M: Rebecca, speaking of environmental stuff, I was reading about a drought in Australia. You guys have a serious drought problem with water?
W: Yeah, we do. We’ve had a drought for some time now and it seems to be getting worse and worse each year.
M: Well, how about this moment? Do you experience difficulties due to the lack of water?
W: Well, we actually have restrictions on water now. You can’t water your garden at all, but my mom loves gardening.
M: Then what do you do to keep your mom’s garden? It’s pretty hard, right?
W: Yeah,(13)my dad actually has fitted a special tube into the washing machine which filters the water out into a bucket outside and she can use that grey water to water all her plants.
M: That’s fantastic. It’s really a good way to make full use of the water.
W: Actually,(14)her garden is doing better with the grey water than normal water, especially grass. Maybe they really love those dirt nutrients from the clothes.
M: That’s interesting. But has the government done anything, such as raising water prices or limiting how much water you can use per month?
W: There’s a certain limit on water and the water prices are quite high now.
M: So, basically, everybody in Australia just has to hope that there will be more rain in the future?
W: Yeah. I think the problem is that(15)it needs to rain into the basins where we can catch the water; if it doesn’t, the water will just run off because the ground’s so dry.
