Pollution that lingers
- Some of the waste humans produce stays in the environment for a very long time.
- Two big problems are plastics and greenhouse gases 温室气体.
挥之不去的污染
- 人类产生的一些废物在环境中停留很长时间。
- 两个大问题是塑料(plastics)和温室气体(greenhouse gases)。
Pollution impact route · 污染影响途径
Trace how human materials create long-term environmental effects. · 追踪人类材料如何造成长期环境影响。
Most plastics are a problem because they are: · 大多数塑料之所以成问题，是因为它们：
Non-biodegradable plastics persist and harm wildlife. · 不可生物降解的塑料会持续存在并危害野生动物。
Plastic that breaks into tiny pieces that persist in the environment is called . · 破碎成微小碎片并在环境中长期存在的塑料被称为。
Microplastics spread through food chains. · 微塑料会通过食物链传播。
Plastic pollution
- Most plastics are non-biodegradable 不可降解 — they don't rot away.
- They build up in oceans, harming wildlife that eats or gets tangled in them.
Greenhouse gases trap heat leaving the Earth, so the Earth gets warmer
塑料污染
- 大多数塑料是不可生物降解的(non-biodegradable)——它们不腐烂掉。
- 它们在海洋中积累,伤害吃它们或被它们缠住的野生动物。
温室气体捕获离开地球的热量,所以地球变得更暖
Which are greenhouse gases? (Select all that apply.) · 哪些是温室气体？（选择所有适用项。）
CO₂ and methane trap heat; oxygen and nitrogen do not. · CO₂和甲烷能捕获热量；氧气和氮气不能。
Greenhouse gases cause global warming by: · 温室气体通过以下方式导致全球变暖：
They trap heat — the greenhouse effect. · 它们捕获热量——即温室效应。
Greenhouse gases
- Carbon dioxide (from burning fuels) and methane 甲烷 trap heat in the atmosphere.
- This greenhouse effect is making the Earth warmer — global warming 全球变暖.
温室气体
- 二氧化碳(来自烧燃料)和甲烷(methane)在大气中捕获热量。
- 这种温室效应(greenhouse effect)使地球变得更暖——全球变暖(global warming)。
Global warming can cause ice to melt and sea levels to rise. · 全球变暖会导致冰川融化，海平面上升。
Warming threatens habitats and food supplies. · 变暖威胁栖息地和食物供应。
Effects of climate change
- Rising temperatures cause melting ice, rising sea levels, and changing weather.
- This threatens habitats, food supplies and many species.
Non-biodegradable doesn't mean it disappears. Plastic just breaks into smaller and smaller pieces (microplastics 微塑料) that persist for centuries and spread through food chains.
气候变化的影响
- 上升的温度引起冰融化、海平面上升和变化的天气。
- 这威胁栖息地、食物供应和许多物种。
不可生物降解不意味着它消失。 塑料只是碎成越来越小的片(微塑料),持续数个世纪并通过食物链传播。
You've got it
- most plastics are non-biodegradable, building up and harming wildlife
- CO₂ and methane are greenhouse gases that trap heat → global warming
- climate change melts ice, raises sea levels and threatens habitats and food
你掌握了
- 大多数塑料是不可生物降解的,积累并伤害野生动物
- CO₂ 和甲烷是捕获热量的温室气体 → 全球变暖
- 气候变化融化冰、提高海平面,并威胁栖息地和食物
