Because of climate change, more and more land that was once used to grow crops or provide food for animals is turning to dry, unusable desert land. There are many proposals about how to stop this process, known as desertification. A number of proposals involve growing trees, because trees can help protect soil and provide many other benefits to fight against desertification. Some scientists have proposed that the best way to grow trees in dry areas in danger of desertification is by using a box-shaped device surrounding the young tree. The device collects water that condenses from vapor in the atmosphere and helps the tree to grow. However, other scientists believe that this device will not be successful in fighting against desertification for the following reasons.
First, at a cost of 25 U S. dollars each, the device would make growing trees a prohibitively expensive process. Meaningful efforts to fight desertification involve growing millions of trees. Some countries most affected by desertification cannot afford to buy devices for millions of trees
Second, plans for fighting desertification involve asking local people to install and maintain the devices. People living in some of the areas most affected by desertification work long days in harsh conditions: sometimes barely managing to provide food for their families. It would be difficult to motivate these people to look after trees that cannot serve as a source of food for them.
Third, the device's ability to collect and conserve water is limited. Each one provides only enough water to keep a small tree alive. Trees that have outgrown the device have to deal with unforgiving environmental conditions on their own. In some places where the devices are being tried, six months can pass without a drop of rain. Once the trees become too big for the device, they may not be able to survive in such a harsh environment.
The passage provides information regarding a device which aids trees to grow up in the desert lands. The professor presents points which contradict with the points mentioned in the passage. These contradiction will be elaborated in the following paragraphs.
Firstly, according to the passage using this device would charge the governments or other related organizations a huge amount of money. However, the professor illustrates that each device could be used for more than 20 young trees, as a result of which the cost for each tree would not be so much.
Secondly, as it is stated in the passage the program of desertification by means of the mentiond device would engage people who live there with the process of installing and maintaining the device in order to growing trees that would not have any benefit such as food and fruits for them. On the contrary, based on the information from the listening, the device is able to help irrigating other plants like vegetables, so it can motivate inhabitants to try maintaining these devices.
Last but not least, the reading passage notes that the capacity and power to collect water is limited in those devices and that would lead to failure in addressing the problem of lacking precipitation in dry areas, especially for huge trees. The lecturer, however, says that it is not true and based on the statistics 90% of trees would survive even 2 years after removing the device. Furthermore, when the trees grow adequately their roots move too deep and lie under the dry surface.
