    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.

Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic（遗传的） material. Foods from plants grown in this way are called genetically modified(改变的) foods, or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice is being prepared , for example , which stops people becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are,. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people , then hurt them or their children later. But both rich and poor countries are interested in their use, and they are not going to go away. In 2050, we may think differently about them.

What will the weather be like? Some people say they can know what the weather will be like from birds. When they see birds fly high out to the sea , they know it is a nice day, because birds don't like to fly out when it will rain. When the weather will be bad, the birds come back to the beach. A big wind may come with a rain. Birds do not like to fly in a big wind. They may sit in a tree when rain is coming. Other animals can also tell the weather. It's a cloudy day. The rain is coming. Chickens aren't quiet, and they are running here and there. Frogs(青蛙) are making big noise in the pool. If it is a nice day, the frogs will come out of the water.

Did you see snow in your hometown last winter? Did you feel it was warmer than before?
"There have been 21 warm winters in China since 1986," said scientists. They also said that in the past 100 years, as the global (全球的) temperatures went up by 0.74 ℃ , the temperature in North China has climbed 1.4 ℃ in only 50 years.
China needs to take quick action to cut carbon dioxide emission (排放) because it's the main reason for global warming. The good news is that China has seen the importance of going green. China set the goal of cutting energy use by 20% and pollution emission by 10% in the 11th Five-Year Plan.
Can you slow down global warming? Sure! You and your family can take steps to cut the amount of carbon dioxide that is sent out into the air.
Here are some pieces of advice to help you save the earth.
Wear used clothes. Wearing your brother's, sister's or dad's old T-shirt means you save the energy.
Change your light bulbs (灯泡). Use energy-saving light bulbs. And don't forget to turn off the lights when you leave a room and turn off your television and computer when they are not in use!
Ride the bus. Taking a bus saves a lot of oil every year.
Say no to plastic bags. The next time your parents go to the market, ask them to use baskets.
Open a window. Don't use the air conditioner, and let some fresh air in. When you have to use the conditioner, set the temperature higher in the summer and lower in the winter to save energy.
Make small changes in your daily life. Don't use paper cups, bags and boxes.
It's time for all of us to do something to save the earth.

Research proves that nearly half of the cancers diagnosed(诊断) in the UK each year-over 130, 000 in total- are caused by life choices that include smoking, drinking and eating the wrong things.

Tobacco(烟草) is the biggest factor, causing 23% for cases in men and 15.6% in women, says the Cancer Research UK report. Next comes a lack of fresh fruit and vegetables in men's diets, while for women it is being overweight. Lead author of the report, Professor Max Parkin, said: "Many people believe cancer is related to fate or in the genes(基因), and that it depends on luck whether they get it or not. Looking at all the evidence, it is clear that around 40% of all cancers are caused by things we mostly have the power to change."

For men, the best advice appears to be: stop smoking, eat more fruit and vegetables and cut down on how much alcohol you drink. For women, again, the best advice is to stop smoking, but also watch your weight.

In total, 14 lifestyle and environmental factors, such as where you live and the job you do, cause 134, 000 cancers in the UK each year.

Some risk（风险） factors are well founded, such as smoking's link with lung cancer. But others are less well recognized. For stomach cancer, a fifth of the risk comes from having too much salt in the diet, data suggests. Some cancers, like mouth and throat cancer, are caused almost entirely by lifestyle choices. But others, like gall bladder cancer(胆囊癌), are largely unrelated to lifestyle.

Public Health Minister, Anne Milton, said: "By making small changes you can cut your risk of serious health problems- giving up smoking, watching you drink, getting more exercise and keeping an eye on your weight."

A new camera made by a company named Netatmo has facial recognition software(面部识别软件). It can tell parents at work that their children have returned from school, or that a package has been taken to their home. It can also tell them if a stranger has entered their home.

Janina Mattausch is the product marketing manager for Netatmo.

"The common security(安全)camera at present are not that smart. They can tell if something is moving but they don't necessarily know if it's a human being or, ah, if it's your kids. They don't know the difference, so they will warn you all the time."

When family members enter a home, the new camera "recognizes(识别)" them and sends information to the owner's smartphone. The owner can choose to see the video then or later. But if an unknown person enters a home, the camera will send the warning that will cause an alarm to sound on the owner's smartphone.

That is what happened recently to an owner of the smart camera named Damien, He lives in Paris.

"On a Friday I was at work, attending(出席) a big monthly meeting when my phone warned. At first I told myself, 'Oh, it must be a mistake, maybe I have to set the system again.' But the notice on my phone was telling me that there was a movement in my flat and also a face that the software did not recognize."

He watched the video and was very surprised by what he saw. "I was watching it live on video. So I felt totally unbelievable and frozen. I asked a workmate to take me back home as fast as possible and I called the police on the way."

With the help of the video, the police found the intruder(闯A者) later that day.
