we should use plastic packaging because:

• plastic helps store food hygienically, allowing food to remain fresh and so it avoids food waste
• plastic can be reused and recycled
• alternatives to plastic packaging are not very effective.

we should not use plastic packaging because:

• plastic is harmful to wildlife
• most plastic is made from non-renewable sources
• plastic packaging contain harmful chemicals
• plastic remains with us for a long time (plastic bags are not truly degradable and their small fragments pollute the environment)
