urgently and effectively.
Global warming remains a problem of concern, with consequences affecting climate change, human health, and the occurrence of extreme events. According to the 2018 report of the Intergovernmental Panel on Climate Change (IPCC), global temperatures have increased by 1.3°C since 1880. In 90% of cases, the burden of anthropogenic warming is associated with greenhouse gas emissions (Recio, J, & Gay, J. 2019).
In recent decades, there has been a tendency to increase the content of suspended particles in the air due to environmental pollution as a result of transport and industrial activities. According to a 2018 WHO report, it is estimated that about 4 million people die prematurely from air pollution each year (WHO, 2018). According to a 2019 World Bank report, the concentration of CO2 in the atmosphere is approximately 410 ppm, which is 1.4% more than in 2018 (Recio, J, & Gay, J. 2019). However, despite the increase in atmospheric CO2 concentrations, historical records of low emissions have been achieved in some countries.
In this context, sustainable communities are presented as an innovative and encouraging alternative to address the greenhouse effect and build a more prosperous and equitable future for all. The scientific novelty lies in the proposal of a macro-idea based on five main axes, in which it will be necessary to apply the idea of Sustainable Communities of our generations, namely: population, economy, technology, food, environment.
Regarding the assessment of the current state of the issue, we can say that humanity has made significant progress in understanding global problems and implementing measures to solve them. However, much remains to be done, and even more actions will have to be taken to achieve an effective transition to a sustainable development model.
The goals and objectives of the implemented forecast are ambitious, but achievable. It is expected that sustainable communities will be able to adapt to ecosystem changes in which the environment will be severely compromised, and for this it is proposed to develop an economic model focused on agriculture and the evolution of agricultural systems, especially with a technological approach. In addition, it is expected that the classical family will become more relevant within these structures, in which the sphere of society will prevail, coexisting within sustainable communities. It can be predicted that such models will allow to exceed the clean air indicators by 30% in relation to global pollution.
SUSTAINABLE COMMUNITIES 2100
The next science fiction and innovative project "Sustainable Communities for Humanity in 2100" will be created in the context of the deterioration of the environment of society and nature, which is in the process of restoration. We will see a new world, and a new man - the one who lives on Earth in 2100.
The social structure, which is on the verge of bankruptcy on its various scales, will begin a new boom in changing habits, and the classic family will become more important within these structures. They will be dominated by the sphere of society that coexists within sustainable communities, offsetting indicators by 30% in relation to global pollution. A new lifestyle is beginning to manifest itself, which is quickly adapting to global structures.
The development of humanity will depend on its resilience, its ability to adapt and innovate, efficiency, cultural expression, equality and a sense of empathy born as adversity arises within the human collective. In the next work, the macro-idea will be considered along five main axes, along which it will be necessary to apply the idea of sustainable communities of our generations, namely: population, economy, technology, food, environment.
Within the framework of these five axes and the time factor in which sustainability is measured and the functionality of the model is determined, for their harmonious interaction, we will talk about the sustainable and integrated management of each of these points to create a Sustainable Community.
Sustainable Communities will be designed to be more resilient, efficient, stable, technological and technical in order to withstand natural challenges that will become increasingly repetitive and intense. These communities will be designed to meet challenges such as climate change, natural disasters and the emergence of new diseases. This will be achieved by creating a more sustainable infrastructure, diversifying the economy and creating strong social networks structured into a sustainable agricultural production system that ensures food security. Currently, three factors are distinguished within the framework of a sustainable structure: economic, social and environmental. In order to overcome the new challenges of humanity in 2100, the structure of sustainable development within Sustainable Communities will have the following goals: 
Figure 1.
 
Figure 1.

An interactive circular system of human sustainability in the year 2100. In the future, the Sustainable Communities of 2100 will become models of stability, adaptability and innovation. These communities will have the opportunity to adapt and survive the challenges caused by climate change and other adversities, demonstrating greater efficiency in the use of natural resources. In addition, they will focus on promoting equality and the general well-being of their members through a monetary system based on equal contribution and the involvement of all in industrial development.
Adaptability and the ability to innovate in these communities will be achieved through the introduction of sustainable agri-food technologies and systems, as well as economic diversification. In addition, it is important to have an effective communication system, free from the appearance of misleading information, to facilitate decision-making and cooperation among its members.
As for the economic model, it will focus on agriculture and the evolution of agricultural systems with a technological approach that will increase productivity and environmental sustainability. In addition, it will be based on the development of a resource allocation system that covers the basic needs of its members, ensuring a decent quality of life for all.
