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.
In the lecture, the professor believes that desertification is an effective method to solve the problem, and none of the stated drawbacks is convincing. This casts doubt on the reading which states that the device would not be successful to limit the issue.
To begin with, the lecture states that the instrument would not cost that much. In fact, the device is reusable because scholars can use the device again when the old tree grow up. Furthermore, one instrument can be used to grow 20 different trees. This contradicts the article which claims that growing trees is expensive.
In addition, the speaker claims that is true that frame would be asked to install and look over trees, but they would receive benefit too. This is because by collecting water they will feed the trees along with their crops such as vegetables. Furthermore, when trees grow up farmers can use the trees Barnes as fire wood. This refutes the text which states that locals would not get benefit; thus they would not be happy to help.
Finally, the professor explains why trees can thrive inside the device. This is because trees extend their roots inside the device which allow them to absorb underground water. Moreover, research states that when they used the same manner in Sahara dessert, 90% of trees thrive after removing the device from them. This opposes the text which states that the device could not provide suitable environment for trees to grow.
