    So much ignorance. Just one example: human and most plants cannot pull nitrogen from air. (Actually only ferns and moss can.) This is the reason why the Haber process, invented a century ago, was such an important development in guaranteeing the food safety of the people.

    Dear Yair,

    You are correct in your statements if you are referring to nitrogen in its original form. But for clarification purposes and for the benefit of our readers, the air humans breathe is a mix of gasses and nearly 80% of that mix is nitrogen. Nevertheless, nitrogen in the air, N2, is inert, or non reactive and this bond takes a rather large amount of energy to break.

    Humans can, through the use of cryogenics, separate pure gases, such as nitrogen, from air by cooling it until it liquefies, then distilling it. The process is energy intensive but can produce high purity nitrogen.

    The process was invented by Dr. Carl von Linde in 1895.

    Furthermore, a technology has been developed by the University of Notttingham, which enables all of the world’s crops to take nitrogen from the air. N-fix is now a patented technology based on a bacteria Gluconacetobacter diazotrophicus (Gd) for coating plant seeds in order to create a symbiotic relationship within the plant enabling it to substitute the nitrogen it normally takes up from the soil with atmospheric nitrogen.
