Polymers


	Polymers
	Advantages Cheap to make Many uses because of their different properties. Provide jobs in firms which make the polymer and the product. Some polymers can be recycled, melted down and made into something else which saves valuable natural resources. If polymers are used instead of wood, fewer trees will have to be cut down.	Disadvantages People do not like to live near polymer-producing industrial works. Some people think plastic products look cheap compared with natural materials. Made from oil, a non-renewable resource. Most plastics are not biodegradable so there is a problem of how to get rid of them. Landfill sites are ugly. Give off toxic fumes when they burn. Sorting types of polymers for recycling can be expensive.
