Scientists Beginning to Sound Warnings About Atmospheric Nitrogen Compounds
B. McPherson This short film explains very well the greenhouse effect on Earth. While the world is focussing on the production and release of carbon dioxide into the atmosphere, other gasses are quietly adding to the catastrophe. Methane is a potent greenhouse gas and nitrous oxide is 300 times more efficient at keeping the Earth warmed. While much of the Earth’s atmosphere is made up of the element nitrogen, it is the nitrogen in reactive compounds that is starting to worry atmospheric scientists. The Green Revolution was made possible by the industrial production of chemical fertilizers. It, combined with antibiotics has allowed the Earth’s population of humans to swell from 1.6 billion at the beginning of the 20 th century to seven billion this year. Nitrogen is a key nutrient in plant growth. Unfor...
