　　[2019·石家庄二模]Though the harmful effects of plastic on wildlife and human health are well­documented, this material is hard to avoid. Nearly everything we touch, from grocery bags to drink bottles, to food packaging, contains plastic. Now, Amsterdam's Ekoplaza supermarket is making it a little easier for consumers to reduce consumption of single­use plastic bags and containers, which are blocking our landfills at alarming rates, with a special plastic­free aisle (通道). Believed to be the world's first, the aisle has 700 products on sale including rice, beans, yogurt, chocolate milk, cereal, snacks and meat.

　　While items still require packaging, everything is housed inside reusable or recyclable containers made of glass, metal or cardboard. The unique idea was given to the grocery­chain officials by UK­based environmental group A Plastic Planet, which takes the lead to advocate for at least one plastic­free aisle in supermarkets around the globe. The non­profit has even created a signature "plastic­free" mark to help consumers identify eco­friendly packaging. "This is a consumer­led campaign，" said a group co­founder Sian Sutherland. "We're a grass­roots organization. So obviously we're working with industry and the government, but most importantly, we represent the public."

　　Ekoplaza, which plans to roll out the plastic­free aisles across its 74 stores by the end of the year, is not the only company trying to reduce plastic waste. In Berlin, the Original Unverpackt grocery store has been trying to change customer habits since 2014 by selling everything, from grain to produce and even soaps without plastic packaging. The supermarket, which requires customers to bring their own reusable containers, even sells chewable toothpaste that needs no tubes.

　　Though it is encouraging to see companies trying to make a difference, for real change to happen, consumers have to avoid products encased in plastics, even if it means giving up their favorite food or drink. As Sutherland put it, "Plastic food and drink packaging remains useful and yet a destructive presence on the earth for centuries afterwards."
