on the back of something

That's something to strive for. But even if we can't reach that point, most of us could cut back on the nagging.

这种境界是我们奋斗的目标，但是尽管我们可能达不到那个境界，我们中的大多数人仍能减少抱怨。

We want to reduce and repair environmental damage, cut back on the production and consumption of resource-intensive food, increase efficiency and do something about waste.

我们想减少环境破坏，我们想修复破坏的环境，减少资源密集型食物的生产和消费，提高效能，处理浪费。

Then developers tie it together on the back end and the service consumers have something to write against on the front end and it all kind of meets in the middle.

然后，开发者在后台跟它配合，服务消费者在前台根据它书写，大家最后在中间汇聚在一起。
