The plan had been made to create a beautiful nature park with a large man-made lake on the outer parts of the city of Zhengzhou, the capital of Henan Province. However, thanks to a terrible trick played by nature, what the officials have ended up with, is a natural sandy mess!

The government wanted to create a beautiful place where people of this busy industrial city could come to relax. But things did not quite turn out that way---shortly after digging up thousands of tons of sand, the underground water dried up. As a result, the dry sand has changed into a Sahara-like desert. While official reports show that the sand is piled up to 10 meters high, some people say that it is ten times more or about a 100-feet high in certain areas.

If that is not bad enough, the sand hills that now spread across an area the size of four football fields, have influenced the environment. What’s worse is that on windy days, the dry sand moves into the city center, making it almost impossible to drive and forcing people to wear face masks and protective eyewear to prevent the sand from getting into their eyes, nose, and mouth.

In an act of trying to keep the sand and provide the illusion(幻想) of green fields, the officials have even tried covering it with a green plastic netting. However, that has not done much to improve the terrible situation!

As you can imagine, many of Zhengzhou’s residents are upset by the disaster. They think that desert wasteland that looks nothing like the green landscape they were promised, has resulted in polluting their pleasant city environment. Some think it is even stopping businessmen from coming to the city.

One of the problems damaging our planet is the number of things we throw away. Rubbish of all kinds is piling up in landfill and polluting our rivers and oceans. A more recent addition to the list of things we chuck away is e-waste — electronic items that are broken and not recycled. Now solutions are being found to give this stuff a new life.

Many millions of tonnes of televisions, phones, and other electronic equipment are discarded each year, partly because it’s cheaper to replace them than fix them, but also because we lack the skills to repair them. A UN report claims the 50 million tonnes of e-waste generated every year will more than double to 110 million tonnes by 2050, making it the fastest growing waste stream in the world.

However, there’s a growing trend for repair events and clubs which could be part of a solution to the growing amount of electrical and electronic junk. The BBC visited a Restart Project in London, which is one of many founded around the world. One of its volunteers, Francesco Calo, said that “this project allows you to reduce waste, extend the life of objects, and it helps people who cannot afford to get rid of items that have developed a fault.”

As many electrical items contain valuable metals, another idea is e-waste mining. An experiment at the University of New South Wales involves extracting (提取) these materials from electronic gadgets. It’s thought that doing this could be more profitable than traditional mining. With phones typically containing as many as 60 element, this could be part of the solution to our appetite for new technology.

These projects make total sense — collections of e-waste for recycling are “stagnating (停滞不前) or even decreasing” according to Ruediger Kuehr, of the United Nations University And in countries where there is no legislation, much of it just gets dumped. However, the European Union, for example, is trying to tackle the problem by insisting manufacturers have to make appliances longer-lasting and will have to supply spare parts for machines for up to 10 years.

Indonesia

What Indonesians commonly do is put their trash in their personal garbage area which is usually located at the front of their houses, right at the side of the street. Put trash there, and the garbage collectors with their big garbage trucks will pick it up.

Germany

The country has a quite detailed way of sorting its wast — down to the color of the glass waste and the type of paper that can be put inside the garbage bin. Some common public garbage bins are available in the German apartment/housing area：

Some items don’t belong in your housing area’s public garbage bins. Items like used batteries, electronics, unused paints, and light bulbs must be returned to special locations so they can be recycled. Other items such as clothes, oversized trash and furniture are advised to be sold or donated.

South Korea

Here are the types of garbage bin provided in South Korea：

Because the food waste bin is reserved for anything that can be eaten by animals, eggshells, crustacean shells and bones are fairly forbidden from it. You have to separate the bones from your meat waste, put the meat waste in the food waste bin and put the rest of the bones in the general waste bin.
