In the given a set of materials, the reading and the lecture both deal with carbon sequestration. The lecturer challenges the reading passage’s argument that there are some effective ways to reduce a mount of Carbon Dioxide in the atmosphere by using carbon sequestration. First of all, the author contends that adding iron into the ocean to increase phytoplankton is one of the methods. In contrast, the lecturer refutes the claim by saying that it is not effective way to increase phytoplankton. When their population increases quickly, nitrogen is depleted, which lead to a decrease in the overall population of phytoplankton. A recently study shows that only small amount of Carbon Dioxide in the atmosphere can be decreased. So, the lecturer insists the statement made in the reading is false. Second, the writer insists that making artificial wetlands is the vital method to reduce Carbon Dioxide in the air. The speaker, however, rebuts the argument by asserting that storage capacity of artificial wetlands is smaller than that of natural ones. Moreover, it takes a long time to fully develop artificial wetlands, making it inefficient. Thus, the speaker maintains the notion made in the reading is erroneous.
Finally, the article argues that storing Carbon Dioxide in the coal mines is another effective way to reduce the amount of Carbon Dioxide in the air. On the other hand, the professor counters the contention by stating that methane is emitted when Carbon Dioxide contacts coal. Carbon Dioxide is emitted into the air as well since Methane has it. Furthermore, not all of the Carbon Dioxide stick to the coal; some of them would be leaked out into atmosphere. For these reasons, the total amount of Carbon Dioxide cannot be decreased. Therefore, the professor argues the idea made in the reading does not make sense.
