Use of plastic has caused many environment-related problems. For this, which of the following statements is correct?

Synthetic plastics are largely non-biodegradable – microorganisms cannot break them down readily, so they persist in the environment for hundreds of years, accumulating in soil, water bodies and oceans (as microplastics) and causing serious ecological damage. Plastics can in fact contaminate water and food, can undergo (slow) chemical degradation, and many plastic additives are harmful to humans, so the other options are incorrect.
