Listen to the following dialogue and interpret it as required. After you hear a

A：今年，最重要的议题是塑料问题。从食品袋到塑料吸管，再到包含在肥皂和化妆品中的各种微珠，地球己被塑料淹没，而且这种情况还会长期继续下去。那么我们能做些什么?这个问题有多严重?
B: Well, in 2015, we were able to estimate the input of plastic from our mismanaged waste around the world, and into the ocean, and that is equal to about eight million metric tons of plastic entering the oceans every year. So if you think about it, that’s equal to about a dump truck of plastic every minute going into the ocean. It’s5 very significant.
A：以我们对塑料的了解，还有望解决这个问题吗?塑料进入海洋后，需要多长时间才能溶解或降解?
B: It really doesn’t ever biodegrade that we’re aware of. And what it does instead is fragment over time into smaller and smaller pieces. So a large plastic item then ends up as many small micro plastic items.
A：我在想这些微塑料是不是最终会进入水生生物体内，因为它们认为这是食物?
B: Certainly some of this is very much like food that animals in the marine ecosystem eat. And then we know that even some of the smallest items like the microbeads can be consumed by some of the smallest animals in our food web like zooplankton .
A：每分钟就要倾倒一车的塑料，面对这么严重的问题，你我这样的普通人能否尽一点绵薄之力呢?有哪些措施是我们普通人也能做的?
B: Reusable water bottle, reusable coffee mug, reusable bag, and no straw. I know we’ve heard them before, but our research really shows, taken collectively and over a period of time, those choices really have an impact.
A：在可预见的未来，我们是不是可以研制出一些高科技材料，既能当作塑料用，从长远来看，又不会对环境构成这么大的危害?
B: Well, we’re looking at polymers now. Of course there are things that still need to be managed within our waste stream, but I do think that thinking about new materials and product design is very important.
