Question

which issue is a limitation of using synthetic polymers? check all that apply.
as trash, synthetic polymers are not biodegradable.
landfills can easily fill up with synthetic polymers.
plastics can be made into many different products.
recycling synthetic polymers is costly.
synthetic polymer production is not expensive.
synthetic polymers can be produced in big quantities.

Explanation:

• As trash, synthetic polymers are not biodegradable: This is a limitation as non - biodegradable waste persists in the environment for a long time, causing pollution.
• Landfills can easily fill up with synthetic polymers: Since they don't degrade easily, they take up space in landfills, which is a problem for waste management.
• Recycling synthetic polymers is costly: High recycling costs can be a barrier to reducing their environmental impact.

The statement "Plastics can be made into many different products" is an advantage, not a limitation. "Synthetic polymer production is not expensive" is also an advantage. "Synthetic polymers can be produced in big quantities" is more of a production - related aspect (not a limitation in the context of environmental or waste - related issues).

Answer:

As trash, synthetic polymers are not biodegradable; Landfills can easily fill up with synthetic polymers; Recycling synthetic polymers is costly.
