Why is environmental management a complex and huge task for society?

Environmental management is a complex and huge task for society because sufficient information is not available about the biophysical processes to predict and control them. The relation between humans and environment has become complex as industrialisation has accelerated the extraction of resources. This has affected ecosystems in ways which were not possible earlier. The industrial management systems are fragile and often vulnerable. This has also given rise to many environmental problems and risks. Disasters like the Bhopal Gas Tragedy are consequence of such hazards.
