Category: Other Natural Resources

Apart from water and energy resources (given in separate “Categories”) there are many other types of essential resources of natural origin, e.g. land, peat-lands, forests, mineral deposits, wildlife and biological flora and fauna, geological formation both on earth’s surface and the beneath. Major parts of these resources form our natural global biodiversity and needs protection measures through both formal and non-formal instruments.

New Addition – Editorial: Professor Anders Wörman. ‘KTH’ Royal Institute of Technology, Stockholm.

Professor Anders Wörman is the Head of division for Resources, Energy and Infrastructure, The Royal Institute of Technology, Stockholm (https://www.kth.se/profile/worman).

His research interest spans over wide-range of trans-disciplinary and trans-sectorial areas in engineering sciences and technology within water resources, hydrology and environmental hydraulics. Ongoing research are due to water and energy availability in terrestrial hydrology, effects of climate fluctuations and landscape changes on runoff, hydropower regulation, extreme flows in rivers and safety of embankment dams. His skill and expertise include: environmental impact assessment; water quality; water resources management; engineering, applied and computational mathematics; hydrological modeling; rivers; civil engineering, hydrologic and water resource modelling and simulation; water balance; waterfall runoff modelling; aquatic eco-systems; surface water geo-statistics; contaminant transport; groundwater penetration; radar and climate change impacts.

Professor Wörman was co-founder and the first manager of the undergraduate educational programme for Environmental and Aquatic Engineering at Uppsala Univ. before being chair prof. at KTH. KTH has dedicated research programmes in Applied Sustainability. One of such programmes is oriented towards finding customized solutions to develope sustainable and resilient technical applications that are climatically and environmentally suited for Africa (https://www.kth.se/en/om/internationellt/projekt/kth-in-africa/africa-1.619441). It is interesting to mention that the world longest river, the Nile, spans over large catchment areas that are located in different climatic/weather (spatio-temporal variability in temperature and precipitation) zones (http://atlas.nilebasin.org/treatise/nile-basin-climate-zones/). These special features of the Nile call for technologies that can cope with climate-environment changes of both natural and man-made origins. Combination of natural and man-made climate changes will certainly induce severe constraints and limitations on what, why and how ‘Water, Energy and Natural Resources (fossil and mineral deposits, eco-systems and biodiversity)’ Nexus need to be carefully accessed on long-term and large-scale bases. In this context, Prof. Wörman has trans-disciplinary and trans-sectorial knowledge suited to handle the complex, inextricable and multi-layered interactions within and between Water, Energy and Natural Resource Systems. These interactions are imperative to understand of coherent and resilient coupling with the Socio-Economic-Environment ‘SEE’ aspects in communities living in river-catchment systems in Africa. These issues are of special interest as river-systems are the dominant landscape units with huge importance for preservation and protection of renewable and fossil resources.

Nanotechnology inventions of the Ancient Civilisations

Historical texts from Spain, Italy, the Middle East and Egypt revealed how lustreware, pottery, batteries, steel swords and hair-dyeing were using nano-composites generating metal-glass and metal coatings on surfaces in different ways to produce impressive products of exceptional quality with enhanced material’s properties (https://www.theguardian.com/nanotechnology-world/nanotechnology-is-ancient-history). Damascus steel swords from the Middle East were made between AD300 and AD1700 with impressive strength, shatter resistance and exceptionally sharp cutting edge. The blades contained oriented nanoscale wire-and-tube-like structures with exceptional qualities. Pottery across the Renaissance Mediterranean was often decorated with an iridescent metallic glaze of colour and sheen down to nanoparticles of copper or silver.
Ancient Egyptian hair-dyeing, dating to the Graeco-Roman period, was shown to contain lead-sulphide nanocrystals of 5 nanometre diameter (https://neurophilosophy.wordpress.com/2006/09/06/the-ancient-egyptians-used-nanocosmetics/).

Though craftsmen were highly skilled to produce such materials that by modern definitions falls under nanotechnology they didn’t not know that they were working on the nanoscale. Such amazing inventions from ancient times dated back to thousands of years are numerous examples of ancient technology that leave us awe-struck at the knowledge and wisdom by the people of our past. They were the result of incredible advances in engineering and innovation as new, powerful civilizations emerged and came to dominate the ancient world. Many of such ancient inventions were forgotten, lost to the pages of history, only to be re-invented millennia later. Among the best examples of ancient technology and inventions are: 2000-years-old metal coatings superior to today’s standard; 2000-years-old Bagdad battery; 1600-year-old Roman artisans of impregnated glass with particles of silver and gold; the Assyrian Nimrud lend of the oldest telescope; the steam engine by the Hero of Alexandria and many more (https://www.ancient-origins.net/ancient-technology/ten-amazing-inventions-ancient-times-001539).

