Dear SirGreenrock President, Judith Lansburg, has the right idea on preventing the build up of plastic bags that is neither biodegradable or essential in today’s modern world. Humans have to make very conscious and consistent efforts to be more responsible for what we leave behind on planet earth as our ecosystems are all interconnected, i.e., marine life, wild life, plant life, human life, etc,Ms Linsburg your concept is brilliant, it just needs to be tweeted. Rather than asking for a tax from consumers, why not ask retailers to give back 10c or 5c on each purchase made when each customer refuses to take a bag? So, rather than ask the consumer to pay for a bag/tax, ask the retailer to give each consumer a rebate of 10c or 5c on their bill for NOT taking a bag.Next, ask each consumer to use cloth not plastic bags that retailers can sell to each consumer for 25c per bag. That ONE time payment means that consumers use biodegradable bag for their shopping.With supermarkets, ask consumers to buy and/or bring in biodegradable for their groceries, and supermarkets will refund 5c on each bag used by the consumer for their groceries. And, consumers can buy biodegradable cloth bags from their supermarkets, again a ONE off purchase. Cloth bags are washable and reusable without harming the environment.And your charity has the opportunity to make some money here, design a stylist biodegradable bag with your charity’s logo to champion this cause. Promote it, sell it and educate the consumer on your cause. These bags will be used over and over again by each consumer.Remember, rather than ask the consumer to pay, give them a refund (reduce their bill by how many bags they refuse — 5 bags refused multiplied by 5c per bag = 25c off their final bill).The amount may sound very insignificant, but it adds up to quite a large savings for supermarkets, who will reduce their reliance on plastic bags whilst selling biodegradable bags to consumers that reduce the impact of plastic bags in our environment.Valirie Marcia AkinstallLondon, England
