Basically plastic bags are not biodegradable. Plastic bags thrown out as waste on lands do not decompose and remain there for a long time. It weakens the soil in hilly areas, makes the roots of trees exposed because of that, trees loose their strength to survive. Further disruption of soil causes washing off vegetation and nutrients that are in the soil. If plastic bags are burnt, they give out hazardous gases causing air pollution. At times, cattle's happens to swallow plastic waste while they are grazing; this causes them to be affected by digestion problems, which causes death.
