Listen to a conversation between a student and her biology professor.

Professor
So I heard that your field work ended up camping a few days longer than expected.
Student
Yeah, the bus broke down. It gave us time to gather more specimens from the lake
to study in the lab but unfortunately 1 admit missing a day of classes, including the
class when you describe the requirements for the paper.

坏掉了，所以多花了几天，错过了教
授的课所以不知道论文的要求是什么

Professor
Ur, that brings back memories from my undergraduate days.
（

So anyway what
I'm
looking
for
is
an
ecological
situation
in
which
the
solution
causes
a
much
greater
problem
than
the
original
problem
it
was
intended
to
solve.
（

The
example I gave in class was about cane toad in Australia. They were imported there
in 1935 to control the grayback cane beetles that were destroying the sugar cane

.
crops.
Student
And what? The plant backfired?
Professor
Yep. It
’
s a classic case of biological control done awry. The toads ate some beetles
but they also ate many other animals and they're poisonous and being an imported
species they had no natural predators.
Student

Not good.

Professor
Definitely
not.
Even
worse,
the
toads
had
no
effect
on
grayback
cane
beetle
populations either. Hum, so tell me what do you have in mind for, your paper.
教授简单 讲了一下论文的题目：生态系统中一个问题的解决方案往往创造更多问题。举例，

Student
Well, I got the idea from a radio interview I heard.
（

）
It was Winstly ecologist to
claim that the greatest threat to the greatest number of species in the next 25 years
is not global warming as one would expect but the cultivation of oil palm trees.
Professor
Ah, yes. There's been a lot of talk recently about whether oil palm plantations are
harmful to biodiversity. Some areas report losing as much as 80% of the native bird

.
and butterfly populations and the oil palm is being cultivated in so many places in
the world now.
Student
Everybody
thought
it
was
a
short
winner,
and
made
a
lot
of
sense
both
economically and environmentally.
（

）
Here's a crop that's in high demand, easy to
grow and won't disrupt the ecosystem.

Professor
Or so they thought. It's a good topic.

学生说明了自己论文的想法，想写
palm
tree
种植所带来的危害，因为
palm
tree
降低了
biodiversity
。但是人们觉得
palm tree
很好，因为高产，容易种植，而且不会扰乱生态系
统

Student
So in my write the paper should be divided into two sections?
Professor
Yes. In the first section, you describe the practice, the history of where and how it
was implemented, the degree to which it has been successful, and why and how it
has become a conservation problem or a potential problem.
Student
Right. And the second part is about how to develop a suitable policy to deal with
the problem?
Professor
Exactly. The second section should also include the pros and cons associated with

.
oil palm cultivation. I'm interested to see what you come up with.
Student
You mean, because it's not all bad.

Professor
Right. Oil from the oil palm happens to be very useful.
（

）
It's in so many products,
from food to alternative fuel and some of the communities in the regions where the
crop was introduced have really flourished. There is a lot to consider. It
’
s definitely
not a clear-cut situation.
最后提了学生的论文内容要分成两个部分。
第一部分是综合介绍

第二部