Sustainable Communities of 2100 will work on the basis of artificial intelligence and blockchain, which will provide a community management system and a system for monitoring and tracking the effectiveness of its existence. In this way, the communities of the future will be able to adapt and evolve in accordance with the changing needs of humanity, thereby achieving a more equitable, sustainable and desirable future for all. Other important characteristics of these communities include innovations in education, technology, healthcare, and communication between individuals and communities. The importance of these areas lies in the fact that the ability to adapt to changing global conditions and create new opportunities and solutions is crucial for the success of communities and, consequently, humanity as a whole.
To this end, online communities facilitate knowledge sharing, project collaboration, and the development of new skills. In addition, the introduction of innovative practices in education, health and communication can help these communities improve the quality of life of their members and reduce the qualitative gap between residents of rural and urban communities.
Networked communities also seek to strengthen the bonds between communities and instill a sense of belonging to a unified system through activities that promote collaboration, interaction and active participation of individuals. This can be the organization of cultural, sports, educational events, as well as the implementation of volunteering and mutual assistance programs among people belonging to the community.
These communities can also work to improve access to basic services and resources such as clean water, electricity, health and education. To achieve this goal, they can collaborate with government agencies, non-governmental organizations and other relevant actors in the development of infrastructure projects and public services.
In 80 years, technology can be used to create a fair system of non-monetary distribution of basic services necessary to improve the quality of life in society. This will be achieved through the introduction of a decentralized blockchain platform, joint human resource management systems, virtual communication and collaboration systems, intelligent devices and tools for monitoring and tracking the effectiveness of the community, as well as a community management system based on artificial intelligence and blockchain.
The resource allocation system will be implemented and focused on all those basic needs that mainly depend on technology and their development, because the more information about achievements and developments in the community can be quantified, the higher the system offers a quality of life for all its people, not forgetting those who can be represented as the most vulnerable are due to their age or a condition that prevents active participation in the community system.

Today's cities are nothing more than a jumble of houses with problems of overcrowding, lack of hygiene, lack of resources, and high levels of insecurity. In a very unfair and disproportionate system of large cities, the concept of community and society has long been forgotten due to the fact that there are more individualists in it than parts of the collective. For this reason, there will be retro-migration to rural areas where sustainable communities can be adapted to healthy coexistence of the individual.
Generation 2100 will continue to face the problem of lack of forest plantations, but will cope with it with the help of genetic markers and enhancers in each tree species so that they better adapt and recover from destroyed ecosystems.
In the course of technological development, there will come a time when a certain part of society will have to move away from it for the sake of its mental well-being and healthy coexistence, there will be a rejection of property and the rejection of future social networks, which can create obstacles for the future human generation.
The environmental problem will reach a different level, its solution will be a new boom, when we will strive to correct the environmental atrocities committed by our generation through the abuse of natural resources. These new technologies and efforts will focus on cooling our planet based on panels that will capture overly active and harmful solar rays and convert them into necessary energy. Scientists will continue to work on genetic improvement so that agriculture can guarantee food production, while not depending on destructive natural phenomena, which by that time will occur much more often.
From an ecological point of view, due to the devastating effects of pollution, the ecosystem will become poorer, but for the most part these sustainable communities will be responsible for preserving the environment in order to maintain a quality of life in harmony with the environment.
In agricultural concepts and agricultural management, sustainable agriculture has the tools to change the nutritional level of its crops or their derivatives over time. Caring for the soil and respecting the microbiota that exists in it will create and revive healthy soils that will bring to life a functional edaphic ecosystem for the introduction of nutrients into the plant that is in it, or the animal that feeds on this plant. Sustainable agriculture uses a variety of factors that ensure environmentally friendly, socially equitable and economically beneficial conditions over time.
Population
Man was created to live in society, and the power of this will contribute to building a shared future that depends on both personal and group development in conditions of freedom of thought. Focusing on innovation and divergent thinking will ensure the development of humanity and adaptation to future challenges. The importance of personal freedom and free-thinking, along with the strength of the family structure, will be crucial to the success of future generations.
Despite the challenges ahead, technological progress and humanitarian critical thinking contribute to building the future together. A society based on cooperation and the free expression of ideas will contribute to the well-being and survival of humanity in the 21st century. Population growth rates will undergo significant changes during the 21st century, although birth control will ensure a balanced population. In addition, the introduction of advanced contraceptive technologies will facilitate birth control in a conscious and voluntary environment. According to the United Nations, the world's population is expected to reach 8.5 billion by 2030, 9.7 billion by 2050, and 10.4 billion by 2100.
