**问题：以下哪种行为最有助于减少塑料污染？**

A. 经常购买一次性塑料制品并正确分类回收  
B. 使用可重复使用的购物袋代替塑料袋  
C. 将塑料垃圾丢入垃圾填埋场而不是大海  
D. 经常更换塑料制品以保持环保

**正确答案：** B. 使用可重复使用的购物袋代替塑料袋

**解析：**  
减少塑料污染的关键在于减少塑料使用量，而使用可重复利用的购物袋能够有效减少对一次性塑料袋的依赖。这种行为不仅减少了塑料制品的生产需求，也降低了自然环境中塑料垃圾的堆积量。同时，虽然分类回收（选项A）和正确处理废物（选项C）是重要的环保措施，但它们对塑料污染本身的效果有限。选项D则并不符合环保理念，因为频繁更换塑料制品会进一步加剧塑料浪费。
