Overcoming the Problem of Waste

Many large cities are anything but beautiful. Streets are littered with trash. In this trash, however, there is still something that can be useful.

If people want to solve the problem of waste, there is no time to be lost. They must work out ways of making use of good things which are just thrown away as waste.

When a car gets too old, it may not run any more. But the metal that the car was made of is still good. It can be put to use again.

When a bottle is empty, it goes out in the trash. But bottle glass can be ground into sand and used to pave¹ streets.

Garbage from food can be changed into fertilizer². But first you have to fish out all the glass and metal.

Garbage can also be a good source³ for making building blocks, which are then covered with concrete⁴. Now, more and more machines are designed for this purpose. Some day, people will watch films in a magnificent⁵ cinema which has been built out of garbage. Future buildings, roads, and cities maybe made from garbage. But so far, building beautiful cities out of garbage is only a dream.      

现在许多大城市不堪入目。街道上满是被乱丢乱放的垃圾，而在这些垃圾里，仍有一些有用的东西。     

如果人们想解决废物问题，已经是时候了。他们必须研究出一些垃级再利用的方法。     

如不能再行驶的旧汽车，车上的金属还是好的，这些金属可以重新利用。     

还有废弃在垃圾里的空瓶子，玻璃瓶可以被磨成沙用来铺路。

食物垃圾可以变成肥料，但首先你得检出所有的玻璃和金属。
