A solution to our nitrogen deficit and pigeon problem in one!

Scientist have claimed our world has too little nitrogen but also too nitrogen, at the same time!

This paradox exists because over the last century, humans have been pioneering industrial agricultural which has more than doubled the global supply of reactive nitrogen which becomes a pollutant, that is concentrated in streams, inland lakes, and coastal bodies of water, sometimes resulting in eutrophication, low-oxygen dead zones, and harmful algal blooms.

Simultaneously rising carbon dioxide and other global changes have increased demand for nitrogen by plants and microbes, leading to a deficit of nitrogen.

Humans have been using nitrogen long before industrial agriculture, one ingenious invention for harvesting nitrogen became so popular that the 16th and 17th centuries, that the idea spread across India and then to the United Kingdom and France were only the richest people were allowed to build the invention because of the potential to use the nitrogen to make explosive materials.

In the middle east this invention is still be used today, find out how they work by watching the video below and can you guess how all this is related to pigeons?