Prosperity – Africa in the 21st Century

In a series of posts we will explore why the 21st century will be prosperous for Africa. Indeed, there are various reasons to predict why Africa will continue to shine more and more though the threats that climate change, including global warming, will hit Africa more than other continents (https://en.m.wikipedia.org/wiki/Climate_change_in_Africa). Naturally there are other threats that so far hindered Africa from faster developments as compared to the rest of the world, specially that the history of Africa is very much different. Here is a list of key factors, among others, about the ongoing tectonic changes and drivers that will bring a lot of positive socio-economic impacts in Africa.

– African identity, slavery and colonialism distorted her identity and disoriented her values. However, Africa was not the only continent that suffered colonization. The concept of African identity has changed are still changing relatively fast specially with the growing restrictions in migration.

– African independence, decolonization and transition to independence characterized the past century and national identities in many parts of Africa are gradually emerging.

– Large-scale infra-structures, there are mega projects taking place in Africa (the case of Egypt participation in partnership for goals, Goal 17 of UN-SDGs) such as developing its transport systems to connect the continent from the very north in e.g. Egypt to its very south, South Africa, also from the west to the east (https://www.egypttoday.com/Article/1/77914/Egypt-launches-32-projects-in-Africa-in-1-year-report). One example is the enormous use of smart phones technology in trade, business and finance.

– Coupling rural to urban regions, this among key and important issues in the development of Africa as 70% of African are living in rural Africa and producing 70-80% of agricultural outputs.,

– African Union, AU is a continental body of the 55 member states that make up the African Continent. It was officially launched in 2002 as a successor to the Organisation of African Unity (OAU, 1963-1999).

– Human resources, population growth and youth, towards 2100 the population of Africa will peak to about 40% of the world population with very high percentage of youth.

– Natural resources Africa is abundant with natural resources including diamonds. gold, oil, natural gas, uranium, copper, platinum, cobalt, iron, bauxite and cocoa beans. This is of course in addition to its amazing biodiversity.

– Generation shift, new generations and leaders are currently shaping and reshaping Africa, combating corruption, enhance good governance and transparency and taking advantage of modern technologies, e.g. ICT, IOT, crowdfunding, protection of natural resources, also in the energy, agriculture, farming, tourism and other sectors.

– Security, many African countries are becoming more aware about the improvement of national integrity and internal security and safety of population specially that Africa has a complex diversity of ethnic groups. Remarkable developments in safety in Africa took place and still the focus of the African countries.

– Biggest market in the world, the needs of Africa will make it one of the biggest market in the 21st century. There is diversification and expansion the economy and trade both internally and with the rest of the world including Europe and Asia. This will generate tectonic changes in international trade, business, transport and mobility in labor and services.

– Global investments. Based on data through 2017, France is the largest investor in Africa, although its stock of investment has remained largely unchanged since 2013, followed by the Netherlands, the United States, the United Kingdom and China. Geographically Europe and Asia can be linked through North Africa and the GCC countries.

– UN-SDGs the world has created a global agenda for promoting and implementing sustainability which Africa will benefit considerably from it. UN-SDGs and involved targets for developments are key issues that are shaping policies and strategies to cope with poverty, hunger, gender, inequalities, education quality, health, water and sanitation, energy, strong institutions, life quality, biodiversity, ……. etc.

THE DESIRE TO TEACH their children about computers drew these Samburu women to a classroom in a settlement north of Nairobi. They are learning about tablets—designed to withstand tough use—that connect to the Internet through a satellite and come preloaded with educational programs. Technology now has arrived in isolated regions of Africa primarily in the form of relatively inexpensive cell phones.

