As cities around the world expand, fertile land is disappearing under concrete and asphalt. Like human skin, the Earth's sensitive surface needs protection from the sun, wind and cold. Depletion of the soil through deforestation, over-fertilization and overgrazing can turn land into desert. Monoculture plantations need large amounts of fertilizer and pesticides to remain productive. Whether resulting from industrial leakage, disaster or weapons, or from years of over-fertilization: once soil is contaminated, fixing the damage is costly and time-consuming.
It takes 2,000 years for nature to produce a 10-centimeter (4-inch) layer of fertile soil that holds water and nutrients, and where plants can grow.
Worldwide deterioration of soil quality is a disaster in the making, warn experts like Jes Weigelt of the Institute for Advanced Sustainability Studies in Potsdam, Germany. Arable land is being lost at a rate of 1,000 square kilometers (386 square miles) per day, Montanarella says. Removing, sealing and compacting soil kills off the billions of microorganisms, bacteria and fungi that make a handful of earth a living microcosm. Since spiritually oriented biodynamic agriculture began in Germany 90 years ago, its popularity - and controversy - have spread across the globe.
Rapa Nui, in the South Pacific between Chile and Polynesia, is famous for its monumental head statues.
Greenland and its colonial big brother Denmark are appealing to the European Union to lift the ban on commercial seal hunting. Soil experts in the European Commission hope that the worldwide protection of soils will find a prominent place in the new sustainability development goals (SDGs) to be adopted by the UN general assembly in fall. For Montanarella, soil conservation counts among the most important requirements for sustainable development. EU countries import 35 million tons of soy beans and soy meal from north and south America every year - to use as feed for pigs, chickens and cows.
Cultivation of primarily genetically modified soy for export uses land in developing countries that could go toward sustainable agriculture. But even in industrialized countries like Germany, globalized industrial livestock farming presents a pollution problem. Building more sustainable agricultural practices benefits not only the environment, but also human health, said Swiss agriculture and development expert Han Herren. New research shows we can feed the growing population without destroying our forests a€“ if we eat less meat. Food insecurity and vulnerability to natural disasters are becoming increasingly linked, according to the UN's latest World Risk Report.

The world is running short of phosphate ore for chemical fertilizers; recovering phosphate from waste and reducing phosphate use in phosphate rich countries can alleviate the shortage and simultaneously prevent environmental pollution. Phosphorus scarcity has been gaining increased attention on the research and policy agenda in recent years due to the 800% phosphate rock price spike in 2008. The extensive use of phosphate fertilizer has led to leakage into waterways and lakes causing eutrophication (nutrient enrichment leading to algal bloom). Plants acquire phosphates from the soil, but phosphate availability is limiting for plant growth and crop yield in more than 30 % of the world’s arable land. Poor availability of P in soils and consequent P-deficiency are major constraints to crop production globally. As the global supply of phosphate ore declines, the world must turn to recycling phosphorous and to more economic use of phosphate in agriculture. Driven by the goal of local food security, this phosphorus recovery system in southern Niger involves 700 households (eight villages) in the recycling of nutrients and organic matter from human excreta via simple urinals and waterless toilets. It has been suggested that the phosphate fertilizer gap in developing countries can be immediately relieved. Green manure consists of growing a crop, such as clover or grass, which is ploughed under the soil to improve fertility.
Crop and microbial genetic engineering is being promoted for relieving the global shortage of phosphate ore. Low phytate rice was produced by transforming rice with a small RNA (RNAi) gene driven by a promoter from rice, which reduced production of phytate in rice grain. The world is facing an immediate crisis in the decline in the availability of phosphate ore to provide for the food needs of globe.
Phosphorus recovery from bones is something we certainly do having learnt the technique from Latin American based organisation MasHumus. Perhaps taking that process and using it to reduce as many animal carcases as possible to compost and spreading that on and around the land would be of benefit in areas that are deficient in phosphorous. The above map was created using the geographic references from this era in the AP World History curriculum.
Key Concept 2.1 Codification and Continued Development of Religious and Cultural TraditionsAs states and empires increased in size and contacts between regions multiplied, religious and cultural systems were transformed. As the early states and empires grew in number, size, and population throughout Afro-Eurasia and the Americas,  they frequently competed for resources and came into conflict with one another.
With the organization of large-scale empires, the volume of long-distance trade increased dramatically.


Microorganisms are suffocated under this artificial surface, and above it rainwater flows away rather than seeping into the soil.
Large areas can dry out, and ploughing can dislodge the top layer so that it is blown away by the wind. Climatic factors like drought become a catalyst in a chain reaction - that is set in motion by human activity.
