Biodegradable Plastics are superior to any other plastic.

Great! Thanks for accepting. First topic I would like to discuss is the impact of plastic on human health. I is well known that plastic is not a naturally occurring material, and nature does not treat it as such. Plastics such as polyethylene terephthalate (PET) wind up either washing up on the shores of our beaches and floating in the earths oceans. This brings up questions such as what this unnatural material does to our bodies if mother nature herself cannot digest the material. PET is a sturdy plastic that blocks oxygen water and carbon dioxide and is commonly used for water bottles, microwavable food trays and such. However, when these plastic objects are reused time and time again, it is a possibility that the plastic releases a toxin DEHA, which is known to cause liver problems, reproductive difficulties, and possibly cancer. Another chemical that is shown to cause adverse effects that stem from plastics is Bisphenol-A (BPA). When this chemical is found in excess in the human body, it has been proved to be dangerous in many ways. Humans re exposed to BPA on a regular basis every day, and the exposure is as follows: less than 0.0147 mg/kg bw/day for children, less than 0.0015 mg/kg bw/day for adults and 0.0100 mg/kg bw/day for workers. This chemical is found present in many people, including pregnant women who have passed BPA onto their infant children, and although no behavioral conditions were examined first, when the children reached to the age of three, specifically women, the children began exhibiting problems such as aggression, inattention, hyperactivity, depression, and anxiety. Roughly 130 studies around the world have taken place and many of which have determined it is a dangerous chemical, and consequently, several areas in the United States have pulled all BPA products off of the shelves. Studies also show that BPA causes a 25% increase in possibility to have heart disease and diabetes. Even the National Toxicology Program – Center For The Evaluation of Risks To Human Reproduction (NTP-CERHR) and the U.S. Department of Health and Human Services decided to research this plastic on the grounds of its "widespread human exposure, public concern for possible health effects from human exposures, high production volume, [and] evidence of reproductive and developmental toxicity in laboratory animal studies." On their studies, they came to the conclusions that there is a certain amount of concern to be held for the effects on the brain, behavior, and prostate gland in fetuses, infants, and children. It was also concluded that there was a minimal concern for children at an earlier age and the effects of BPA on their mammary gland causing puberty at an early age. Another bad impact that regular plastics have on the world is what it is doing to the environment. Plastic has only been produced for around 100 years, and humans are faces with the confusion of what to do with the waste almost everyday. Often plastic is disposed of improperly, and because of this, it has wound up lost in the sea, on the beaches, or buried in the soil in the earth's forests. Plastic also has a well known effect on animals, causing millions of them to die each year by getting trapped in 6 pack rings and blocking the tubes for the digestive tract once consumed. However, these problems can be treated with the availability of biodegradable plastics, which could replace the plastics in use today with something that the earth can actually break down and recycle itself. These plastics can be susceptible to decomposition, from photodegradation and biodegradation. Once these products are decomposed, they only turn into natural by-products such as carbon, hydrogen, and oxygen.There are also different types of these plastics that can be used, such as Polyglycolic acid (PGA), Polylactic acid (PLA), Polycaprolactone (PCL), Polyhydroxybutyrate (PHB), Polyhydroxyvalerate (PHBV), Polyvinyl alcohol (PVOH), Polyvinyl acetate (PVAC), Polyenlketone (PEK), and several others are always being invented. Biodegradable plastics can very well be the solution to the current plastic problem that is injuring our earth and our bodies. It is much preferred to use something that is more natural and the earth actually recognizes it as something familiar instead of an entirely new and alien substance synthesized by humans.