Full Documentary of the Nile’s Social Life by Joanna Lumley

Though many journeys and expeditions were done to discover the secrets of the Nile, very few of them, if any at all, touched upon the diversity of life, traditions and cultures of the Nile people. The Nile people have deep rooted love and worship for the Nile and its waters for thousand of years. The Nile and its waters meant, still mean and will continue to do so for generations. The life of the Nile people is as complex as evolution and history of the Nile itself. In this context, the socio-economic performance of the people of the Nile is very central and crucial for finding sustainable and peaceful ways to share such magnificent gift of nature. These indeed, are parts of wicked conflicts of how to put such enormous diversity in political agreements for lasting harmony in the Nile Basin as a whole. This is also the case of the rest of Africa as rivers and their catchments are basic landscape units of existential importance for the livelihood of the African population. However, vast regions of Africa don’t enjoy surface water resource or rain and other alternatives are imperative such as groundwater, desalination and water reuse. In most cases we need to think in 3D-solutions that couple surface water with groundwater and also to understand the long-term consequences of water production, use and consumption on the landscape level on longterm and large-scale levels. This can be simple to say if such resources were infinite, however water scarcity in Africa is the highest in the world yet major threats are emerging due to climate change, growing population, increasing diversification in economy, acceleration of urbanisation and industrial activities with all consequences of growing waste and pollution. The search for how such transboundary solutions of the water resources to be shared is a major political issue. All of this come in the time of today’s very rapid and fast growing ’diversification’ of the socio-economic-environment conditions needed for the ongoing transformation to sustainable societies.

Joanna Lumley’s journey, in search for the very source of the Nile, by being the longest river in the world, comes with very interesting introduction on the cultural diversity of the life and livelihood of the population in the Nile Basin. Among the amazing issues is the longstanding socio-economic diversity that shaped the life in the Nile Basin for thousands of years ranging from e.g. evolution of tourism; preparation for marriage; social gathering and social therapy ‘Soffi’; beauty treatment ‘Dukhan دخان’ (form of SPA) of body, skin and smell; sports in rural areas; local food and drinks; coutry-side work and services. Traveling, for example, comes with major challenges because of the unique landscape in the African canyons, river-catchment and forests. Respect and appreciation of cultures is the secret of not only social success but more importantly to bring about harmony and resilience in the complex social mosaic that requires modern understanding of ‘what, how and why’ issues in modern sustainability.

Just to give few examples is how to live and travel in one of Africa’s largest canyons of the Blue Nile, 250 miles long. Also, how to manage the 60 rivers that drain rainwater to Lake Tana in Ethiopia. The country with 4/5 of the african mountains and Africa’s oldest cultures that is most diverse with great influences from ancient Egypt and Arabia.

One of the great future challenge of the 21st century is how to deal with the growing scarcity of Africa’s white gold ‘water’ (https://en.m.wikipedia.org/wiki/Water_scarcity_in_Africa As of 2006). One third of all African nations suffers from clean water scarcity and Sub-Saharan Africa has the largest number of water-stressed countries of any other place on the planet. It is estimated that by 2030 that 75 million to 250 million people in Africa will be living in areas of high water stress, which will likely displace anywhere between 24 million and 700 million people as conditions become increasingly unlivable.

HR-Group for UN-SDGs in Africa – Prof. Amidu O. Mustapha.

Sustain-Earth.Com will work on mobilizing Human Resources in Africa for empowering the youth and students for scaling up Science, Technology and Innovation ‘STI’ to promote the UN-SDGs. We are delighted to have Professor Amidu Olalekan Mustapha from University of Agriculture, Abeokuta, Nigeria to work on these issues.

Furthermore, the necessary instruments and tools will be developed and implemented for active engagement of the higher education, universities and research institutions in Africa to couple ‘STI’ to society, population and market needs. University graduates, early-stage researchers and professionals (according to scientific and technical merits) through dedicated mentoring programmes will act as catalysts in creating the necessary multi-layered links with relevant stakeholders in all sectors and on all levels. The diverse, rich and wide-range of higher education and research programmes in Africa will provide the necessary Human Resources ‘HR’. This will involve raising the public awareness among the involved stakeholders. A data-base will be created to define, collect and compile the expertise, professional and the targeted stakeholders.

The involvement of high-level interactions with sectors and organisations as was the case in previous trans-disciplinary and trans-sectorial activities, e.g. IRPA-Nairobi Conference in 2010 (http://www.iur-uir.org/en/archives/conferences/id-44-afrirpa2010-third-african-irpa-regional-congress) will be assessed. This will be part of building on previous experiences and successes of already existing networking infra-structures. However, this will still require major challenges but suitable grounds will be found for what and how to do. According to Professor Amidu Mustapha there are a number of existing initiatives and platforms that we can link up with, e.g. both in Nigeria and Kenya. The members of the existing groups may also have other goals in addition, but we can benefit mutually in the common areas of environmental sustainability and knowledge development especially among youths.

