 PLASTICS

There is a great diversity (variety) of materials. Metals, glass and ceramics are just a few examples. But, I will be concentrating on only one material. It is called plastic.

Plastic has many usefulness. It is used to make many, many things. Examples are the plastic bags you get when you go shopping and the raincoat you wear when it is raining. Sometimes, plastic is made to look and even feel like metal, glass and wood. Examples are the windows you have (for only some homes) and some Video Compact Discs (VCD).

Plastic is man-made (meaning made from human beings) and are several ways to make it. One way (which I watched from television) is:

1.)         Boil milk till bubbles form,

2.)         Then add some vinegar.

3.)         The mixture would separate the solid (mixture) from the liquid (water).

4.)         Using a sieve, separate the mixture.

5.)         Leave the mixture to dry.

6.)     After the mixture dries, the mixture becomes plastic and is ready to be made into any shape.

Although plastic has many advantages, it has a very serious disadvantage unknown by many people.

The disadvantage is: plastic pollutes the environment leading to rapid global warming. If global warming becomes severe, the organisms on Earth might not be able to live on Earth anymore.

A way to reduce the usage of plastics:

Bring your own environmental-free bag when shopping.

So, we should not be using so much plastic objects. We could change into using metal, glass or wooden objects. So, from today onwards, we should reduce using plastic and make the world a better place!
