Consider the following:

1. Cigarette butts
2. Eyeglass lenses
3. Car tyres

How many of them contain plastic?

1. Only one
2. Only two
3. All the three
4. None

Explanation

Cigarette butts contain plastic

• Cigarette butts do contain plastic. The filter of a cigarette is primarily made of cellulose acetate, a type of plastic. Cigarette butts are actually the most abundant form of plastic waste in the world, with about 4.5 trillion individual butts polluting our global environment.

Eyeglass lenses contain plastic

• Most modern eyeglass lenses are made from plastic, not glass. Common materials include polycarbonate and CR-39 plastic. These are lightweight, impact-resistant, and cheaper than glass.

Car tyres contain plastic

• Car tyres are not pure rubber; they contain synthetic polymers (plastics). They are made from a blend of natural and synthetic rubber (such as styrene-butadiene rubber, a synthetic polymer). They also contain nylon and polyester fibres, which are also plastic-based materials.
