我也常常看到在例如小型市场等场所使用塑胶袋的例子，它们大多是超薄塑料袋。执法是唯一的答案。我的经验是，如果没有确实执行有关法律及条例，人们便会视而不见。我会以已使用的塑胶袋盛载垃圾，但是这亦非最佳方法。市场上应该有生物可降解塑胶袋。每一个社区都应设有弃置各种塑料袋的地方，同时循环再造塑胶 (容器)、铝、金属、纸张、其他可再造物质。这都不是难以实现的。然后孩子在学校亦应该接受有关教育，再由他们影响父母，这有助监督社区确实做到循环再造。这都是教育带来的成效。

I've also seen many examples of plastic bag use in places like small markets. In the vast majority of cases, the bags are ultra-thin ones. The only answer is enforcement. My experience is that if laws and regulations aren't enforced then the population will ignore them.
I reuse my plastic bags for garbage but this isn't an ideal situation either. Biodegradable bags for garbage should be on the market.
There should be a place in every community where plastic bags of all kinds can be disposed of, along with the recycling of other garbage such as plastic (containers), aluminum, metal, paper, and other recyclable items. This wouldn't be hard to set into place. We can then educate our children in school who would then help to educate the parents. They can also help to oversee that the recycling is being done properly in their community.
It all comes with education.

限塑令执行起来很困难。限制越多，执行起来越困难，因而不能很好地形成循环经济，使用过的产品和资源能重新成为人类和自然的资源。中国和其他国家应该减少不利于循环经济发展的限制规定，运用简单的市场工具去刺激所有的产品（不仅仅是袋子），使其不再只是成为生态系统中的垃圾。关于如何去做，请看近期我的文章——这是一种着眼于人类未来的简单方法；

Bans are difficult to impose and to enforce. More bans are more difficult, so this is no way to approach a circular economy, where every product and every used resource would return as new resources for people or nature. China and other countries should save bans for items that are incompatible with a circular economy and then use a simple market tool to incentivise all products (not just bags) to not end up as waste in ecosystems. Please see my recent presentation about how to do it - it's not hard and it makes an economy that can work for everyone's future; http://www.wiserearth.org/resource/view/6cde9add775de8a2ead56e6234d9ec7a
