【正确答案】Plastic wastes are becoming a serious environmental problem. Plastic products have brought much convenience to people as well as disastrous problems to our environment. It's well-known that a vast majority of plastic products do not degrade in a landfill or a compost-like environment, nor can they be recycled. So how to dispose of plastic wastes becomes a big problem. What's more, plastics are the cause of many deaths of animals and fish because they mistake them for food. So we must find a solution to plastic pollution before our earth is covered with plastics.