Despite the fact that the world's population will strive to grow, birth control and advanced family planning technologies may lead to a decrease in the world's population in the coming years. By 2100, we will be able to better control the procreation of people on our planet.
At the same time, environmental issues such as climate change and loss of biodiversity will lead to a reassessment of cultural practices and the creation of new strategies and technologies to mitigate and adapt to these changes. Technology and artificial intelligence can also be used to preserve and transfer cultural and ancestral knowledge.
However, the year 2100 will face ethical and social issues such as the control of technology over decision-making and the balance between individual autonomy and responsibility within a social structure. To solve these problems, it is necessary to promote dialogue and cooperation between different cultures and societies, as well as invest in ethical and humanitarian education for future generations.
Food
Human food in 2100 should meet the needs of the population without compromising natural resources for future generations. This means that food production must be environmentally friendly, socially equitable and economically profitable. Sustainable agricultural practices should be used to promote the introduction of nutritious and resilient species in food production. These are organic farming, circular farming, community farming and the diversification of crops resistant to adverse conditions. Employees should be paid fair wages.
The distribution of food in 2100 should be fair and equitable in terms of basic needs, low yields and individual indicators between collectives. It is necessary to use the technological ecosystem to identify the needs of each individual in the team and, thus, meet them in the most personalized way. It should be thought out to encourage residents, having reached a certain age, in the presence of physical disabilities and peculiarities, to guarantee themselves constant access, like all members of the community, to adequate and nutritious food. This is always due to the fact that food distribution should be based on solidarity and cooperation, and not on profit, which is considered a basic need of society. By creating sustainable communities and local food sources, we significantly reduce emissions from food chains during their transportation.
The variety of crops that will be planted will help preserve genetic variability and a wide range of products in the community's food system. Laboratories will conduct research on seeds or plant tissues to develop more nutritious plant material within a sustainable system that respects the ethics and morality of nature with minimal interference with the ecosystem.
By 2100, food sovereignty will become a reality for many communities around the world. These communities will be able to develop sustainable food systems that provide nutritious and healthy food for all their members. With the help of technological advances in medicine, the personalization of basic nutrition can be realized and satisfied in a very rational way for each person, knowing what nutrients they need and knowing with which locally produced products they can meet this need.
The focus will be on preserving the culinary traditions and culinary diversity of various communities. This can be facilitated by policies that promote the production, self-sufficiency and consumption of local and traditional foods.

Environment
Shepherd et al. (2018) present a conceptual model of climate engineering that explores the interaction between aerosols, suspended dust and infrared solar radiation in the troposphere. Aerosols play a crucial role in altering albedo and scattering sunlight, while microorganisms in suspended dust can affect the production and release of secondary particles. In addition, research in this area focuses on assessing the impact of various climate engineering technologies on climate stability and change.
Wood Wide Web was first discovered in the 1990s by Canadian mycologist Suzanne Simard. This is the so-called "global forest network". Simard and his colleagues were studying how trees compete with each other for resources when they discovered that trees are actually connected to each other by a network of fungi. This network allowed the trees to share nutrients and water, fend off pests and diseases.
Microorganisms such as bacteria and fungi play a crucial role in soil health and nutrient availability for plants (Beltrán Pineda, M.et al. 2017). Technological development will take place not only in robotic equipment or tools, but also in the search for improved living organisms that we already have, and new varieties of them that will evolve to adapt to new environmental conditions that will arise in a more polluted atmosphere and fight toxins. One of the biggest challenges will be to help flora and fauna adapt to the changes so that they don't disappear.

Bioremediation is a process that uses living organisms such as bacteria, fungi, and plants to decompose or transform pollutants in the environment, convert them into less toxic forms, or eliminate them completely. This is a promising method for cleaning agricultural soils contaminated with organic pollutants such as hydrocarbons and polycyclic aromatic compounds (PAHs) (Kisic, I. et al. 2022).
The technology will help to use the genetic improvement of microorganisms so that they promote the development of beneficial microorganisms in the soil, helping to restore large areas of worn-out soils that humanity will inherit by 2100. Technological tools will appear, such as "super-microorganisms" with genetic enhancers (enhancers of certain properties), which will help to carry out edaphic bioremediation for the productive use of these inefficient lands.
