Transcriber: Andrea McDonough Reviewer: Bedirhan Cinar Coral reefs are some of the most spectacular ecosystems on the planet.
2
They're also some of the most vulnerable.
3
But how can we protect the reefs and the animals and plants who rely on them?
4
And how can we make sure our protected areas aren't hurting those who use reefs to survive?
5
These are some of the big questions facing marine conservation biologists today.
6
Let's take Fiji, for example.
7
Fiji is series of islands in the South Pacific Ocean.
8
To help balance the need for conservation and making a living, scientists had suggested that instead of one big park which provides a lot of coverage for one reef system while leaving the rest unprotected, a better way is to create a system of protected areas nested together like pearls on a string.
9
This idea is called connectivity.
10
In this way, scientists can protect lots of different habitats while not excluding people from their traditional fishing grounds.
11
Now, the only way this string-of-pearls kind of reserve network is going to work is if each park is connected to other parks.
12
There are two main benefits to this.
13
First of all, insurance.
14
If something bad happens to one park, say, an oil spill or coral bleaching, then because that park is part of a system, it can be reseeded from other parks that escaped the event.
15
The second benefit is representation.
16
By conserving many different areas, scientists ensure that lots of different habitats get protected.
17
This way, they can make sure all the different marine habitats in Fiji, such as coral reefs, mangroves, and sea-grass beds, are all represented.
18
This way, we don't unduly settle any particular village or group of people with the economic burden of having their fishing grounds off-limits.
19
By sharing the cost around the communities, they can also share the benefits.
20
So if we agree that rather than one big park, we should have lots of parks of different sizes and covering different habitats, then scientists need to make sure those smaller parks are connected, because if they're not, they probably won't be self-sustaining.
21
But how do we know that?
22
That's where genetics and DNA come in.
23
By looking at how closely related the fish in each one of these small reserves in Fiji are to each other, scientists can figure out how much migration is going on among the reserves within the system.
24
Now it's important to look at a variety of different species because there's no guarantee that what's going on with these guys is what's going on with these guys.
25
But if we look closely and at enough species, we can see whether or not the necklace is working.
26
What scientists have found so far is that, in general, there's a fair amount of connectivity amongst the parks within Fiji.
27
But it's not just a big free-for-all; rather, it seems that, for some species, babies born in the far west are having a hard time making it to the islands in the far east.
28
To help deal with that, conservation biologists are suggesting that there be enough parks in both the east and the west to keep the populations healthy.
29
This isn't just in Fiji, either.
30
Lessons about reserve connectivity can help across the world.
31
In places like Indonesia, Papua New Guinea and the Bahamas, scientists are using a variety of tools to help understand how individual parks can function together, so that their sum is greater than their whole.
32
And this way, we can keep the beautiful necklace that is our coral reefs, intact.

关于本课程
在本课程中，学习者将通过分析约书亚·德鲁的演讲，了解如何保护易受威胁的珊瑚礁生态系统。通过运用听力和口语练习，提高英语发音能力，掌握与海洋保护相关的专业词汇。此外，学习者还将探索连接性和生态保护的重要性，增强对于环境科学的理解。
关键词汇与短语
- 珊瑚礁 (Coral reef): 世界上最美丽且脆弱的生态系统之一。
- 连通性 (Connectivity): 不同保护区之间的联系，有助于生态系统的恢复。
- 生物多样性 (Biodiversity): 不同生物物种的丰富程度。
- 生态系统 (Ecosystem): 生物与环境之间的相互作用。
- 油污泄漏 (Oil spill): 对海洋造成破坏的一种污染事件。
- 保护区 (Protected area): 为保护生态环境而设立的区域。
- 迁徙 (Migration): 生物在不同栖息地之间移动的现象。
- 海洋保护生物学家 (Marine conservation biologists): 研究海洋生物及其保护的科学家。
练习技巧
在观看视频时，建议您使用shadowing技巧，模仿演讲者的语调和节奏。约书亚·德鲁的演讲语速适中，适合进行详细的shadow speech练习。您可以先播放短片段，集中注意力在发音的连贯性上，然后逐句模仿其发音。为获得最佳效果，建议您暂停视频并重复相关句子，通过这种方式可以显著提高英语发音。
此外，通过看YouTube学英语，您能找到其他类似的教学视频，帮助您更好地理解内容，提升自己的语言能力。记得时常反馈自己模仿的表现，并与他人交流，以帮助进一步巩固所学知识。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