A starting point will also involve reshaping and tuning two previously given courses at Uppsala university in 2018 and 2019 (http://teknat.uu.se/digitalAssets/395/c_395062-l_3-k_sustainability-in-science-and-technology.pdf; http://www.teknat.uu.se/digitalAssets/395/c_395062-l_1-k_sustainability-in-science-and-technology-2019.pdf). In these two course water, energy and natural resources nexus were detailed in order to explore what, why and how these drivers can be coupled to socio-economic-environment aspects that are necessary to help the ongoing transformation to sustainable societies. Over twenty professors and professionals were involved in conducting these courses, however there are still enormous needs to develop and extend these courses to meet the realities in many developing countries specially in Africa. This is also while considering the practical approaches that would be required in the implementation process. Particularly what regards the existing and emerging needs (UN-SDGs) in Africa for practical and appropriate policies and strategies.

ESG Sustainability Factors – Godfrey Mchunguzi Oyema

Sustain-Earth.Com is introducing an ESG (https://en.m.wikipedia.org/wiki/Environmental,_social_and_corporate_governance) Fund-Raising team where Mr. Godfrey Mchunguzi Oyema, Tanzania, is excellent addition to sustain-earth.com. Mr. Godfrey Mchunguzi Oyema is a passionate and results-driven Environmentalist, Biodiversity (Wildlife) and Human Ecologist, ESG policy professional with understanding of the challenges facing biodiversity both in-situ and ex-situ conservation. His work involves analytical approaches to using observation strategies to predict and monitor behavior changes of animals in captivity and natural habitats. He has diverse and rich knowledge of managing animals in captivity using a variety of methods, as well as camera traps and behavior monitoring. His expertise is based on smooth business operations by collaborating with project partners and following projects from conceptualizing phase to completion including theory of change design, incorporation of partner needs and technical support.

Environmental, Social and Governance (ESG) are three central factors in measuring sustainability dimensions and the societal impact of investments in companies. The social and environmental responsibility affects financial and economic performance in private and public sectors. The social capital is an important factor in establishing strong human capital and so is the case of the underlying environmental conditions of social frameworks. These are important in encouraging companies and capital markets to incorporate environmental and social challenges into their day-to-day decision-making.

ESG had also received most of the public and media attention, not least because of the growing fears concerning climate change which directed the spotlight more and more onto the corporate governance aspect of responsible investment. It brought also the focus to how the companies were managed, what the stockholder relationships were and how the employees were treated. The evidence toward a relationship between ESG issues and financial performance is becoming greater with wider recognition of the necessity of the sustainability in long-term investments. The environmental social and corporate governance are becoming increasingly important in the investment markets https://www.investopedia.com/terms/e/environmental-social-and-governance-esg-criteria.asp).

Public goods are natural resource enjoyed by every person and it is impossible to prevent someone, including living organisms, consuming such good, e.g. air for breathing, water for drinking, sun and light to enjoy. Public goods are recognized as beneficial for everyone and therefore have existential values and necessities that must not be destroyed by one person or state. In this context, natural resources and the environment are global public goods that are should not be diminished, exhausted and/or degraded, e.g. a breathable atmosphere, stable climate and biodiversity. For these reasons Environmental Governance (https://en.m.wikipedia.org/wiki/Environmental_governance) is also a political ecology and environmental policy concepts that advocates sustainability for management of all human activities. Governance includes government, business and civil society.

Sustain-Earth.Com will expand on ESG and its growing importance for promoting and achieving the UN-SDGs (https://www.un.org/development/desa/disabilities/envision2030.html).

Africa’s Future Gold Mine – Renewable Energy Future Opportunities and Needs

Africa has enormous untapped resources of renewable energy resources such as solar, wind, geothermal, bio-energy and hydro-power (https://www.renewablesinafrica.com).

