Hello,

Here there are some issues emerges in enforcement of national environment legislation .

The precautionary principle This principle has evolved to deal with risks and  uncertainties faced by environmental management. The principle implies that an ounce of  prevention is worth a pound of cure— it does not prevent problems but may reduce their  occurrence and helps ensure contingency plans are made.

The polluter-pays principle In addition to-the obvious—the polluter pays for the damaged caused by a development—this principle also implies that a polluter pays for  monitoring and policing. A problem with this approach is that fines may bankrupt small  businesses, yet be low enough for a large company to write them off as an occasional  overhead, which does little for pollution control.

Freedom of information: Environmental planning and management is hindered if the  public, NGOs or even official bodies are unable to get information.

I hope this helps you .

Thank you !
