When plastic was first made around 1870, people thought it was amazing and called it an “environmental hero”! It was light, long-lasting and cheap. It quickly replaced(取代) wood and other natural materials. Not surprisingly, plastic has now filled our lives too. We can find it in bags, toothbrushes, mobile phones, houses... It certainly has thousands of uses.
But slowly and silently, plastic has shown its dark side. Plastic waste has become a danger to sea animals. Some animals like whales eat it by mistake and die. The “hero” of the past now kills over 100,000 sea animals each year. By 2050, there could be even more plastic in the sea than fish.
Plastic also causes problems on land. Birds’ wings get tied in plastic lines. Bears’ heads get stuck in plastic bins. Even humans are eating plastic waste! On average, we eat five grams of plastic a week. That’s a whole bank card! Tiny pieces of plastic are found in the air. There is even plastic “snow” at the South and North Poles(南极和北极). On “Earth Plastic”, nowhere is safe from plastic.
Moreover, getting free of plastic waste isn’t easy. It may take thousands of years to break down. So hiding the waste in the ground doesn’t help. Burning it also produces thick smoke and causes air pollution.
Plastic is not just causing an environmental problem. It means life and death for humans and for the future of the earth. Everyone knows there is only one earth. So let’s live without plastic!