 
Figure 2 : Productive agricultural projects in the year 2100, developed with the help of AI.
These microorganisms will help ensure biodegradation during development and
a productive cycle for plant adaptation, accompanied by intelligent fertilization. "Nanobiobertilizers" determine the needs of crops and release nutrients for their proper growth in accordance with the phenological curve. The same nanobiobertilizers will be based on derivatives of microorganisms and plant organisms. The technological development of bioparticles and the satellite network will be interconnected in order to receive information from the field in real time. The Forest Internet is an innovative concept that can turn into an advanced science by the year 2100. This revolutionary concept is aimed at solving the problem of exponential urban growth and degradation of natural ecosystems.
I imagine a reality in which it will be possible to design and build cities in forests connected to each other by a complex wireless network. This Internet system, dubbed the Internet of Forests, will be based on the introduction of advanced technologies that will allow the creation of cybernetic infrastructures that are invisible and almost indistinguishable from the environment.
An example of how this wireless network can work is a combination of satellites and nanoscale bosons. These satellites, orbiting at much higher altitudes, can maintain constant communication between human devices and network nodes. On the other hand, nanoscale bosons will be responsible for transferring information between devices and nodes in the network in a completely decentralized way and without the need for a fixed infrastructure.
In this futuristic scenario, cities in forests will not only preserve the biodiversity and beauty of natural ecosystems, but also connect forests via the Internet to share knowledge, resources and opportunities. This would allow local communities not only to thrive economically, but also to take care of the sustainability of the environment and the conservation of species and ecosystems. Finally, it should be noted that such a scientific and technical approach aimed at preserving nature and the well-being of local communities will not only be beneficial for the environment and future generations, but can also contribute to the development of new and sustainable forms of urban life. In short, the Internet of Forests represents an exciting and innovative promise of a future in which humanity learns to live in harmony with nature and with the planet itself.
Governments will implement policies aimed at encouraging the production of environmentally friendly food, for example, encouraging and investing in organic farming.

Technologies
By 2100, science will be a pillar of the social and geopolitical structure, as it will provide a complex of multifaceted conditions for social well-being, the development of science and technology.
A breakthrough is expected in the healthcare system. When patients complain, they must be checked on high-precision diagnostic equipment and promptly delegated to a specialist doctor with the diagnosis and treatment of the diseases they suffer from. In this way, the fatigue burden of medical professionals is reduced, and they can function better with the support of technology. The development of outpatient polyclinic centers with medical tele-guidance and supervision by several specialists will make it possible to make interventions for medical complications available to anyone.
By 2100, genetic diseases can be easily cured using advanced genetic engineering techniques. For example, an artificial virus can replace harmful mutations in the patient's genome with appropriate DNA sequences, thereby restoring the function of the defective gene.
Artificial intelligence will be distributed throughout the human body. For example, nanomicrochips implanted in the brain will provide a direct link between the mind and technology. This makes it easier to access instant information, communication and learning at any time, constantly updating the human mind.
Nanomolecular technology using bosons can be applied in great progress in the system of interrelations between the environment and human society, allowing the exchange of information about various biological variables that converge in our system in real time. With increased communication capabilities, we will be able to better socialize decision-making with all stakeholders.
Optical connections in nanotechnology are an area of active research because they enable faster and more efficient data transfer compared to traditional electronics-based technologies. Photons, like bosons, do not interact with each other, which makes it possible to transmit a signal without loss and interference. In this context, nanometer-scale optical waveguides can be used to transfer data between various nanoelectronic components. These components can be devices such as transistors or sensors that will be interconnected using optical channels for fast and efficient communication (Paul, A., & Valli, M. 2022).
Bosons can also be used in nanotechnology to manipulate and control particles at the nanometer level. For example, they can be used to capture and move nanometer-sized particles using optical tweezers, which allows precise manipulation of materials and structures at the nanometer scale. Research in this area is continuing, and it is expected that new interesting discoveries will appear in the future.
Quantum technologies can revolutionize medicine, allowing for more accurate diagnoses and more effective treatments. For example, quantum computing can help analyze large amounts of genetic data to identify patterns and develop personalized treatments. In addition, quantum sensing can improve the accuracy of early detection of diseases.
The combination of artificial intelligence and quantum technologies can lead to significant progress in the field of AI. Quantum computers will accelerate the learning of AI models and improve the computing power of large amounts of data. This can find applications in areas such as pattern recognition, machine translation and autonomous decision-making to improve productivity in various industries (Auffeves, A. 2022).
