THE MATERIAL OF 1000 USES

 

Leo Hendrik Baekeland HonFRSE was a Belgian chemist. Educated in Belgium and Germany, he spent most of his career in the United States. He is best known for the inventions of Velox photographic paper in 1893 and Bakelite in 1907. 

Bakelite: 

A hard, infusible, and chemically resistant plastic, Bakelite was based on a chemical combination of phenol and formaldehyde. It is a thermosetting plastic. (Thermosetting plastics are materials that become permanently rigid when heated, and cannot be reshaped or melted again.)

IVORY: Ivory is a hard, white material that comes from the teeth and tusks of animals.

D. Answer the Questions

1. What were the uses of plastic in general and what were the benefits of using it?
Uses of plastic:

• Making products like radios, combs, jewelry, packaging, clothing, and hospital equipment.
• Substituting natural materials like ivory.

Benefits of using plastic:

• Durable and long-lasting.
• Lightweight, making it ideal for transportation.
• Unbreakable, safer for items like bottles.
• Keeps food fresh longer.
• Disposable hospital equipment helps prevent infections.

2. What are the environmental advantages of using plastic?

• Vehicles with plastic parts are lighter and consume less fuel.
• Lighter packaging reduces energy consumption during shipping.
• Plastic enables green technology like solar panels.

3. What happens to plastic that is thrown in landfills?

• Plastic does not break down over time.
• Chemicals from plastic seep into groundwater.
• These chemicals eventually end up in the sea, where they are consumed by marine life.

4. How can plastic pollution be curbed?

• Using alternatives like metal, wood, or glass, which are recyclable and easier to dispose of.
• Banning single-use plastics such as shopping bags and straws.
• Adopting less wasteful habits and recycling plastic where possible.

E. Think and Answer

1. How can we balance the advantages of plastic and our responsibility to protect the environment?
We can balance the benefits of plastic by using it selectively, prioritizing essential uses like medical supplies while avoiding single-use plastics. Promoting recycling and choosing alternatives like glass, metal, or wood for non-essential items can help reduce plastic waste.

2. What are some possible methods that might reduce the harmful effects of plastic?

• Encouraging the use of biodegradable plastics.
• Increasing recycling programs and facilities.
• Educating people about the harmful effects of plastic pollution.
• Implementing stricter regulations on plastic production and disposal.
• Supporting innovations in sustainable materials.

3. Does the text support a complete ban on plastic? Why or why not?
No, the text does not support a complete ban on plastic. While it highlights the harmful effects of plastic, it acknowledges the importance of plastics in essential applications like medical supplies. The problem lies in how we use and dispose of plastic, not in the material itself. The text advocates for responsible use and reducing wasteful habits rather than an outright ban.

EXTRA QUESTIONS

1. What is the experiment that Susan Freinkel does regarding plastic?
Susan Freinkel did a simple experiment. She wrote down every object she touched during the first hour after waking up. She also noted what each object was made of. Out of 298 objects, 196 were made of plastic. This surprised her and showed how common plastic is in daily life. This experiment inspired her to research and write her book about plastic.

2. Write down some of the advantages of plastic.
Plastic has many advantages. It is light, strong, and unbreakable. Plastic bottles do not break like glass. Plastic packets keep food fresh for a longer time. In hospitals, plastic gloves and tools prevent infections because they are disposable. Plastic parts in vehicles reduce weight and save fuel. It is also useful in green technology like solar panels.

3. What does Bakelite's inventor say about plastic?
Bakelite was the first type of plastic, invented in 1907 by Leo Baekeland. He wrote in his journal that his invention would prove important in the future. He believed plastic would be very useful. Later, his words became true because Bakelite was used to make radios, combs, and jewellery, and it became known as the “material of a thousand uses.”

4. What are the reasons for replacing materials with plastic?
Plastic replaced natural materials because some of them, like ivory, came from endangered animals. During World War II, natural resources were limited, so plastic was used instead. Plastic was cheaper, lighter, and easier to produce. It could be shaped into many forms and used for packaging, clothing, and household items, making it a popular substitute.

5. How does plastic add to the pollution of the environment?
Plastic causes pollution because it does not break down easily. Most plastic is not recycled and is thrown away. It collects in landfills and oceans. Harmful chemicals from plastic enter water and affect marine life. Many sea animals eat plastic and get harmed. Over time, plastic pollution spreads across oceans and even enters the human food chain.

6. Does plastic prove that human inventions turn out to be dangerous for humans themselves?
Plastic shows that human inventions can be both helpful and harmful. It is not plastic itself that is dangerous, but the way people use and dispose of it. Useful items like hospital supplies save lives, but single-use plastic like bags and straws create waste. So, inventions are not bad, but careless use can make them harmful.

7. How do man-made inventions affect the environment? Discuss with respect to plastic.
Man-made inventions like plastic can affect the environment in positive and negative ways. Plastic helps in health care, transport, and technology. However, its overuse and poor disposal cause pollution. It does not decompose and harms animals and oceans. If people reduce, reuse, and recycle plastic properly, they can enjoy its benefits without damaging the environment.

8. What are the environmental advantages of plastic?
Plastic also has some environmental advantages. It is lighter than materials like glass and metal, so transporting plastic products uses less fuel and energy. This helps reduce carbon emissions. Plastic packaging keeps food fresh for a longer time, which reduces food waste. Vehicles made with plastic parts are lighter and consume less fuel. Plastic is also used in green technologies like solar panels and wind turbines, which help produce clean energy and protect the environment.

9. What happens to plastic that is thrown in landfills?

Plastic thrown into landfills does not break down easily because it is non-biodegradable. It can remain there for hundreds of years without decomposing. Over time, sunlight and heat may cause it to break into tiny pieces called microplastics, but it never fully disappears. Harmful chemicals from plastic can slowly leak into the soil and mix with groundwater. This polluted water may reach rivers and seas, harming plants, animals, and even humans through the food chain.
