    It is said that another acre of the world's forest will be destroyed forever. Why is this happening? There are two reasons — land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don't know that in most places the trees won't be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The forest becomes a desert. Then more land will be needed, and more trees will be cut down.
    When the forest is destroyed, it isn't only the trees that are lost — the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger — fish，reptiles, birds, mammals, insects, and shellfish — as well as thousands of plants.
    Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world's population is now six billion. Of course, it's very easy to blame the local people. We don't cut down trees. They do. But the products are bought by people like you and me — wood houses, beds, tables, chairs, paper… Why are the forests being destroyed? Just look around. You are probably using it right now.

Plant scientists consider them as fruit. Most other people think of them as vegetables. Whatever you call tomatoes, there are many different kinds of this popular and healthy food.
There are two groups of the plants. Small tomato plants grow to about one meter. They can be planted rather close together. Some short kinds do not require special care and are often gotten crop by machines. Large tomato plants can grow over two meters tall. They also produce larger fruits.
People who grow only a few plants can place wire cages around each one. The cage can be made of wire fence material. The cage helps the plant grow taller and produce a better crop.
Tomatoes often need extra calcium (Ca), or the fruits may be ruined. Add lime to the soil can solve this problem. Dry lands may also ruin the fruits. Tomatoes need water regularly. The soil should never dry out completely. Dried grass or leaves placed around the plant can help hold water in the soil and stop the growth of unwanted plants.
Tomatoes are native to South America. The tomato is a member of the potato family. The leaves of the plant are poisonous, like the leaves of its relatives. Before the 18th century, people grew tomatoes only as pretty plants. They called the bright red fruit a “love apple”, but would not eat it.

Right in the middle of the town are some long ponds(水池). They are only about half a foot deep. The men of Symi dug out the earth to make the ponds.
Over each pond is a low cover. It is made of glass that you can see through.
At night, sea water is taken into the ponds. The next day, the hot sun shines through the covers. The sun light turns the water into vapor(水蒸气) and the vapor goes up from the ponds. The salt is left behind.
As it goes, the vapor became mist. On the inside of each cover, the little drops of mist run together to make big drops. These drops run down the sides of the cover, filling other ponds with fresh water.
The salt left in the ponds is washed out each night. Then more sea water is taken in. The factory is ready for the next day's work. The covers and other parts of the factory cost very little. Sea water and sun cost nothing. Most people of Symi are poor. So to them this new way of getting fresh water seems wonderful.

Ask someone what they have done to help the environment recently and they will almost mention recycling. Recycling in the homes is very important. However, having to recycle often means we already have more products than we need. We are just dealing with the results of that over-consumption in the greenest way, but it would be much better if we did not bring so many goods home.

The total amount of packaging（外包装）has increased by 12% between 1999 and 2005. It is 1/3 of a home's waste in theUK. In many supermarkets, food products are packaged twice with plastic and paper. Too much packaging is doing serious damage to the environment. The UK, for example, is running out of land because of this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Besides, the plastic from the package puts some creatures indanger, especially birds and fish.

Recycling helps, but the recyclingitself uses energy. The solution is not to produce such waste in the firstplace. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them have the idea that this cannot continue. For example, supermarkets should encourage customers to reuse their plastic bags.

But this is not just about supermarkets. It is about all of us. We have been used to the idea that packaging means excellence while anything unpackaged is of poor condition. This is especially true of food. But this idea has spread to other products, which often have farmore packaging than necessary.

There are signs of hope. As more of us recycle, we are beginning to realize just how many unnecessary goods are collected. We need to face the waste of our consumer culture, but we have amountain to climb.

An invention in front of your eyes

What is the most important invention of all time? Is it the written word that helps us to record information? Is it the telephone that lets us talk to people from all over the world? Is it the car that lets us travel at great speeds to meet others? Umberto Eco, an Italian writer, thinks it is something quite different. He says the most important invention might be bright in front of your eyes. He is talking about a simple pair glasses.

Modern eye glasses were invented around 1000years ago. They were more than just a convenient way to read. Before glasses, writers, scientists or teachers who could not see properly had to memorize everything. After about ten years of poor eyesight, they could not remember well enough and could not work. Glasses meant that people could work in their old age.

People who wanted to remember some information could write it down and read it. Eye glasses are one of the world's greatest inventions and were probably worn by the people who designed the first telephones and cars.
