In the wake of green revolution, use of inorganic fertilisers and pesticides has increased manifold for enhancing crop production. Pesticides, herbicides, fungicides, etc., are being increasingly used.
These incidentally, are also toxic to non-target organisms,that are important components of the soil ecosystem. Do you think these can be biomagnified in the terrestrial ecosystems? We know what the addition of increasing amounts of artificial fertilisers can do to aquatic ecosystems vis-à-vis eutrophication.
The current problems in agriculture are, therefore, extremely grave.
