What possible sources of oxides of nitrogen could have eluded us?
We have looked at agriculture and fossil fuels. We should check on biofuels. They could be a major source, since we are looking at them as alternatives to fossil fuels. The nylon industry could also be a significant source. There could be others too which we haven’t looked into. Why has the nitrogen cycle not been studied? It seems that the emphasis on the carbon cycle has worked to the detriment of research on the nitrogen cycle. What are the precautions that can be immediately adopted? Only 30 per cent of the nitrogen fertilisers used in agriculture is consumed. The unused nitrogen enters the nitrogen cycle and disrupts it. We should use fertilisers more efficiently. Your views on the ozone depletion and global warming. The ozone hole problem has been solved. We have found replacements to ozone depleting substances like chloroflurocarbons. However it will take about 70 years to get rid of chloroflurocarbons from the atmosphere. The global warming problem, however, is far from being s
