The Haber-Bosch process uses a catalyst or container made of iron or ruthenium with an inside temperature of over F C and a pressure of around atmospheres to force nitrogen and hydrogen together Rae-Dupree, The elements then move out of the catalyst and into industrial reactors where the elements are eventually converted into fluid ammonia Rae-Dupree, The fluid ammonia is then used to create fertilizers.
Today, chemical fertilizers contribute to about half of the nitrogen put into global agriculture, and this number is higher in developed countries. Today, the places with the most demand for these fertilizers are also the places where the world's population is growing the fastest.
Some studies show that about "80 percent of the global increase in consumption of nitrogen fertilizers between and came from India and China" Mingle , Despite the growth in the world's biggest countries, the large population growth globally since the development of the Haber-Bosch process shows how important it has been to changes in global population.
The current process of nitrogen fixation is also not completely efficient, and a large amount is lost after it is applied to fields due to runoff when it rains and a natural gassing off as it sits in fields.
Its creation is also extremely energy-intensive due to the high temperature pressure needed to break nitrogen's molecular bonds. Scientists are currently working to develop more efficient ways to complete the process and to create more environmentally-friendly ways support the world's agriculture and growing population.

The Haber Bosch Process has an ecological impact since soil fertilizers are easily soluble in water and as a consequence, easily transported from their designated soil in run-off waters.
When they reach large water bodies a phenomenon known as eutrophication happens — the exponential, unnatural growth of algae that covers the surface of the water body, preventing sunlight to reach submerged species. As a consequence, submerged organisms are unable to do photosynthesis and die. Methaemoglobinemia is described as the reduced ability of the blood to carry oxygen due to reduced levels of normal hemoglobin.
One of the most common causes is nitrate in drinking water which can be originated by the leeching of nitrogen fertilizer into groundwater-drinking water. Since it that particularly affects infants who show signs of blueness around the hands, mouth, and feet, the syndrome got to be known as the Blue Baby syndrome. According to the World Health Organization , some children may have trouble breathing as well as vomiting and diarrhea. In extreme cases, there is marked lethargy, an increase in the production of saliva, loss of consciousness, and convulsions, and even death.
According to Professor Nishibayashi from the University of Tokyo, he and his team found, in a study published in Nature , a new way of synthesizing ammonia which is far cleaner, easier and cheaper than the Haber Bosch process. Moreover, the Samarium-Water Ammonia Production SWAP process discovered requires only readily available lab equipment and recyclable chemicals, whereas the Haber-Bosch process requires large-scale industrial equipment.
Nishibayashi suggests that anyone with the proper source materials can perform SWAP on a table-top chemistry lab. From a sovereignty perspective, the SWAP technique looks promising in the sense that it can be used by those who would be otherwise stopped by the large capital investments required in the case of the HB process, decentralizing the process of ammonia production.

What is the Haber Bosch Process? The Reactants of the Haber Bosch Process: Hydrogen and Nitrogen Understanding how the reactants for the Haber Bosh process are obtained helps to further explain its ecological impact.
How Hydrogen is Obtained for the Haber Bosh Process Hydrogen was typically obtained via water hydrolysis, which consists of an electric current passing through water and separating oxygen from hydrogen.
Why the Haber Bosh Process and the Need for Fertilizers At the start of the 20th century the world population was growing exponentially, and so was life expectancy thanks to medical progress and technological developments. The Cons of the Haber Bosch Process The Haber Bosch Process Leads to Eutrophication and Biodiversity Loss The Haber Bosch Process has an ecological impact since soil fertilizers are easily soluble in water and as a consequence, easily transported from their designated soil in run-off waters.
The Haber Bosch Process and the Blue Baby Syndrome or Methaemoglobinemia Methaemoglobinemia is described as the reduced ability of the blood to carry oxygen due to reduced levels of normal hemoglobin.

Gig Economy — What Is It? Over the next few years he developed other more lethal and nasty gases, such as phosgene and finally mustard gas, all of which were used against Allied troops. His wife also a chemist objected so much to his 'immoral' role that she committed suicide by shooting herself in his living room. The very next day Haber went to the Eastern Front to continue his gas tests Haber received the Nobel prize in for his ammonia process and 'contributions to agriculture', but because of his association with chemical weapons, there were many objections to him receiving the prize.
In fact he was regarded as a war criminal by the Allies, but was never prosecuted, probably due to the political embarrassment it would have caused to prosecute a Nobel prize winner for war crimes! After the war he continued to make poison gases for the German government under the cover of projects to make insecticides.
One gas he invented was a cyanide-based gas named Zyklon B. This is quite ironic, since Haber was originally of Jewish descent although he renounced his religion in favour of Christianity to 'appear more German' - he didn't realise that this gas was to be used 15 years later in the Nazi death camps to kill his Jewish countrymen.
When the Nazis came to power in the early s, they treated him with suspicion because of his Jewish heritage, and when they started deporting his Jewish technicians, Haber decided he could no longer remain in the country he loved, and so fled to Switzerland. He remained there in self-imposed exile until his death some years later.