Africa has the highest incidence of food insecurity and poverty and the highest rates of population growth. Yet Africa also has the most arable land, the lowest crop yields, and by far the most plentiful land resources relative to energy demand. It is thus of interest to examine the potential of expanded modern production of renewable in Africa. Renewables in Africa are future strong enablers and drivers for sustainable developments with enormous socio-economic-environment benefits. Renewables in Africa will help to achieve its vision for Green Growth (https://www.greengrowthknowledge.org/sites/default/files/downloads/resource/African%20Development%20Report%202012_4.pdf). In Brazil, for example, bioenergy development have been synergistic rather than antagonistic. Realizing similar success in African countries will require clear vision, good governance, and adaptation of technologies, knowledge, and business models to myriad local circumstances. Strategies for integrated production of food crops, livestock, and renewables, e.g. bioenergy are potentially attractive and offer an alternative to an agricultural model featuring specialized land use (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4337098/). If done thoughtfully, there is considerable evidence that food security and economic development in Africa can be addressed more effectively with modern bioenergy than without it. However, what regards bioenergy which is so far a major resource of energy in Africa, researchers warn about its negative climate impacts and a brake on bioenergy by 2050 is suggested. This will alleviate the extreme pressures on land in the coming 30 years and avoid the negative impacts from high carbon footprint and excessive land use biomass production from crops, trees or grasses for fuel through 2100 (https://www.google.se/amp/s/phys.org/news/2019-12-bioenergy-negative-climate-impacts.amp).

Here we illustrate an excellent example of renewables from one of the African pioneers in Geothermal power generation in East Africa and the Rift Valley (https://geology.com/articles/east-africa-rift.shtml). The geology, evolution and landscape of the Rift Valley (https://geology.com/articles/east-africa-rift.shtml) in Africa makes it a unique resource and an example of the untapped renewable energy resources. Working opportunities in the energy market in Africa would open huge employment possibilities for technical engineers, including ICT.

DM and CEO of KenGen Rebecca Miano, Kenya, gives us a glimpse on the future of Renewables in Africa (https://m.youtube.com/watch?v=XOreOpeqQ4o&feature=youtu.be). KenGen as a global pioneer in geothermal energy in Africa and the world, it has access also to affordable inhouse expertise to meet crises such as COVID-19. However, demand in energy for expansion and modernization of power plants are enormous and would need more and more technical skills.

Africa’s Sustainability – Hydro-Power and Energy-Water-Food Nexus

Why do we need Energy? Why do we need Water? Why do we need Food? and How these three basic needs are related to the Earth’s Natural Capital Resources. For Africa where its population will peak to reach about 40% of the world population by the end of this century including housing the youngest population on planet Earth, it is IMPERATIVE to know how this wicked “Water-Energy-Food-Natural Resources” Nexus will be managed. With the huge and growing global pressure on Africa’s mineral/natural resources and with the other given needs in mind, how can we define Africa’s Livelihood on the bases of achieving the UN-SDGs?

The new dams in Africa have the potential to meet increased energy (electricity) demands. At the same time, there are strong coupling between climate and the “water, energy and food” in Africa. Also strong links with the global needs for Africa’s natural resources. On the large-scale and long-terms spatio-temporal changes, locations of the planned dams could put the security of electricity supply at risk for large parts of Africa. As the majority of planned dams are located in river basins with upstream and downstream regions that rely on similar patterns of rainfall and hence be vulnerable all together to drought and dry years. Also, subject to other extreme climate and weather threats caused by major changes in rainfall pattern such as uncontrolled flooding. These vulnerabilities could lead to electricity supply being disrupted. This is why it’s important to factor climate variability and change into dam design and management, and diversify the electricity production, to avoid over reliance on hydropower.

Hydropower relies on the flow of water to drive turbines for electricity generation. It uses natural changes in elevation or artificial storage in reservoirs to take advantage of the water level difference. Drought or successive dry years can result in not having enough water to drive the generating turbines and thus cause shortage of electricity. In countries like the US and in parts of western Europe hydropower is complimented by other power sources. This means that in times of drought other sources of power can balance the shortfall. But in countries where the energy mix is or will be dominated by hydropower as in e.g. Africa specially the sub-Saharan African countries. Without alternative power sources, the impacts of climate can cause fluctuations in hydropower and thus can disrupt electricity supply. Supply might need to be turned off either to ration dwindling water resources or because demand simply can’t be met. For example, the Nile and Zambezi, where multiple dams are planned on the same river channels and lie in the same rainfall clusters. This means that dry years will affect storage in all the dams, lessen their ability to refill fully and could create a significant challenge for the supply of hydropower. There are already examples of this happening (http://theconversation.com/new-dams-in-africa-could-add-risk-to-power-supplies-down-the-line-89789). In December 2017, for example, Malawi’s state owned electricity company saw power output plummeting after a severe drought. Malawi relies almost entirely on hydropower and during the 2015–16 El Niño event, Malawi, Tanzania, Zambia and Zimbabwe all experienced electricity outages due in part to reduced rainfall. Climate risks must be built into planning, this is particularly true in many of Africa’s river basins because they are highly sensitive to changes in rainfall. The increasing importance of hydropower and the potential for increasing levels of rainfall variability under climate change, underscore the need to incorporate climate risks into infrastructure planning in Africa.

