...IMPORTANCE OF PLASTIC:- Plastics are a subset of materials known as Polymers. These are composed of large molecules formed by joining many smaller molecules together (monomers). Other kinds of polymers are fibres, elastomers, surface coating and biopolymers, such as cellulose, proteins and nucleic acids. Plastics owe their name to their ability to be shaped to form articles of practical value by various conversion and forming processes. These are some peculiar properties of plastics materials, which make them unique so that products can literally be tailor-made out of these materials. In fact, plastics have permeated every facet of human life viz. agriculture and water consumption, buiilding construction, communication, small and bulk packaging, education, medicine, transportation, defence, consumer durables to name a few. One of the reasons for great popularity of plastics is due to tremendous range of properties exhibited by them because of their ease of processing. Hence, the demand for plastics has been increasing in modern living. Since last six decades, the Plastic Industry has grown world wide with present consumption of more than 130 MMTPA. The Polymer/Plastic growth worldwide has been steady around 6% per annum which is much higher than the GDP growth rate of 3.3%. The higher growth sectors or demand drivers for plastic...
Plastic is one of the most used material these days. It is being used in almost every industry. But along with its advantages, there are lot of disadvantages of plastic too. Let’s take a look at the positive and negative effects of plastic.
Increasing usage of plastic
In our daily life, plastic made a considerable impact and we are heavily dependent on plastic. Starting from daily usage utensils to decorative items all are coming in plastic. The usage of plastic is increasing day by day and researchers are also trying to develop more durable, less weight, strong plastic to meet today’s needs. The usage of plastic is increasing exponentially from the last century. Records showed that the amount of plastic made in the first 10 years of 21stcentury is equal to the amount of plastic made in the whole 20thcentury. Generally, Plastic is of two types i.e. high quality plastic and low quality plastic. High quality plastic is very strong and is generally used for making products like cabins, mobile and laptop cases etc. Low quality plastic is generally weak and is used for making utensils, vessels etc.
Positive impact of plastic
There are several advantages with plastic which can’t be compared with others. Plastic is highly durable material and it lasts longer. Another positive thing about plastic is its ease in converting to required shape. The weight of the plastic is very less and it is almost as strong as metals. You can convert plastic into the shape you required and they look equally beautiful like glass or other expensive materials. Unlike glass which has to be handled carefully, you can roughly use plastic materials. One more advantage of plastic is it is recyclable. The wear and tear of plastic parts is very less when compared to other materials available.
Negative impact of plastic
The modern lifestyle is focused on people who are always on the move. For this reason, food is available in cans, plastic containers, and other materials. The more people make use of these items, the higher the rate at which they accumulate the amount of garbage on the planet. Among the most stubborn forms of garbage are plastics. They do not rot as naturally as their other counterparts. Also, when burned up, they emit fumes which contain very harmful chemicals. Here, we focus on the ways plastics affect the planet we call home.
There are some negative things about plastic which has to be considered equally like advantages. Plastic items can’t tolerate high temperatures and releases harmful gases (at high temp.) which cause pollution. Plastic is not easily disposable and it will take thousands of years to completely dispose in soil. This result in other harmful things like blockage of water (resulting floods), death of animals, birds because of eating plastic etc. which are serious concerns of several environmental activists. Even the process of making plastic by industries releases heavy amounts of carbon dioxide.
There are so many advantages with plastic and it has to be used carefully and within the limitations to protect environment. Plastic is recyclable and hence instead of disposing it, everybody must take initiative to recycle so that the effect of plastic on environment will be less. Recycling of plastic not only helps environment but also gives you money. Several governments are making regulatory laws to regulate the use of plastic and several NGO’s from all over the world are trying to create awareness among people about plastic. Presently plastic accounts 10% of waste which is a serious concern of several environmental activists. It has to be reduced substantially for better future.
Sources of Plastic Pollutants
Each day, we release plastics to the environment in ways we do not expect.
Trash is everyday materials such as plastic bags,water bottles, milk packets, and electronic parts and so on. High impact plastics find their way to the environment in many different ways including when you ‘innocently’ through a water bottle to the dustbin in town. You may even have an item such as cloth but not recognize the fact that the buttons are made of plastic.
It may not be a surprise to recognize the fact that plastics are among the most used material on the planet. The fact that they are among the cheapest and most commonly available materials makes them among the most dangerous pollutants on the planet. The harmful effects of plastics may include the introduction of inorganic materials in the soil and harmful gasses in the atmosphere when it is burned, but plastics do more than that as they have compounds that may cause diseases to people and animals. When they find their way into waterways and other areas, they may harm the users of the water including marine life.
Fishing activities require a lot of equipment such as nets which are mostly made of plastics. When the nets break down, they are often left to stay in the water. Also, the fact that the nets stay in water means that they emit toxins at will. High impact plastics are the worst of them all since their level of harm to the environment is higher than the other types of plastics. The harmful effects of plastics on the environment will depend on the materials that went into their making.
Impact plastics are those that continue to release toxins into the environment even after their use. High impact plastics are those whose level of chemicals released is higher than the others. When plastics are used and either disposed of or recycled, they will still release their toxic substances to the environment. People make the mistake of thinking that recycling is the solution to the issue of pollution from plastics when it is not. Even the recycling process for plastics is very costly and will lead to the release of some of the gasses that are released when the plastics are burned.
Pollution from Plastics affects the Natural Food Chain
Among the harmful effects of plastics is that they affect the natural order of feeding. They affect from the large animals to the microscopic plankton which is the main type of food eaten by fish and other aquatic lifeforms. Plastics will affect every part of the food chain to the extent that even the large animals in the food chain will be affected. They may be directly affected by feeding on plastic toxins or indirectly by lacking the food to eat after the plastics have killed the animals down in the chain.
Plastics Pollute sources of Water
A large part of the water we drink is transported through the ground through pipes and other methods. The plastics in the dumpsite will mix, resulting in high impact plastic and seep into the ground and into most sources of ground water. The harmful effects of plastics can be passed through the ground to the body through various ways like the water explained here. For most people, ground water is assumed to be safe for drinking when the reality is far from that. Unless it has been treated and approved for human consumption, do not attempt to drink it as you will be taking in lots of poisons.
Air and Land Pollution
Plastics have chemicals that can be transported through water and air to various locations that they can harm the people who come into contact with them. For all one may know, the plastic items in the home may not harm them during their use, but once they are burned or disposed of, they will have such a big impact on the environment that they have been declared among the most impactful of pollutants on the planet. One needs to focus on their impact on land, water, and the air to avoid their polluting effect.
Finally, plastic is like a double edged sword and we must use it carefully to avoid future complications and environmental problems. Even methods suggested by plastic companies like burying deep in the earth will also have its own implications on environment. So plastic companies and plastic users have to use it cautiously. Plastic must be used according to our needs but not for our luxuries.
With the high number of plastics on the planet and in everyday use, there are measures put in place to stop their pollution on the environment. First of all is the issue of recycling. Recycling will ensure that the plastics do not find their way to the ground or sources of water to impact it in negative ways. It is the responsibility of everyone to take the plastic to the right locations for recycling or other use that will not affect the people around the area. This is the best way of dealing with the plastics.
