woolworths Australia in home delivery problem

in class we are talking about woolworths Australia in home delivery problem, Woolworths has made a commercial saying that how delivery groceries will be delivered in eco bags: environmental bags but the truth is that the groceries will be delivered to customers and bagged twice over in plastic bags. i want the writer to write about the cons and pros:(negative and positive about if Woolworths keep delivering in plastic bags and the negative and positive if they do as they said deliver groceries in environmental bags. and what are the alternative for example what Coles or international companies like Woolworths are doing? I need the writer to write about just on the delivery process.
