Marni: Hey, Gary, can you give me a hand with this recycling?

Gary，帮我搬一下回收垃圾好吗?

Gary: Why?

为什么?

Marni: Because I need to take it out to the recycling bin because the recycling truck’s coming tomorrow.

因为我要把它拿到回收垃圾箱那里，明天垃圾回收车就来了。

Gary: Oh, because you think someone’s actually going to reuse it?

你觉得真的有人会再使用这些垃圾吗?

Marni: Yes, I do. Because I know that it’s making a difference.

是的，我相信这会带来积极的改变。

Gary: Why? What’s the point?

为什么?有什么意义?

Marni: The point is to reuse it so that we’re not putting it in the landfill.

重新利用它们而不用将这些垃圾填埋。

Gary: It’s not going to make a dent in anything. It’s just going to go into another place where all this other stuff is, and it’s garbage!

这根本改变不了什么。它们只会被运到一个遍是其他垃圾的地方。

Marni: How can you say that? I believe in making a difference. I take public transportation everywhere. I recycle everything I can. I use minimal electricity. I limit my showers to only five minutes.

你怎么能这么说呢!因为我相信这能带来积极的影响。我去哪儿都坐公交车，尽最大可能回收东西。我的用电量很小，我每次洗澡都限制在5分钟里。

Gary: And I’m guessing you take public transportation…

我猜你坐公交车……

Marni: Uh-huh, I do!

是的。

Gary: …because you don’t want to contribute to hazardous waste that will make its way into the landfill.

因为你不希望自己的出行会产生将被掩埋的有害物质。

Marni: Well, I don’t want to contribute to greenhouse gases that are harming our atmosphere and causing climate change. But, yes, I think it is important that we all take strides to think about our impact on this planet.

我不希望自己的行为会加重温室效益，它会伤害大气，导致气候变化。但我觉得我们应该从自己做起，思考自身对地球的影响。
