Nevertheless, this problem can be tackled by the authorities having strict laws towards industrial activities in enterprises.More specifically, the state can set a limit on the extraction of Greenland and besides, frequently examine the wastewater treatment in factories. For this reason, if there were any shortcomings in radically treating sewage before releasing it into the environment coupled with the overuse of exploiting green spaces, those must receive a monetary fine and a ban from continuing to go to work for a time period. Vietnamese authority is a relevant example, which without informing, found some factories skipping the waste purification, afterwards, forcing it to totally be closed down three years later and compensate for nearly five hundred million Vietnam dong for one violation.