Quantum technologies can also have an impact on the energy sector. For example, quantum computing can help optimize energy production and distribution, while quantum sensing will increase the efficiency of renewable energy collection and storage.
Cooperation between countries to solve global technological, energy and food problems can become an important feature of international politics. International agreements will be able to establish common standards for food and technological sustainability, as well as equitable resource allocation.
A government commission could be set up to oversee and regulate the behavior of technology corporations. This commission could establish strict rules to ensure that corporations do not violate human rights or ethical standards in their activities. With the introduction of new data monitoring and storage technologies, it is crucial to ensure that existing laws adequately protect citizens' privacy rights.
Economy
The economic system and model will be based on the productivity of sustainable communities, large industries and supply chains. Since they will guarantee food security, they will also be able to contribute to those areas that relate to other aspects of human activity. The economic structure and model will be based on population growth in a sustainable environment. In Western philosophy, the philosopher Thomas Hobbes developed a theory in the seventeenth century about how people interact in society. The theory is known as the "social contract" (Castaño D, 2011). In this treaty, people agree to delegate some of their sovereignty to the central government in exchange for protection and stability. According to Hobbes, this agreement allows people to coexist peacefully, which translates into the form of a "contract" or agreement between them. However, this theory also suggests that if people are unhappy with the government's actions, they have the right to cancel the contract and organize a new government. This idea, in turn, is a defense of liberalism and the right of individuals to free association and separation, which is transformed into a defense of individuality and freedom in society. In order to adapt to these ecosystem changes, in which the environment will be severely compromised, it is necessary to develop an economic model focused on agriculture and the evolution of agricultural systems, especially with a technological approach.
Consequently, research and development of new technologies and approaches to improve agricultural productivity and sustainability will be encouraged. This will include the use of robotics, sensors, nanotechnology, nanobiobacteria, intelligent satellites with pre-action command systems and information systems to monitor and optimize agricultural practices, genetic improvement and genetic re-equipment of organisms to adapt plant matter to an ecosystem altered by climate impacts.
The relevance of the community economy (Guzmán, M. et al. 2023) lies in the ability to support economic development, environmental conservation and social integration. Encouraging the active participation of community members in economic decision-making and resource management strengthens the community's identity and creates a sense of belonging. In addition, the community economy contributes to the efficient use of resources by minimizing waste generation and reducing environmental impacts (Beltrán Pineda, et al. 2017).
Combining ancestral knowledge, traditional practices, scientific knowledge and closed-loop economics strategies, it is possible to develop innovative and sustainable solutions to today's problems. The community economy also promotes equality and social justice by prioritizing collective well-being over individual benefit.
By 2100, the EU economy will undergo changes due to economic factors. The incomes of sustainable communities can be higher due to the introduction of efficient technologies and resource optimization. This could lead to greater availability of resources to finance community projects and promote the economic well-being of their members.
Environmental impacts will also play a role in the evolution of the community's economy. For example, the promotion of sustainable farming practices and the introduction of recycling and renewable energy technologies can reduce the carbon footprint. This can lead to tax breaks and environmental regulations that will support sustainable economic growth in communities.
Technological innovations will play a key role in the evolution of the economy of a Sustainable Community. For example, advanced information and communication technologies will facilitate collaboration between sustainable communities and disseminate useful information about successful economic and environmental practices.
Conclusion
Population: The introduction of sustainable communities can help solve the problem of population growth and reduce the pressure it exerts on natural resources. In order to achieve a sustainable level of population, family planning and education must be promoted.
Economics: Agriculture and the evolution of agricultural systems are fundamental to the development of sustainable communities. Technological innovation and investment in infrastructure must be encouraged to achieve a sustainable and equitable economy.
Technology: Technology is a key tool for the development of sustainable communities. Research and development of environmentally friendly and efficient technologies should be encouraged to achieve a more sustainable society.
Food: Food is a fundamental aspect for the development of sustainable communities. To build a healthier society, it is necessary to promote sustainable agriculture and the production of healthy and nutritious food.
Environment: Environmental protection is a fundamental aspect for the development of sustainable communities. It is necessary to promote the conservation of natural ecosystems and the introduction of sustainable practices to achieve a cleaner world.
The implementation of the concept of "Sustainable Communities" is presented as an innovative and encouraging alternative to solving global problems that threaten the sustainability of the planet and the survival of the species inhabiting it. In this document, we have examined the various aspects that make up this proposal, from the population to the environment, including economics, technology and food.
