As far as the environment of Papua New Guinea is concerned, there have been rain forest loss as a result of growing commercial demand for tropical timber; unsustainable logging practices result in soil erosion, water quality degredation, and loss of habitat and biodiversity; large-scale mining projects cause adverse impacts on forests and water quality (discharge of heavy metals, cyanide, and acids into rivers); severe drought; inappropriate farming practices accelerate land degradion (soil erosion, siltation, loss of soil fertility); destructive fishing practices and coastal pollution due to run-off from land-based activities and oil spills.
