Rubber bags are very harmful to people. The use of plastic bags for food is read more and more, it causes food to be contaminated but the poison contains nylon. We will be able to throw it somewhere as if it would pollute the land or make the living tree alive and grow and it would be polluted and would not pollute it or cause it to pollute the environment. Nitrite can cause cancer. So I hope everyone can reduce the use of nylon bag.
