B
(2025·武汉期末)① Have you ever chatted with a smart AI assistant on your phone or computer, like asking it to help you with your homework? They're pretty amazing, right? ★. Scientists from the Chinese Academy of Sciences and Reichman University in Israel have found that these clever AI helpers, also called LLMs(Large Language Models) might be causing some trouble for our environment.
②Have you noticed that your phone tends to heat up when you are playing video games? That's because it uses a lot of energy. AI systems, especially the ones that can chat and create stuff(东西), need even more energy. They're like power-hungry brains that need lots of computer parts and special places to live, which means they use up a lot of resources(资源).
③Now, think about your old toys that you've outgrown and thrown away. Last year, we only had to throw away 2.6 thousand tons of electronic stuff that was used just for AI. But by 2030, because of these AI systems, we might have to throw away between 1.2 million and 5 million metric tons more. And here's the kicker: the total amount of electronic waste from all our tech is expected to jump by about a third to 82 million metric tons by 2030.
④So, while these AI systems are super cool and helpful, they're also making our already big problem of electronic waste even bigger. It's something we should all be aware(意识到的) of as we use more and more technology in our lives.
