nitrogen cycle

Nitrogen is an essential component of amino acids and the main element of atmosphere which rounds upto four-fifth of atmosphere. But now the burning of fossil fuels adds extra notrogen and nitrous oxide to atmosphere which pollute the ecosystem. Another major issue is that it adds to the green house effect, which is the heating of surface of the planet.It cause acide rain which pollutes earth's atmosphere,water and soil. when it goes through the soil,it harms the nutrients like calcium. I think the only way to stop this upset is by dentrification which means that we should use nitrogen nutrients as energy source and return nitrogen molecues into the atmosphere. Engineers are working on this.