There is no question the planned increase in hydroelectricity generation in Africa presents both significant opportunities and also challenges. It will assist the economic development of the continent, as greater electrification will drive industrialisation and support the creation of more secondary and tertiary industries. All these come with several socio-economic opportunities. Also, increase in water storage capacity will assist the agro-industry, by reducing its reliance on rainfed agriculture. However, an over reliance on dams could threaten food, water and energy security during times of drought, and would present challenges to a wide-range of communities that rely on the natural flow of water in rivers. Also, the boom of industrial and household activities around centralized power-stations and artificial water reservoirs can cause local and regional degradation in air and water qualities if strict rules and regulations for emissions and/or injections of pollutants are not properly put in place. These emerging threats and challenges need to be assessed with the water-energy-food nexus and life-quality in mind. If African countries seek to harness the wide benefits that their rivers provide, they must also learn from previous mistakes, minimise and mitigate the negative effects of the ongoing dam building.

The number of challenges that Africa presents in terms of energy-water-food nexus and life-quality are significant. As such nexus has also several feedback impacts on eco-system services and bio-diversity. Furthermore, the lack of adequate management of available water resources is contributing to an existing and accelerating water crisis in the African continent. Changes in climatic patterns are also expected to have impacts on crop yields, which in combination with population growth will lead to severe additional stress on water resources that otherwise would have to be dedicated to increase agricultural productivity. Under these scenarios, future water needs from the growing African energy sector may play a key role when combined with changes in water availablity and the future increasing demands from agriculture. A proper analysis of the water requirements of the African energy sector is important for an effective future planning and management of water, energy and food resources in Africa.

This said, an important and interesting issue is the impacts of water needs for energy use and production on the natural water cycle on local and regional scales in Africa, also probably on the global scale because of evaporation from an increasing number of artificial reservoirs behind the planned hydropower dams in the arid and semi-arid regions in Africa.

At this stage we give only one example on the ongoing plans in Ethiopia for hydropower production. However, sustain-earth.com will continue in detailing the what, why and how issues in the “water-energy-food nexus” in Africa. Follow the story here (https://youtu.be/NbKoXlYUNY0).

The Magic of DIY – How to Make Your Own IPHONE 📱

What would Steve Jobs (https://sv.m.wikipedia.org/wiki/Steve_Jobs) says if he would have seen his life-time invention to be RECYCLED in the second-hand market in tiny small pieces, parts and components? Reverse Engineering ‘RE’ doesn’t leave any product, what-so-ever until it is copied, re-engineered and put together again and again even in its best original form. Every piece, part, component and/or even the smallest screws and contacts of any smart phone, including Iphone, or/and Ipads are now re-coded, re-sorted, put on shelfs, re-packed and sold in thousand of streets of China 🇨🇳. Also, for that matter anywhere else around the world. No wonder how curiosity, needs and motivations to survive van turn people to use their imagination to re-cycle and re-use even what we still define as SMART. It is the enormous, constant and pressing needs for reparation and maintenance of even the modern HIGH-TECK electronic devices and appliances have created new markets, series of supply chains and self-made employment around the world. High-speed production by automation in factories can be RE as needs and demand for services are huge and can save the economy of users. AI will also be copied no matter the level of intelligence and the recycling of intelligence will grow and flourish. Humans will always find ways to win over AI as the instinct of survival is an important attribute for search for better life. Intelligence is a key component for the survival of the fittest and it is why humans keeps expanding their intelligence specially with the accelerating access to knowledge and know-how through the Internet-Of-Things ‘IOT’. With the growing need and imperatives of sustainability, Recycling, Re-using and Re-creating can make our planet Great Again.

Yes we can, see here how you can build your own Iphone https://youtu.be/leFuF-zoVzA
