The main environmental problem associated with plastics is their persistence in the environment. This is because most plastics are not biodegradable, meaning they are not broken down by natural processes like microbial action within a reasonable timeframe.
Plastics are non-biodegradable and accumulate in the environment, leading to pollution of land, water, and air.
While plastics themselves might not have direct biochemical synthesis activity, their disposal and breakdown into microplastics can release harmful chemicals into the environment. They do get released into water bodies and can enter the food chain. Many types of plastics contain additives that are harmful to humans and wildlife.
