What are plastics? Name four things that are made up of plastics.
- Plastics are a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be moulded into solid objects.
- Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through polymerisation or polycondensation process.
- We need plastics because it is durable and provides protection from contaminants and the elements. It reduces food waste by preserving food and increasing its shelf life. It protects food against pests, microbes and humidity.
- As plastics are not degraded easily, it can remain for a long period of time. Plastic pollution on land poses a threat to the plants and animals – including humans who are based on the land.
- Chlorinated plastic can release harmful chemicals into the surrounding soil, which can then seep into groundwater or other surrounding water sources and also the ecosystem of the world.
Four things made out of plastics are plastic chairs, bottles, plastic bags, straws.
