Summarize the points made in the lecture, being sure to explain how they respond to the specific concerns presented in the reading passage.
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 author of the reading believes box-shaped devices used to fight against desertification will not be successful from the view of some scientists. The lecturer challenges the author's claim; she says the reason the writer mentioned is unconvincing and worth using to fight against desertification.
First of all, the reading asserts that the device is costly. In some cases, maybe some countries cannot afford the expense. Conversely, the lecturer argues that the cost is not a thing because we can use each device twenty times. After trees have grown, we can remove the device and use it for other trees.
Second, the writer claims that the local people should provide food for their families and maintain devices; it is challenging work. Maybe some people cannot do their daily job according to the maintaining it needs a considerable time. On the contrary, the speaker believes that these devices can help people grow their food, such as vegetables, because devices provide water. Furthermore, after trees are bigger enough for firewood, they can be part of the project.
Finally, the reading asserts that devices' abilities for collecting and conserving water are limited. Another problem is that after the trees have grown, how can they be alive in harsh environments, because in some territories, the drop of rain would not happen. In contrast, the speaker dismisses this issue because she mentioned that ninety percent of trees had not needed devices after two years in some research in the desert.
