Since polypropylene contain only carbon and hydrogen atoms, it does not poison environment after its disposal. However high melting point suggests that deterioration time in the land field will be long. ammendment: really? how exactly will it break down? and what time frame. to say it does not poison the environment after disposal is untrue.
There are two types of polymers, which are natural and synthetic. Although natural polymers do not affect the environment, synthetic polymers do.
Synthetic polymers are anything that is manufactured or influenced by humans. Due to this, these types of polymers release reactants which are hazardous; both to humans and the environment.
Synthetic polymers, which include plastics, rubber, adhesives, and Styrofoam cannot be degraded into the environment, causing a buildup of these chemicals all at once, causing a release of any "excess" chemicals into the environment.
From there on, polymers create garbage loads, and chemical reactants that effect the environment, and spread around. Therefore effecting anything grown or eaten around it. This could call chemical poisoning to the greenery, animals, and living organisms around it.
Not all polymers are bad. In fact humans are made up of polymers. But polymers from sources such as crude oil synthesized into plastics release toxins as they break down. When you burn plastics synthesized from crude oil feedstock, carbon dioxide and dioxins can be released into the air if smoke is not properly filtered as they are in high quality waste-to-energy incinerators. Also plastics are non biodegradable and so landfills are used to bury the plastic this takes up space and also costs money because there is not enough room for all the waste. Therefore plastics are banned in some areas.
Polymers are very unreactive so this makes them hard to dispose of which cause litter and landfill sutes to be filled. Most polymers are non-biodegradable so last for many years in rubbish dumps. It is possible to include cornstarch to the polymer to make it break down quicker, so polymers can be recycled. To do this the polymers must be seperated from eachother which can be difficult and expensive. However it would reduce the disposal problems and the amount of crude oil used. Many people still throw carrier bags away, knowing the environmental impacts. This is why, especially in the UK, there is a charge for carrier bags, so people are encouraged to reuse their plastic bags and not to throw them away!
To make plastics
Ha Ha Ha actually we can't differentiate between plastic and polymer because plastic itself is made of polymer.
Cellulose: Found in plant cell walls, it is the most abundant natural polymer. Chitin: Found in the exoskeletons of arthropods and the cell walls of fungi, it is a versatile natural polymer. Casein: A protein found in milk that can be used to create biodegradable plastics.
The plastic polymer from which plastic bags are typically made is polyethylene.
Thermosoftening plastics are held together by weak intermolecular forces that allow the polymer chains to slide past each other, making the material soft and malleable. When heated, these forces weaken further, allowing the polymer chains to move more freely, resulting in the plastic becoming molten and easily molded into different shapes.

bad efects of plastics
Yes, plastic is typically made from polymers. Polymers are long chains of repeating molecules, and plastics are derived from these long chains. The properties of plastics can vary depending on the specific type of polymer used in their production.
Plastics are usually synthetic organic polymers. The first step to manufacturing plastics is to get the materials. Step 2 is to synthesize the polymer. Step 3 involves compounding the polymer into a material that can be used and step 4 involves shaping the plastic into it's form.
they are plastics that can be bad for our environment

not usually, but would depend on the polymer
It's not that what they make plastics with.
the M16 assault rifle is composed of steel, aircraft grade aluminum, composite plastics, and polymer
The polymerization reaction produces rubber and plastics from organic molecules. In this reaction, monomers join together to form long chains of repeating units, creating the polymer structure of rubber and plastics.
