We have the soil, the decaying body of the host (no life, dead cell), the atmosphere and gases and temperature & climate.
The nitrogen cycle is one of the biogeochemical cycles that occurs to maintain balance and matter distributed through the biosphere. This cycle enables nitrogen to develop from a decaying organism back to the air and used again for other natural processes.
The emissions of carbon dioxide would reduce because then they will consume less gasoline. Instead of coal burning, this would reduce the overall concentrations of greenhouse gas emissions and generate energy from wind.
