5.APPLICATION OF PLASTICS: Plastics play an important part in our life. Plastics ' versatility allow it to be used in everything from baby toys to spaceship, from soft drink bottles to the refrigerators in which they are stored. From the car you drive to work and from the television you relax yourself when you get home. Plastics help make your life less demanding and better. So how could it be that plastics have turned out to be so broadly used?
The reason plastic is used in many products is because it can withstand up to tons of pressure per cm3, is cheap, is durable, and finally, there is no worry for discoloring. But these days, plastic is becoming a major problem the world has to deal with. Plastic is thrown into the ocean, and it is breaking down into very small pieces, and killing marine life, as they mistake those pieces to their prey. As a matter of fact, nearly all plastics are recyclable, but it 's the recycling companies ' machines that refuse to recycle that kind of plastic(eartheasy.com). I.
After the invention of different methods for the polymers’ manufacturing, the industry of plastics developed significantly. Plastic has several essential advantages, such as light weight, durability, an available price compared with other materials and an ability to be easily molded (Andrady and Neal 2009). That is why plastics are progressively more used in many areas; for example, in packaging, transportation, medicine, sport, agriculture, electronics, building and construction. By controlling the temperature inside the package using oxygen scavenger technology and gas-flush packaging, it is possible to provide storage and secure of products (Andrady and Neal 2009). Therefore, plastics have a great contribution to the safety of water and food packaging, and subsequently to the consumers’ health.
Plastic Bags: The Enemy of the Environment Plastic is a commodity that people use everyday which makes daily life easier and safer. People take pills, use cell phones, and wear bike helmets in addition to a plethora of other activities, but tend to forget that one common element in all of them is the use of plastic. One of the main sources of plastic that has been polluting the environment over the last few decades are plastic bags. Plastic bags can be found in nearly every store to hold groceries, accessories, or toys. While plastic bags may provide convenience for customers, there is an overwhelming concern about the effect of them on the health and safety of people, marine life, and the surrounding environment.
Plastic bags and paper bags are used for various purposes such as for shopping, packaging, disposal, carrying and transporting of products from one place to another etc. Millions of people all over the world uses plastic bag as compared to paper bag because they are densely used everywhere (Cave, 2011). The manufacturing process of plastic bags consumes less energy but they have an adverse effect on the environment than paper bags. These plastic bags are generated from the natural resources like petroleum as well as through natural gas because both resources are easily available in a plenty of amount and are cheaper than paper bags. However, paper bags are manufactured by the tree named as “Pulpwood” and they consumes 4 times more energy than plastic bags.
Plastic bags are bad for the environment. They are made from dangerous chemicals, pollute our oceans and land, and are costly to clean up. Banning or taxing them could lead to a long term solution to the plastic waste problem. Most plastic bags are made from polycyclic aromatic hydrocarbons, polypropylene, and polychlorinated biphenyl, which are known hormone disrupting chemicals. They take many years to break down, end up polluting our world, and harming life forms.
Plastic has been use in nearly all over the world. It is used in nearly everything such as part of computer, tables, toys and more. For years it develop its usefulness, from something that people wants into things that people need. It will evolve and it will not stop helping our lives. They are strong, durable, some are clear, some are clean and also helpful.
Evidently, plastic surgery has affected many lives, which brings one of the reason plastic surgery continues expanding—the power of words. Upon hearing or seeing different individuals change their life with the power of plastic surgery, human nature arises and verges to copy until the chain of plastic surgery spreads throughout the world. Another cause of its recognition is the world’s advancement in technology. Upon the progress of gadgets and machineries, people are more guaranteed of a satisfaction after the procedure. Also, it made the treatment more affordable.
It is a material that is designed to be strong, cheap, durable and easy to manufacture. However, where there is usage, there is disposal. Every moment on the earth, massive of plastic is produced and also the waste, people may think once they throw away their plastic products, they are disappeared forever, however, the truth is, “over 80 percent of ocean plastic leaks from land-based sources, even if people don’t live near the sea, chances are the plastic garbage has found its way o the sea” (A Plastic Ocean). Once the plastic has entered the ecosphere, they will be caught by the rainwater, picked up by the stream and river, and finally get into the ocean. People should be aware that, our ocean is heavily polluted by plastic from its surface to its bottom, just as Mike deGruy said in A Plastic Ocean after he finished his deep-sea exploration and saw a plenty of
1.0 Introduction Plastics have proven to be essential to society. The versatile nature of plastics makes it one of the most sought-after material. According to The New York Times (2011), close to 300 million tons of plastic is being produced annually. Furthermore, an article by The World Counts (2014) suggests that only 1 to 3% of the plastic produced is recycled globally. Even more worrying is the fact that plastic is a non-biodegradable material which means that it is extremely difficult to dispose of, thus resulting in a surplus of unwanted plastic that has no means of proper disposal.
