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.
Both the reading and the lecturer discuss the aspects of using the device which collects water from vapor in the atmosfer to help the trees grow. The reading believes that this device has no ability to be successful against desertification, while the professor disagrees with the text in the following reasons.
First of all, the reading passage mentions that providing the box-shaped device in order to help tree growth is an expensive process, so some countries cannot afford to pay for millions of trees. The professor rebuts this argument by asserting that the devices are reusable and people can reuse them more than twenty times. Therefore the cost of devices seems to be reasonable.
Secondly, the author of the reading states that it is difficult to convince people to maintain the trees because they prefer to grow up the food resources like vegetables. The lecturer contracts that. He points out that those people who are affected by desertification can take part in the project by looking after their vegetables and other plants.
Finally, the author of the reading passage asserts that the capacity of water collecting is not much through the devices, however, the professor emphesizes those trees' long roots can provide more amount of water and nutrients for their growing up
