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 lecturer refutes all three arguments presented in the reading passage about a box-shaped device used to fight against desertification. The process of turning to arid and non-usable land due to the change in climatic conditions is termed as Desertification.The reading claims that these devices are not sufficent and sucessful. However, the professor argues that it is worth-while to use this device and she is providing a counter-argument for each of the assertions.
First of all, the reading suggests that it is expensive to fix the device around each young tree as there are millions of trees to plant for the prevention of desertification. The professor, on the other hand, says that when the tree gets bigger they can remove it and can be used for other younger trees. In other words, it can be reused for at least 20 times. Therefore the benefits outweigh its cost.
Second, the reading passage points out that the installation and maintenance of the box-devices are an arduous job and need the support of the local community. Since the people didn't receive any benefits from these devices, we cannot compel them to take care of the devices. The tutor contradicts this by contending that the government is providing rewards for the community if they help in this project. Furthermore, they can collect water from the devices and can use it for plants to grow vegetables and many more. Also, they can use the branches of the fully-grown trees for firewood. From these ways, the government can motivate people to join the project of successful implementation of box devices.
Finally, the lecturer denies the claim that these devices can collect only a limited amount of water for the use of trees. She tells that once the roots of the young trees go deep to collect the underground water, they can sustain itself without the box devices. For instance, the professor explains that in the Sahara desert, the trees survived 2 years after the devices had been removed. Therefore, the prolonged use of box-devices is not needed so its defects can be waved.
