1. Plastics can come under the categories of thermoplastic and thermosetting plastics. Both have very different properties. Most modern plastics are manufactured from chemicals obtained from crude oil. Plastic can be shaped or formed using a variety of industrial processes such as vacuum forming, injection moulding, blow moulding, line bending, compression moulding and extrusion. There are also a number of finishing techniques that can be used to give a particular colour or texture to a plastic. 2. Seven reasons why we use plastics. They are light in weight. They are tough and durable They are strong. They can be shaped easily, quickly and cheaply. 3. Many types and forms of plastic pollution exist. Plastic pollution can affect lands, waterways and oceans. Plastic reduction efforts have occurred in some areas in attempts to reduce plastic consumption and promote plastic recycling. The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans. 4. Buy products with less Plastic packaging and tell store Personnel why you are doing so. Shoppers should use their own bags or recycled paper bags. Support recycling schemes and promote support for one in your local area. Practice and promote proper disposal of plastics in your home and at the beach. Always remember that litter generates litter. Never dispose of plastics in the sewage system. In the street never throw plastic or other litter out of your car or drop it on the pavement or in the gutter. Set an example to others and encourage them to help.
