▶ Your Answer :
To solve the problem that shrimpers accidentally catch the endangered sea turtle species, TEDs are provided. The reading passage claims that the TEDs have several disadvantages and mention the reasons for them. The lecturer opposes the reading passage's arguments for the following reasons.
First, the writer suggests that the accident turtles get trapped are not happening much. It might be only one turtle caught by shrimp-fishing boat so it is inefficiency that they set TEDs on their boat to save these small numbers of turtles. The speaker points out that they should think as whole numbers of turtles captured. There are thousands of shrimp-fishing boats in United States. Thus, it can be interpreted that thousands of turtles are captured by accident a month.
Next, the reading passage claims that there are other methods to save sea turtles. For example, shortening the time limit of nets underwater can be more effective. However, the professor contradicts the mention with technical problems. They need a lot of monitors to check the time of nets underwater but there are not enough monitors to use. So TEDs are the best way to protect sea turtles so far.
Last, the writer asserts that TEDs are not big enough to catch big species of sea turtles such as loggerhead. These animals are too large to get out along the route TEDs make. But, in the lecture, she mentions that TEDs are modified easily. When shrimp fishers figure out the big size of turtles, they can change their TEDs' size. So new larger TEDs will be no longer problem. |
