Plastic



A brief history of plastic

In the 1920s, researchers first commercially developed polystyrene, a spongy plastic used in insulation. Soon after came polyvinyl chloride, or vinyl, which was flexible yet hardy. And in the 1930s nylon took center stage a polymer designed to mimic silk but with many times its strength. Starting in 1933, polyethylene became one of the most versatile plastics,  still used today to make everything from grocery bags to shampoo bottles, to bulletproof vests. New manufacturing technologies accompanied this explosion of materials. The invention of a technique called injection molding made it possible to insert melted plastics into molds of any shape, where they would rapidly harden. This created possibilities for products in new varieties and shapes and a way to inexpensively and rapidly produce plastics at scale.


 Scientists hoped this economical new material would make items that once had been unaffordable accessible to more people. Instead, plastics were used in World War Two. During the war, plastic production in the United States quadrupled. Soldiers wore everything made of plastic for example raincoats etc. Pilots sat in cockpits made of plastic and they used parachutes made of plastic.  plastic attracted many plastic manufacturing companies at that time so plastics began to replace every kind of material like wood, glass, and fabric in furniture, clothing, etc. Versatile plastics were designed to keep food and many other products fresh for longer. Suddenly, there were plastic garbage bags, stretchy plastic wrap, squeezable plastic bottles, takeaway cartons, and plastic containers for fruit, vegetables, and meat. Within just a few decades, plastic gained a lot of fame and this century got started to be known as the “plastics century. Plastics century brought convenience and it was affordable but it also created staggering environmental problems. Plastics are made of nonrenewable resources which are very harmful to the environment.


Pros

Plastic can be used for a long period. its various products are very useful for household uses.it is very durable and cannot break easily. It is water-resistant and strong and many kitchen items like containers, bowls, and spoons are made from plastic. It can be recycled and take very less money

Cons

It does not degrade easily many animals by mistake consume plastic which has a bad effect on their health  Flammable This is definitely an advantage in that they can be melted down, however, smoldering plastics can release toxic fumes into the environment.   Plastics are durable, which means that they will stay last a long time. Plastics in the landfill will stay there for years. Chemicals in plastics may be harmful to health. They can also release toxins into our food, water, and environment. There is a lot of plastic in the ocean from which many thousands of animals from small fish to big fish die by eating or getting caught in plastic.

 


As you can see plastic brings us no good in the future. It is time for us the future generation to change this not only for us but for generations to come.

Era Of Tecnhology

  As we go through the 21st century, some common questions arise from the development of technology: who will be responsible for its negative effects? if there is a possibility of future changes that might affect society or even change our way of life? and when will they happen? as it has been said earlier “Technology is the new black swan” because in my opinion technologies have many hidden meanings and can create lots of opportunities in terms of education, research, entertainment…etc. In addition to these good and bad things, it can also help people to gain knowledge and skills like communication, health care, farming, etc. The Internet alone only creates opportunities to communicate with those around us but also creates threats if we do not take care of our privacy and security, so we must protect our data from online threats, misuse, abuse, or threats by others. To do this, we need to think about what can be used and what cannot, and how can be easily detected and prevented. T...

Pakistan growing economy

Image
As you may have noticed, two key aspects of your life determine how well or poorly in terms of business you will do – the economy. On the one hand, it is vital to know your economic metrics. On the other hand, it can be beneficial to follow this knowledge and better understand where you stand financially. That’s why we decided to write a separate article here – because it is our responsibility as humans to provide us with facts about living in Pakistan that can help us make informed decisions in whatever domain of our lives we want to explore positively. Graph of Pakistan's GDP annual growth rate  GDP Our country has a GDP growth rate of 7%, which means that the country’s gross domestic product (GDP) grew by 7.2 % in 2018. This was due largely to increased foreign direct investment and improved agriculture productivity, which increased GDP’s exports by 35.3% in 2016-17. In addition, as a result of increasing oil prices, net petroleum exports rose by 14.9% from $13 billion to $14.6 ...

Pollution

  What is pollution? It's the act of adding something to the environment that no human being has ever seen before. It is the introduction of substances into the environment that has a damaging effect on living things there are two types of pollution human and natural. human pollution affects at a very large extent while natural to a small extent. Pollutants are harmful substances that damage living things and the environment and lead to pollution. Air Pollution The most common kind of pollution is called air pollution as it happens when an object, such as a car or airplane, is put into the atmosphere and pollutes it. But there are other types of pollution. Some things are natural while others are man-made. A typical example of pollution that is man-made is coal mining. Coal miners use burning coal to create electricity for their homes and to sell electricity to homes. They have to burn large amounts of coal at high temperatures to produce energy. As more and more coal gets burned...
