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 growiing 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.
Both the article and lecture discuss if it is worthy to install box-shaped device around trees to eliminate the desertification problem. The article suggests that these devices have three drawbacks that might reduce its applicability. The speaker, on the other challenges the claim made in the passage and providing different perspective.
To begin with, the article states that the box-shaped devices are not cheap. Furthermore, the article pointed out that millions of these devices are required to solve the desertification issue. However, the lecturer responded that the writer of passage did not take into account that devices can removed from one tree and reused on the others. According to the speaker, these devices can be reused twenty times or more, which makes its price reasonable.
Furthermore, the passage claimed that it is tough to convince the people in dry areas to look after the devices. The writer elaborated that people in dry regions face difficult time to acquire food and other resources. In contrast, the lecturer stated that rewarded would solve this problem. She suggested that citizens of dry regions can use the devices to assist the growth of their vegetables and other plants. Furthermore, she said that after tress grow, people can use tree branches for fire.
Finally, the article suggests that these devices have limited ability to collect and conserve water. The writer claimed that devices would only help small trees, while large trees cannot survive in the harsh environment. The lecturer responded that device would help the trees to grow roots deep down in the soil, so it will be able to reach water. In addition, she mentioned that many large trees are still thriving two years after removing the device.
To summarize, while the passage thinks that box-shaped devices, which will be used to eliminate desertification, is not effective. The lecturer offers three counterarguments.
