Species on the edge
- Some species have so few members left they may vanish.
- These are endangered species 濒危物种.
- If the last one dies, the species is extinct 灭绝 forever.
- Extinction is permanent — there is no undo.
濒临边缘的物种
- 有些物种剩下的成员如此之少,以至于它们可能消失。
- 这些是濒危物种(endangered species)。
- 如果最后一个死亡,该物种就永远灭绝(extinct)了。
- 灭绝是永久的——没有撤销。
The main threats
- Habitat destruction 栖息地破坏 is the biggest threat by far.
- Clearing forests and draining wetlands leaves species homeless.
- Overhunting takes more animals than can be replaced.
- Pollution, invasive species, and climate change add more pressure.
主要威胁
- 栖息地破坏(habitat destruction)是迄今为止最大的威胁。
- 清除森林和排干湿地让物种无家可归。
- 过度捕猎带走的动物多于能被替代的。
- 污染、入侵物种和气候变化增加更多压力。
An endangered species is one that… · 一种濒危物种是……
An endangered species has so few members left that it could go extinct without help. · 一种濒危物种剩下的成员如此之少,以至于没有帮助就可能灭绝。
How we protect them
- Protected reserves give species safe places to live.
- Laws ban hunting the most endangered animals.
- Captive breeding raises numbers, then returns animals to the wild.
- International trade bans stop the sale of endangered species.
我们如何保护它们
- 保护区给物种安全的居住地方。
- 法律禁止捕猎最濒危的动物。
- 圈养繁殖提高数量,然后把动物送回野外。
- 国际贸易禁令阻止濒危物种的买卖。
Pushes toward extinction, or helps survival? · 推向灭绝,还是帮助生存?
Sort each item into a threat that endangers a species or an action that protects it. · 把每一项归入危及物种的威胁或保护它的行为。
The biggest single cause of species endangerment is… · 物种濒危最大的单一原因是……
Habitat destruction · 栖息地破坏 — clearing forests, draining wetlands — is the leading cause of endangerment. · 栖息地破坏——清除森林、排干湿地——是濒危的首要原因。
When the very last member of a species dies, the species is ____. · 当一个物种的最后一个成员死亡时,该物种就____了。
A species is extinct once its last individual is gone — a permanent, irreversible loss. · 一个物种一旦最后一个个体消失就灭绝了——一种永久的、不可逆转的丧失。
Why it matters
- Every species is part of a web of life.
- Losing one can unbalance a whole ecosystem.
- Species also give us food, medicine, and beauty.
- Once gone, a species can never be brought back.
为什么它重要
- 每个物种都是生命之网的一部分。
- 失去一个能使整个生态系统失衡。
- 物种还给我们食物、药物和美。
- 一旦消失,一个物种永远无法找回。
Protected reserves and anti-hunting laws can help endangered species recover. · 保护区和反狩猎法能帮助濒危物种恢复。
Safe habitat plus protection from hunting gives endangered species a chance to rebuild their numbers. · 安全的栖息地加上免受狩猎的保护,给濒危物种一个重建数量的机会。
Select all · 所有 threats that endanger species. · 选出危及物种的所有威胁。
Habitat loss, overhunting, and pollution all endanger species. Reserves protect them. · 栖息地丧失、过度捕猎和污染都危及物种。保护区保护它们。
Extinction is different from every other environmental problem in one way: it is permanent. A polluted river can be cleaned; a thinned ozone layer can recover. But when the last member of a species dies, that species — and everything it did in its ecosystem — is gone for good. That's why protecting endangered species before they vanish matters so much more than reacting after.
灭绝在一个方面不同于其他所有环境问题:它是永久的。一条污染的河能被清洁;一个变薄的臭氧层能恢复。但当一个物种的最后一个成员死亡时,那个物种——以及它在生态系统中做的一切——永远没了。这就是为什么在濒危物种消失之前保护它们,远比事后反应更重要。
Saving a species from the brink:
- A rare bird is endangered: its forest is being cleared (habitat destruction) and hunters take the last ones.
- Conservationists create a protected reserve, ban the hunting, and start a captive-breeding program.
- Slowly the numbers climb, and birds are released back into the safe forest — a species pulled back from the edge of extinction.
把一个物种从边缘救回:
- 一种稀有的鸟濒危:它的森林正被清除(栖息地破坏),猎人带走最后的几只。
- 保护主义者创建一个保护区,禁止捕猎,并开始一个圈养繁殖项目。
- 慢慢地数量攀升,鸟被放回安全的森林——一个从灭绝边缘被拉回的物种。
An endangered species is at high risk of extinction — a permanent loss. The biggest threat is habitat destruction, followed by overhunting, pollution, invasive species, and climate change. We protect species with reserves, hunting bans, captive breeding, and trade bans. Because extinction cannot be undone, prevention matters most.
一种濒危物种有很高的灭绝风险——一种永久的丧失。最大的威胁是栖息地破坏,其次是过度捕猎、污染、入侵物种和气候变化。我们用保护区、狩猎禁令、圈养繁殖和贸易禁令保护物种。因为灭绝无法撤销,预防最重要。
