Big bag ban

Short description

The EU has recently approved tough new measures to slash the use of plastic bags. New targets will force each country to reduce plastic bag use by 80% before 2019.
In this activity students examine degradable plastic bags as a possible alternative to ordinary plastic bags. They choose questions to ask experts, and come to a reasoned decision in answer to the dilemma question: will degradable plastic bags solve the problems caused by ordinary plastic bags?
