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 and the lecture are both about the methods of improving dessert land quality. The author of the reading doesn't think growing trees in boxes will help to solve this problem. The lecturer challenges the claims made by the author. She is of the opinion that it works well.
Firstly, the article argues that fee to install device costs much. It states that several countries can not afford to buy these. But the professor casts doubt this by mentioning that even it is expensive to buy all boxes, we can reuse up to 20 times. She adds that when the tree grows up, we can take the device out to use for young trees.
Secondly, the reading notes that in order to use the machines, it is necessary for locals to join in the project. It mentions that because the project does not provide foods for residents, it is very hard to ask them take part in. This casts doubt ideas by the lecturer. She states that we can give reward for local people when they agree to join in with this plan. Shen contents that when collecting for water helps them to grow for their foods. Moreover, when trees grow up, they can use branches to use for fire woods. As a result, residents can take benefit all of foods and fire woods, so they surely agree to do maintenance.
Finally, the author of the article thinks that water collection and conservation is not enough to help trees grow up. The professor elaborates this by mentioning that water goes inside the tree roots. Therefore, trees can grow up quickly by watering the roots. In addition, she explains that 90 percent of trees can survive well after 2 years of removing the devices.
