No reason for them to be. Plastic can be recycled or reused. Some are biodegradable, and break down when left exposed to weather and sunlight.

When plastics are burnt, they release toxic fumes and chemicals into the air, such as dioxins and furans, which are harmful to both human health and the environment. Burning plastics also contribute to air pollution and climate change by releasing greenhouse gases like carbon dioxide. It is not recommended to burn plastics due to these harmful effects.
The types of plastics that are compostable are typically ones that can be broken down in compost conditions that leave no carbon footprint on the environment. Many of these plastics are made out of corn starch. Also, plastics cannot be recyclable if they are compostable.
This question is not worth answering.The "enviorment" does not exist, "which are not harm" is incorrect grammar.If the question had read "which will not harm the environment" it could be worth answering.Wikipedia says:Biodegradable plastics are plastics that will decompose in the natural environment. Biodegradation of plastics can be achieved by enabling microorganisms in the environment to metabolize the molecular structure of plastic films to produce an inert humus-like material that is less harmful to the environment.
they are plastics that can be bad for our environment
Plastics that can be broken down by microorganisms are known as biodegradable plastics. These types of plastics can be decomposed into natural elements like water, carbon dioxide, and biomass by bacteria, fungi, or other microorganisms, helping to reduce their impact on the environment.
we can protect our environment by telling our socity about harmful uses of plastics ,by not throwing plastic any where alone ,by using cotton bag instid of using plastic bag etc .
Thermosoftening plastics soften and can be given any shape when hot. The different types thermosoftening plastics are Polyethylene, Polystyrene, Poly Vinyl Chloride, ABS plastics.
Certain types of bacteria can be harmful to the environment. Others help with natural processes like decomposing and stuff like that. So, it depends what kind of bacteria you are talking about.
Plastics are cheap and can be molded into many things. One drawback to using plastics is they harm the environment.