According to official sources in China, nearly one-fifth of agricultural land there is contaminated. To protect fertile soils worldwide, the United Nations has declared 2015 International Year of Soils. He clarified that the biggest losses are from the construction of roads, cities and industrial facilities. Its barren landscape, to some a symbol of ecological collapse, is now the target of reforestation efforts. These SDGs provide the political foundation for sustainable development in developing and industrialized nations.
The environmental impacts of factory farming "ultimately fall on the taxpayer," said Ehlers. He hopes that aiming more public attention to the issue of soil depletion on the national and EU levels will lead to more sustainable policy-making, and development of organic agriculture.
Recognized with the Alternative Nobel Prize Right Livelihood Award in 2013, Herren proposed that a variety of foods be cultivated. But with one in nine people already underfed, a change in how we think about food cana€™t come soon enough. Algal blooms are dangerous because some algae are toxic and the blooms also remove oxygen from the waterways. Maize is the most widely cultivated crop around the world, and commonly affected by phosphate deficiency, but the underlying molecular basis of response mechanisms is still unknown. The application of fertilizer can compensate for low availability in cropping systems, but high phosphate input causes severe environmental problems.
In the European Union around 25 % of phosphorus in municipal wastewater is currently recovered and reused, predominantly as sludge. Animal bone products (derived from the grinding or thermal treatment of raw bone) contain a greater concentration of plant-available phosphorus than commercial phosphate rock fertilizer. Deep rooted legumes will extract phosphate from deep soil strata that are not available to the roots of food crops. Silencing the phytate synthesis gene led to a substantial reduction in seed phytate levels without hampering the growth and development of transgenic rice plants [24]. There is a critical need to recover the phosphate leaking from sewers and farm lands and polluting the environment. Even in Australia with its phosphorous deficient soils it is possible to grow quite diverse crops. Religions and belief systems provided a bond among the people and an ethical code to live by.
New belief systems arose out of Hinduism and the Hebrew (Judaism)religion  and cultural traditions emerged and spread, often asserting universal truths. Empires and states developed new techniques of imperial administration based, in part, on the success of earlier political forms.
Existing land and water routes became the basis for larger transregional (acrossseveral regions) trade, communication, and exchange networks in the Eastern Hemisphere. Through resource extraction, land that could provide wildlife habitat, or be used for agriculture or human habitation, is lost. Plasma low phosphorus concentration suppresses erythrocyte synthesis and storage of 2,3-diphosphoglycerate (2,3-DPG), which plays an important role in the affinity of haemoglobin for oxygen.
The transcriptional response of maize roots to phosphate starvation at 3 days after deprivation revealed a total of 283 responsive genes, 199 and 84 up- and down-regulated respectively by 2-fold or more. Crop production of the important legume, the common bean Phaseolus vulgaris, is often limited by low phosphorus in the soil. However, in most cultivated soils, organic phosphorous comprises 30–80 % of the total phosphorous, and approximately 60–80% of organic phosphorous exists in the form of phytate, which is not directly available to plants. Crop residues (such as straw, husks and stalks) are an important and common source of phosphorus, while organic waste from food processing and production (such as peelings, oil cakes, food preparation and plate waste) can also be productively reused for their phosphorus content.
For instance, between 2008 and 2011 the livestock herd in Ethiopia comprised more than 50 million cattle, 23 million sheep and 22 million goats, and would have yielded approximately 192 000 to 330 000 tonnes of bone waste annually.
Crotalaria (rattlepods) proved to be a suitable green manure in maize and bean cropping systems in Uganda [21]. Chinese researchers found that a gene Ta-PHR1-A1 is involved in phosphate signalling in wheat and, when over-expressed, it increased phosphate uptake and grain yield of wheat [25]. That should be the primary step to protect the health of the human population, at the same time protecting the environment. This high value product can be solubilized and applied or added to biofertiliser to be digested by microbes leaving the phosphorus chelated in solution and therefore plant available. These shared beliefs also influenced and reinforced political, economic, and occupational stratification.
The Assyrian, Babylonian, and Roman empires conquered various Jewish states at different points in time. In doing so, they built powerful military machines and administrative institutions that were capable of organizing human activities over long distances, and they created new groups of military and political elites to manage their affairs.


Symptoms of nervous system dysfunction, such as weakness, apathy, a bedridden state, and intention tremors, are also observed in severe hypophosphatemia [10]. Pi-responsive genes were found to be involved in sugar and nitrogen metabolic pathways, ion transport, signal transduction, transcriptional regulation, and other processes related to growth and development.
