write a conclusion on the project topic Plastic:useful for minutes,harmful for decades

Dear Student,

To conclude, though, at many instances, plastic seems to be useful, the ham it does is for decades. It is a non biodegradable substance and causes land and water pollution. Burning of plastic also causes air pollution. Plastic bags when consumed along with food by animals cause harm to their life. Plastic bags can cause blocking in sewage line.
