Green crime is difficult to control is bc the rich and powerful often benefit from it, while its the poor who suffer the harms. Marxists: the powerful establish laws that are in their favour, so if they benefit from harming the enviroment, they are unlikely in making it a criminal act. Exploitation of hte natural enviroment has long been part of making a profit in the capitalist system (extracting oil & minerals, deforestation - pollution) eg shell in nigeria. Now companies have to pay fines if they pollute, however companies choose to carry on polluting & just pay the fines.
