mass production of nitrogen fertilizer became available. Nitrogen is one of the major nutrients that is required by the plants at large quantities for their growth. His innovation brought a revolution in agriculture production. Since 1900 to 2000 the world population has increased by 5 billion and rose to 7 billion. Food production for this additional amount of people was possible to a large extent due to the use of artificial ammonium fertilizer. Aside from fertilizers‚ ammonia is also needed in

Over the past century‚ as a side effect of food production‚ humans have been releasing huge amounts of nutrients‚ specifically nitrogen and phosphorus into water resources like lakes‚ rivers and even oceanic coasts. This has caused enormous growth in algae populations‚ literally choking the life out of aquatic ecosystems and polluting water for humans as well. These “Harmful Algal Blooms” (HAB’s) or green tides as some call them can produce toxins that can hurt animals and humans alike turn water