The genotypes, BAT477 and DOR364 of the common bean have contrasting responses to phosphate starvation. Thus, improving phytate bioavailability is important for plant phosphorous nutrition, and for sustainable agricultural development as phosphorous ore resources are depleting worldwide [14]. Initially developed by the University of British Columbia in Canada to reduce the occurrence of pipe blockages in advanced wastewater treatment facilitates, the Ostara nutrient recovery technology recovers phosphorus and ammonium from wastewater treatment plants via a fluidized bed reactor [18]. Recycling of these bones would have yielded around 28 to 58 % of annual phosphorus fertilizer supplies to Ethiopia over the same period. Vetch (Vicia) and oat green manures are effective in relieving nutrient deficiency in the soil of central Mexico [22]. Several publications deal with transgenic modifications leading to improvements in phosphate uptake and utilization in food crops. Applying mineral fertilisers to crops simply bypasses the process of developing healthy and deep top soils. Religious and political authority often merged as rulers (some of whom were considered divine) used religion, along with military and legal structures, to justify their rule and ensure its continuation. These conquests contributed to the growth of Jewish diasporic communities around the Mediterranean and Middle East. As these empires expanded their boundaries, they also faced the need to develop policies and procedures to govern their relationships with ethnically and culturally diverse populations: sometimes to integrate them within an imperial society and sometimes to exclude them. The exchange of people, technology, religious and cultural beliefs, food crops, domesticated animals, and disease pathogens developed alongside the trade in goods across far-flung networks of communication and exchange.
Severe malnutrition contributes up to 50 % of childhood mortality in developing countries, and is frequently characterized by electrolyte depletion, including low total body phosphate in children treated at Kenyatta National Hospital with kwashiorkor (protein deficiency). The expression patterns of maize inorganic phosphorus transporters, acid phosphatase, phytase, 2-deoxymugineic acid synthase, POD and MYB transcription factors were validated in root response to low phosphorus stress. Plants with the BAT477 deficiency tolerant genotype showed higher phosphate content and root biomass than DOR364 plants under phosphate starvation. Phytic acid (also known as inositol hexakisphosphate in salt form), a saturated cyclic acid, is the principal storage form of phosphorus in many plant tissues, especially bran and seeds. Wastewater centrate (water leaving a centrifuge after most of the solids have been removed) influent from sludge dewatering side-streams enters the reactor from the bottom.
Importing an equivalent amount of phosphorus fertilizer costs approximately US$ 50 to 104 million. Using green manures provides some immediate relief to the soil nutrient deficiency in developing countries, but in the long run, may require some phosphate fertilizer to maintain food crop productivity.
However, those modified crops do not have the ability to fabricate phosphorus to replace that required for human nutrition in the long run. Religions and belief systems could also generate conflict, partly because beliefs and practices varied greatly within and among societies. Jesus's teachings were recorded in the Gospels and developed in other writings, particularly by his disciple, Paul.d. In the United States, only 5% of the phosphate extracted from nature for food was found to be ingested by humans, while the remainder was lost to the environment [8]. Among children with mild, moderate, and severe hypophosphataemia, 8, 14 and 21 % died respectively [11]. Phytate is not digestible to humans or non–ruminant animals, so it is not a source of either inositol or phosphate if eaten directly. Developing countries already have access to an indigenous supply of phosphate fertilizer, in the form of organic waste products.
By expanding their boundaries too far, they created political, cultural, and administrative difficulties that they could not manage. In England, the phosphates discharge from urban sewage treatment plants was greater than the agricultural discharges into rivers and the urban phosphorous discharges have begun to be remedied by phosphorous stripping prior to discharge to the environment [9].
It is safe to say that insufficient phosphate is a serious problem that will worsen as the world’s supply of phosphate ore shrinks. Moreover, phytic acid chelates and makes unabsorbable important minor minerals such as zinc and iron, and to a lesser extent, also macro minerals such as calcium and magnesium [15].
The resultant struvite is then harvested from the reactor, dried and packaged onsite for sale. By tapping into this resource, these countries can secure a significant fraction of their phosphorus demands without relying on international markets or the benevolence of rich countries [20].
Phytate is a major storage form of phosphorous in the seeds of grains and legumes and during seed germination the plant enzyme phytase is activated releasing orthophosphate for plant growth [16]. It is also true that developed countries would benefit greatly from recovering bone meal from food waste on a scale much larger than the current production of bone meal.
As the Roman Empire began to fall in the West, Christianity became a more prominent religion as the focus on ever-faithful God and never ending heavenly reward was more comforting to increasing number of people.
