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 reading states that the approach of using some devices which collect water for growth of trees in desert land, cannot be the best course of action and provides some reasons for this theory. The lecturer, however, finds the idea dubious and casts doubt on the reasons proposed by the reading passage.
The author argues that for desertification approach they need to plant millions of trees and providing these device for all the trees cost expensive. Conversely, the lecturer brings up the idea that this devices can be reused for twenty times which results in a decrease in the expense.
Furthermore, the reading passage holds the view that installing and keeping these devices need the help of local people, but they may not be incentive to cooperate due to the fact that these trees do not provide any source of food for them. On the contrary, the professor underlines the fact that the project have two advantages for local people. First, they can be alloweded to use these devices for other plants and produce vegetables for themselves. Second, the branches of trees can be used as firewood which give them the chance to cook their foods.These two benefits can stimulate them to take part in this project.
Finally, the reading states that these devices are useless for bigger trees and they will not be able to help the growth of trees when they become bigger. In contrast, the speaker dismisses this issue due to the fact that these devices help trees to grow long roots by which they have the access to the source of water underground. As a result, trees can be survived independently. For example, 90 percent of trees in Sahara have survived without the help of these kind of devices.
