阅读理解 Sustainability(可持续性), one of the biggest topics of the last decade, has become the ray of hope to protect the planet. It's a topic we can't ignore and we must act now in a more sustainable way. What does that mean for the world of technology? E-waste is one of the planet's biggest contributing waste problems. Not only e-waste, but the materials that go into tech products are part of the problem. Take the smartphone industry for example, dozens of metals, minerals which have to be taken from the earth (including 16 of 17 rare metals) go into making phones. And with demand for mobile phones bigger than ever, it's a problem that needs to be solved. With a challenge comes an opportunity, and there's already some progress happening - great news for those of us wanting to be more sustainable with our tech. People used to turn their noses up at the idea of a second-hand product, but there's been a huge increase in demand for refurbished tech(翻新技术). For example, refurbished smartphone sales in the US have risen by 28% in the last 12 months while brand new sales have fallen by 21%. Many communities are making an effort to deal with e-waste as well. Cities, schools, or churches will sometimes hold events to collect e-waste and send it to recycling centers. Some companies even offer buy-back programs where people will be given cash if they turn in old devices. So the next time you want to deal with your e-waste, whether a smartphone, a laptop, an MP4 player or other, consider the more environmentally-friendly choices. It is possible to be sustainable with your tech after all. （1） What is the main purpose of paragraph 1? A . To explain what is sustainability. B . To introduce the topic of the text. . C .
