▶ Your Answer :
The reading passage suggests three methods
that can store Carbon Dioxide. However, the speaker brings several points
that can doubt those solutions.
The first point that the speaker made is that
adding iron to the ocean is not an effective way to store Carbon Dioxide into the ocean. It
is true that if we add iron in to the ocean, the number of phytoplankton will be
increase. However, it also needs nitrogen, so the number of phytoplankton will
not increase even though people add iron to the ocean. This refutes the reading
passage's assertion that adding iron can store Carbon Dioxide into the ocean.
Second, the lecturer argues that building
artificial wetlands is inefficient to reduce Carbon Dioxide. The lecturer admit that
natural wetlands can store Carbon Dioxide, and artificial wetlands can also store Carbon Dioxide.
However, the amount of Carbon Dioxide that artificial wetlands can store is much lower
than what natural ones can save. In addition, artificial wetlands need too much time to store. This casts doubt on the reading passage's claim that artificial wetland
can be a solution of Carbon Dioxide problem.
The last point made by the speaker is that
storing Carbon Dioxide in coal mines is not a good idea. It is true that coal can capture Carbon Dioxide as the passage claims. However, if coal capture Carbon Dioxide, it produce methane gas and will emit Carbon Dioxide; the solution becomes pointless. Moreover,
abandoned coal mines have small cracks, so if we store Carbon Dioxide into those mines, it
will leak.
