Plastic is made through a process that involves the polymerization of raw materials derived primarily from fossil fuels, such as crude oil and natural gas. These hydrocarbons are refined into monomers, which are small molecules that can bond together to form polymers—a process typically initiated through heat, pressure, or catalysts. The resulting long chains of molecules are then processed into various forms of plastic used in countless applications. One positive effect of plastics is their versatility and durability, making them essential in countless industries like packaging, healthcare, and construction, often leading to cost-effective solutions and improved product longevity. However, a significant negative effect is the environmental impact, as plastics contribute to pollution and waste, with many items taking hundreds of years to decompose, leading to detrimental effects on marine life and ecosystems.
Write a paragraph to answer these questions: How is plastic made? Where do the materials come from? How is a polymer formed? Describe one positive and one negative effect plastics can have on society.

Plastic is made from materials that mainly come from oil and natural gas, which are found deep inside the Earth. First, these materials are processed and turned into tiny molecules called monomers. Then, these monomers are heated and mixed together to form long chains called polymers. These polymers are what make up different types of plastics that we see every day, like bottles, toys, and bags. One good thing about plastics is that they are really strong and can be used for many purposes, like keeping our food safe and helping doctors do their jobs. However, one bad thing about plastic is that it can hurt the environment. Many plastic items take a very long time to break down, and they can end up in oceans and hurt animals that live there.
