There are many plastics and even more polymers. We usually reserve the terme "plastic" to synthetic materials but there are plastic-like materials in nature, like amber. Polymers includes things like proteins and DNA, basically what life is made of. So saying that releasing "bad things" (what does it even mean?) is a fundamental property of polymers is a bit too much. What "bad things"? What plastics? What dose?
