Answers
Answer:
a) A plastic bag, poly bag, or pouch is a type of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals, and waste. It is a common form of packaging.
b)Plastics are durable, lightweight and inexpensive materials, and they can be widely applied to mold into various products. Every year, more than 100 million tons of plastics are manufactured across the globe. Around 200 billion pounds of new plastic materials is thermoformed, foamed, laminated and extruded into millions of packages and products. Consequently, it is of great importance to reuse and recycle plastics.
harmful effects of plastic bag:
Littering of plastics in open spaces creates unhygienic conditions, as it acts as a breeding ground for insects and mosquitoes that cause diseases like malaria and dengue.
Plastics do not undergo degradation, thus, stay in the soil for many years, which affects soil fertility and degrades the soil quality.
