DISADVANTAGESOF SYNTHETIC FIBRES
Synthetic fibres melt on heating. If a person is wearing clothes made of synthetic fibres and his clothes catch fire accidently, then the synthetic fibres of clothes melt and stick to the body of the person causing severe burns.
2. Clothes made of synthetic fibres are not suitable for wearing during hot summer weather. Clothes made of synthetic fibres do not have sufficient pores for the sweat to come out, evaporate and cool our body. Due to this, clothes made of synthetic fibres make us feel hot and uncomfortable during summer.
DISADVANTAGES OF USING PLASTICS
1. Plastic is non-biodegradable. So, the articles made of plastics do not rot when they are thrown away after use. The waste plastic articles keep on acculumating in the surroundings and pollute the environment.
2. The waste particles thrown here and there carelessly get into dirty water drains and sewers, and block them. This makes the dirty drain water to flow over the streets and roads causing unhygienic conditions.
3. Sometimes the animals like cows eat up the used polythene bags or plastic wrappers aolngwith the left-over food and vegetable wastes thrown on garbage dumps. The plastic wastes can choke the respiratory system of these animals or form a plastic lining in their stomach. This can cause the death of these animals.
4. When the plastic waste materials are burnt, they produce poisonous gases which pollute the air.
