Where does our poo go? 我们的便便去向何方？ "

Ever wondered what happens to your poo once it drops into the toilet?

你是否有好奇过便便掉入厕所之后会怎样？

Perhaps you’re lucky enough to live in a country where you don’t have to think about it. Because for billions of people, there is no safe toilet or sanitation service to take away the waste, allowing poo to get out into the open air where it’s spread by flies, making people seriously ill.

也许你足够幸运生活在一个不需要思考这个问题的国家。因为对于上亿人口来说，没有安全的厕所或卫生设施处理这些排泄物，导致粪便暴露在空气中，通过苍蝇传播，造成人们严重生病。

And even where there is some sanitation infrastructure, pipework can break or raw sewage can be emptied into the environment, contaminating farmland and water sources.

甚至就算有一些卫生基础设置，管道损坏会将未经处理的污水排放到环境中，污染农田和水源。

Dealing with our poo properly is not only about averting danger, it’s also about seizing an opportunity.

妥善处理我们的粪便不仅要避免危险，还要抓住时机。

By 2030, the Sustainable Development Goals aim to reach everyone with sanitation, and halve the proportion of untreated wastewater and increase recycling and safe reuse.

到2030年，可持续发展目标旨在满足每个人都享有卫生条件，将未经处理的污水排放减半，以及增加回收和安全再利用。

To achieve those goals, we need everyone’s poo to take a 4-step journey.

要完成这些目标，需要将每个人的粪便经过4个步骤的处理。
