The population of Earth is still going up. There will be less and less good land for growing crops in the future. People worry that there will not be enough food for everyone in the middle of this century.

Recently scientists have discovered one strange plant

named fedtschenkoi（玉吊钟）may help. It can absorb（吸收）carbon dioxide(CO₂)

at night. It only needs 10 times less water than food plants like beans. This means it

can grow in the desert(沙漠).

In which ways could this plant help us?

Since deserts are increasing in size because of the changes in Earth’s climate, growing plants there will be more and more important. Although it is dangerous to

eat this plant, scientists can still study something about it: how it absorbs CO₂ at

night while many other plants only do this during the day, and why it is suited to the

desert.

There is another direction to take the research in. Producing a desert plant to eat

will be difficult, but there is still possibility to use the genes(基因)from this plant and put them into food plants.

The other way is to grow this type of plant for fuel(燃料). At the moment we

grow plants for fuel in good land. If we do it in deserts instead, more good land can be used to grow plants for food.

Desert plants have special qualities, which could be an answer to our future food

or energy needs. Scientists are working hard on it.

The population problem may be the greatest one of the world today. The world’s population is growing faster and faster. Two thousand years ago, there were only 250 million people on the earth. Four hundred years ago, the number was over 500 million. But at the beginning of the 20th century, the world’s population was about 1,700 million. In 1970, the number was3,600 million. In 1990, the number was five billion. A UN report said that the world population had passed six billion by the end of the 20th century. This was just ten years after it reached five billion. By October 31, 2011, with a new baby’s birth, the world’s population has reached 7 billion. But another billion is coming by 2025, and the total will reach 10 billion before the end of the century.
